... to work with Dock Managers.


Gigasoft has uploaded version on 05/21/21.

Version 9.8 adds .Net50 / .NetCore Winforms and WPF interfaces for Windows Desktop development. The ProEssentials install folder now includes a new sub folder DotNet50 and new VS2019 example projects targeting .Net50 are located in the C#.NET50 and WPF-C#.NET50 sub folders.

Gigasoft also published NuGets on as publisher GigasoftInc

.Net Charting at

Note that VS2019 .Net50 projects can only add tools to the toolbox via the Manage NuGets Packages... feature to add our NuGets to the project. Search for Gigasoft.

Note, v9.8 AnyCpu assembiles found in our DotNetAnyCpu sub folder (Winforms, Wpf, Webforms), and DotNet50 sub folder (.Net50-Winforms and .Net50-WPF) now embed our native DLL (PEGRPG.DLL) inside the assembly. This change will change how you distribute your project if using the AnyCpu variations. Our AnyCpu assemblies are now the only file you need to distribute with your exe. When our controls instantiate, if needed, the control will unpack the necessary embedded DLL automatically. See the readme files within our DotNetAnyCpu and DotNet50 folders for more information.

When using our AnyCpu files within Visual Studio, the first time a control is dragged from toolbox to a form, Visual Studio should have been started with Admin privileges. Subsequent sessions will not require Admin.

If you purchased ProEssentials, place the file Gigasoft.ProEssentials.Dll or Gigasoft.ProEssentialsWpf.Dll from our DotNetAnyCpu or DotNet50 folder into the package folder that is holding the NuGet package for your project. This will remove the eval prompt and build and publish the retail version of Gigasoft.ProEssentials.Dll or Gigasoft.ProEssentialsWpf.Dll The Dll files installed with our Setup exe will stamp your company name and serial into files you distribute.

1) Fixed an issue with WPF scroll thumb positions when mouse wheel zooming was followed by a programmatic chart update would cause the thumb postion to revert to beginning of scrollbar.
2) Fixed an issue with CursorMode = DataCross and CursorMode = DataSquare and RenderEngine = Direct3D.
3) Fixed an issue with CursorMode = DataSquare and Direct2D.
4) Fixed PEP_dwaPOINTCOLORSPTR which was broken and preventing the option for application defined data to be used for PointColors.
5) The WPF interfaces have been improved to automatically call Invalidate at end of _Loaded event.
6) The WPF inetfaces include a new read only property PersistenceDataExists.

The above items 5 and 6 improve our WPFs for use within Tab containers, or any container that causes the control to be _Unloaded and _Loaded. See the readme file located with our WPF-C#.NET example projects.

1) Fixed a random issue when exporting charts using RenderEngine = Direct3D as bmps, jpegs, pngs from within an application running on vmware. CreateTexture2D was failing due to the vmware graphics driver randomly not always supporting MSAA. Now we test for this possiblility and revert to non-MSAA export if needed. Since WPF interfaces also use CreateTexture2D as they draw to a texture as part of their normal rendering, we added similar test logic to potentially catch any similar issue running wpf based applications on vmware.


Gigasoft has uploaded version on 12/09/20.

1) Early 9.7's new quick annotation feature interferred with horizontal and vertical line annotation types of NoLine or (-1) so be sure to use latest v9.7 to avoid this issue.
2) Fixed an issue with 2d contours where all magnitude/zdata was negative and also had a max magnitude of zero.
3) Fixed an issue with 2d contours and very many divisions (100s to 1000) causing an odd legend with too many legend labels.
4) Fixed an issue with 3d data and annotation highlight feature where the highlighted symbol was still being shadowed even though DataShadows feature was set to disable shadowing.

Version 9.7 continues to add to RenderEngine = Direct3D rendering technology to mimic features found in Direct2D. v10 is getting closer to release, and will easily support porting, so we greatly appreciate customers taking advantage of buying 9 now and getting 10 for free. v10 is taking longer than expected as we are now also refactoring Direct3D construction onto the gpu. ProEssentials is very fast, but moving to gpu based construction will help with plotting billions of data points and the speed will be the absolute fastest available. ProEssentials will soon once again be the fastest most professionally and meticulously rendered scientific, engineering, large information system charting engine available. v10 is also adding jagged data (individual subsets will have their own new storage) with inherent per subset circular buffer features which the gpu will also utilize incrementally. v10's level of sophistication will be top-class, so because of delays, we decided to release v9.7 with a few v10 additions.1) Pe3do 3D Log scales in X Y Z for all plotting methods, annotations, and features, and Direct3D Pesgo 2D Log support. See examples 139, 402 and 404. See PeGrid.Configure.XAxisScaleControl, and LogScaleExpLabels to optionally show log scales in normal numeric format instead of scientific notation.
2) Pe3do new property GridBandsPatching. Set to false to disable grid patching and enable grid strips of GridBandsColor.
3) New Quick Draw Tooling / Annotation feature as part of Pesgo, Pego, and Pepso. See demo project example 110 for a working demonstration. Running this example, left-click + drag, draws a round rect selection tool with data-coordinate-sizing prompts. This feature allows for a fully customized annotation layer to be constructed and displayed and hidden without overhead of reconstructing the underlying image.
4) New colored Cursor and line styled Cursor are also available as part of the new quick drawing feature. See example 105.
5) The WPF interfaces have been improved to use the new colored and styled cursors by default. The CursorMode feature was problematic with the older WPF interfaces as they attempted to rely on ROP2 drawing logic that was highly efficient at drawing a cursor without any additional memory or processing requirements; however, WPF is too non-Windows to get this to work in all scenarios. The new approach draws the cursor to a prepared bitmap and the composite scene is then refreshed and solves all CursorMode concerns.
6) Fixed a cursor flicker issue when combining CursorMode feature with tooltip CursorPromptTracking feature.
7) Fixed CursorMode repeat keyboard processing when holding arrow keys within the WPF interface.
8) Fixed z order issues with RenderEngine=Direct3D 2D rendering to honor subset order similar to Direct2D and SubsetsToShow and RandomSubsetsToGraph features.
9) Fixed Pego MouseWheel zooming out issue with large data sets.


Gigasoft has uploaded version on 9/25/20.

1) Improved Pego and Pesgo axis grid construction for very small ranges of data.
2) Improved Pego and Pesgo data reduction filtering logic to better handle non-linear distributions of data. For example, cases where over time (x axis) the quantity of data samples exponentally increases. Now the data reduction maintains a visual perfect representation as if all data was plotted.
3) We removed embedded Jpeglib bits from our DLL. We were notified that our DLL was being flagged as having a potential medium vulnerability CVE-2013-6629 when used with corporate license manager FlexNet. ProEssentials does not and did not have this vulnerability as our DLL never used or exposed the respective bits to read a jpeg. This lib was only used to export a jpeg. But still, refactoring our code to work around the need for Jpeglib was the best way to handle this report.


Gigasoft has uploaded version on 9/10/20.

1) Fixed an issue with Pe3do and X and Z Axis line annotations where the axis labels were not positioned correctly when using line annotations to construct a custom axis.
2) Fixed an issue when auto scaling an axis and the range of values resulted in an axis range less than 1e-7.
3) Added support for tool tips and cursor prompt tracking in Polar control.
4) Fixed an issue with Pe3do and order independent DxTransparencyMode and highlighting a data location or annotation.
5) Fixed an issue with WPF interfaces and Pesgo Pego controls and use of CursorMode feature, where pressing Alt key by itself was causing the cursor to disappear.
6) Fixed an issue with the Russian resource DLL.


Gigasoft has uploaded version on 12/3/19.

1) Fixed an issue with table annotations where sometimes the text would overlap. If you added a few spaces to your table annotation text, it likely won"t be necessary and one can tighten the look of the table by removing or reducing such padding.


Gigasoft has uploaded version on 12/01/19.

1) Added support for table annotations to Direct3D Pe3do charts. All locations supported including moveable and pixel located.
2) Fixed an issue when data was located at same pixel as lower or upper edge of axis a hot spot region was not being generated.
3) Fixed an issue with Pe3do Direct3D rendering when using ImageAdjustLeft, ImageAdjustRight, and showing/hiding contour legends changed the visual width-to-height aspect slightly so the image was not exactly square. Now the image is exactly square when using such features.
4) Fixed an issue with Pe3do Direct3D printing where an interim state of chart was flashed to screen while printing.
5) Fixed an issue with Pe3do Direct3D printing where axis labels had a glitch in drop shadow effect when printing and text shadows were enabled.
6) Fixed an issue with ModelessAutoClose setting. We no longer auto close the print dialog as printing to a pdf that opens a window to get filename resulted in closing the print dialog.
7) Fixed issue with RenderEngine = Direct3D, ViewingStyle set to Monochrome, and BorderType set to Shadow, we now hide shadow to be consistent with other Direct3D monochrome bordertypes.
8) Fixed issue with WPF interfaces, changing the quick Color/Monochrome setting within the print dialog was not updating the currently viewed chart as the other interfaces, Winform, DLL, ActiveX, VCL behave.


Gigasoft has uploaded version on 10/1/19.

1) For Pego, fixed an issue where the new virtual data mechanism (9.5) would not chart the first data point when PointsToGraph was non-zero.
2) For Pesgo and Pego, improved the scenario of dragging both edges of the zoomwindow"s zoombox to their respective far edges. Now the chart will undo the zoom state in this case.
3) Fixed an issue with the internal export dialog to handle periods within the name of a subfolder/directory.


Gigasoft has uploaded version on 7/07/19.

1) Fixed an issue with memory usage. 9.5 introduced changes in memory management that were causing out of memory exceptions due to too aggressive predictions in increased demand of memory when arrays grew dynamically in projects that used a large amount of memory. resolves the issue with less aggressive predictions.
2) Fixed an issue with serialization (PEsavetofile) of new feature GraphBmpOpacity
3) Fixed an issue with Setting and Getting the DxZoom property. Setting DxZoom was offsetting by a -7.5 internal factor, but PEvget was not adding back the 7.5 internal factor.


Gigasoft has uploaded version on 6/11/19.

1) Added support for RenderEngine = Direct3D, Pego and Pesgo controls, 2D Bar, BarStacked, BarStackedPercent, and Area plotting methods. fixes Area for double precision data.
2) Added MouseWheelFunction option for Vertical Zoom Only, allowing mouse wheel to only zoom the vertical axis, expanding the HorzAndVertical and Horizontal options.
3) Added property NullDataGapsArea. Set to True to enable the Pego Pesgo Area plotting methods to support NullDataGaps, forming breaks or gaps in the area plot upon null data.
4) Fixed RenderEngine = Direct3D export dpi feature which was not honoring ExportImageDpi and when ExportImageDpi is 0, it now defaults to 96 to match Non Direct3D exports (old Direct3D default was 72).
5) Added properties DeskBmpOpacity, GraphBmpOpacity, TableBmpOpacity, and ZoomWindowBmpOpacity. Now respective background gradients can be combined with background bitmaps and the bitmaps support partial opacity.
6) Added support for MouseWheelZoomEvents = True to also fire ZoomIn event when dragging left or right edge of zoom box in Zoomwindow.
7) Fixed Direct3D support for GraphBmpMinX GraphBmpMaxX GraphBmpMinY GraphBmpMaxY settings when using GraphBmpStyle = Zoomable and the image size was smaller than viewport.
8) Fixed Direct3D DeskGradientStart and DeskGradientEnd colors which had the red and blue components reversed.
9) Fixed Direct3D issue with ShowWireFrame = True combined with surface plotting methods and large surfaces.
10) Fixed VCL interfaces for Pe3do where programmatically sending vertical scroll message was not handling negative scroll positions.


Gigasoft has uploaded version on 3/21/19.

1) Std edition is completed and available, along with Pro edition.
2) New feature to allow randomly setting axis per subset.
Pego, Pesgo
.NET: Pego1.PeGrid.SubsetAxes, Default = Empty, when empty this feature is avoided
OCX, VCL: Pesgo.SubsetAxes
This feature allows setting the axis location (0 - 15) for each subset, individually and randomly.
For example modify demo example 012 with...
Pego1.PeGrid.SubsetAxes(0) = 3
Pego1.PeGrid.SubsetAxes(1) = 2
Pego1.PeGrid.SubsetAxes(2) = 1
Pego1.PeGrid.SubsetAxes(3) = 0
This tells the chart that subset 0 is on axis 3, subset 1 is on axis 2, etc. Reversing the order so the first subset is on the bottom, where normally the first subset would be on top. Historically, one would have to alter the order of subsets to achieve having the first subset on bottom.
One must still set MultiAxesSubsets though technically one only needs to make sure that the total subsets allocated within the MultiAxesSubsets items equals or matches the value of Subsets. There is a test within the chart construction that verifies that allocation of MultiAxesSubsets uses all subsets. As long as when setting SubsetAxes, one uses all axes, the chart will alter MultiAxesSubset items for you to reflect the state of SubsetAxes. This allows changing the numbers of subsets per axis without having to change MultiAxesSubsets, as along as the number of total axes stays the same and each axis has at least 1 subset.
3) Fixed WPF interfaces and a Direct3D D3DImage issue causing a fault in debug mode upon application exit.
4) Fixed WPF interfaces where switching between Direct3D and non-Direct3D RenderEngine settings needed an extra Invalidate.
5) Updated the Asp.Net WebForm example projects.


Gigasoft has uploaded version on 3/18/19.

1) polishes the .Net, MFC, and Access example projects; completes the Delphi and Builder example projects; and fixes a few issues related to new Direct3D Pe3do graph annotations.


Gigasoft has uploaded version on 3/11/19.

1) Version 9.5 has many new features. Please study the "New v9 Features" help file topic: New v9.5 Features


Gigasoft has uploaded version on 7/09/18.

1) The only difference is the ActiveX controls are updated.


Gigasoft has uploaded version on 6/27/18.

1) Fixed an issue with Pego, Pesgo, setting ManualMaxY and ManualMinY with certain amounts containing large numbers of decimals causing overlapping text.
2) Fixed an issue with Pe3do, RenderEngine = Direct2D, the surface plotting method was missing first rows.
3) Improved ContourColorProportions for Pe3do and Pesgo. It is important that when using ContourColorProportions to empty the current state of ContourColors and SubsetColors, and then set number of items in SubsetColors with the same number of items in ContourColorProportions, and then set ContourColorSet = 1. This will produce contour divisions and or contour lines at your desired magnitude locations.
4) Added support for True/False setting of DxPsAntiAliasEdges property with the Pesgo"s contour color Direct3D plotting method.
5) Fixed an issue with QuickStyle feature and GraphGradientStart and GraphGradientEnd.


Gigasoft has uploaded version on 5/7/18.

1) Within the built in export dialog, once a filename exists, changing the export type radio button will now automatically change the file extension to the respective type.
2) Fixed Pesgo 2D contour line plotting method. Lines were not using ContourColorProportions resulting in too many contour lines.
3) Fixed an issue with setting SequentialDataX from default 0 (auto) to 1 (sequential) was causing a problem with showing/hiding subsets.
4) Fixed a problem with wrong pen colors when Subsets greater than 250 combined with ZoomWindow showing all subsets, stressing pen resources.
5) Fixed a problem with RenderEngine = Direct2D, combined with x axis annotations feature showing vertical text. The image"s overall translation was being reset to 0,0 when 0.5,0.5 is needed to produce sharp single pixel wide lines.
6) Fixed DisableStackedPercentMenus which was not properly hiding the menus.
7) Fixed LineSymbolThickness feature which was not controlling the symbol line widths. Set to a value of 3 for 2 pixel widths, Set to 4 for 3 pixel widths, etc.


Gigasoft has uploaded version on 4/7/18.

1) New WPF interface property PersistenceEnabled. Default False, set to True if using chart inside a complex container such as Telerik Rad Dock or other container that destroys and re-creates controls as part of their user interface. ProEssentials defaults to not persist as the chart may contain large amounts of data. It"s recommended to only set this property True if necessary (control is being reset to default 4 data points as part of user interface action.)
2) See the New v9 Features topic within the help system for new information related to version 9.
