WPF Chart Library Pricing & Support Comparison

The listed price of a charting library is not the cost. The cost is what you pay over the lifetime of your project — including renewals, support tier upgrades, reactivation fees, and the hidden penalty of losing access to technical help when your subscription lapses. This page breaks down the real numbers for all five WPF charting libraries across multiple team sizes and time horizons.

ProEssentials uses a perpetual license model — one payment, use forever, free unlimited support for life. Every competitor uses annual subscriptions that accumulate year over year. The math is straightforward, but the implications are significant.

ProEssentials Support: Free, Unlimited, from the Developers

ProEssentials support is free, unlimited, has no ticket cap, no tier system, no expiration, and is provided directly by the developers who designed and built the charting engine. This is not a call center. This is not a tier-1 agent reading from a script. When you email a question, the person who wrote the rendering code reads it and responds.

There is no gatekeeping. You do not need to provide a minimal reproducible example before someone will look at your question. You do not need to search forums first. You do not need to classify your issue by severity level. You ask, they answer.

This support continues for the lifetime of the version you purchased. If you bought ProEssentials v10 in 2024 and email a question about it in 2030, you get the same quality of response. No renewal required. No subscription to maintain. The support commitment is permanent.

SciChart Support: 10 Tickets, Tiered Access, Fair Usage

SciChart includes Standard Support with 10 tickets per year per license as a soft limit. Their blog describes support as their 'biggest cost' and notes they receive roughly 3,000 tickets per year, adding that 'not all are needed' and 'some are user error.'

Ten tickets per year sounds adequate until you're integrating a complex library with MVVM bindings, 3-D rendering, and resampling behavior. During a typical first-month integration, a development team can easily generate 10 questions just learning the DataSeries architecture and ResamplingMode behaviors.

SciChart also offers a No-Support license tier at roughly 30 % lower cost. The existence of a no-support option tells you something about how the vendor views support — it's a cost they'd prefer to offload, not a relationship they want to build.

For teams that need more, Priority Support is available at premium pricing with unlimited tickets, a dedicated Microsoft Teams channel, and bookable video calls. Consultancy Retainers provide unlimited support plus development work at custom pricing.

LightningChart Support: As Few as 2 Tickets Per Year

LightningChart has the most restrictive support ticket limits in the WPF charting market. Non-Perpetual (subscription) licenses include just 2 tickets for a 1-year term or 4 tickets for a 2-year term. Standard Perpetual licenses include 10 tickets for 1-year or 15 for 2-year terms.

With over 1,500 properties in the API, limited online code examples (examples are only available inside the downloaded SDK, not on the public website), and no AI code assistance, two support tickets per year is effectively no meaningful support. A developer encountering their first SampleDataBlockSeries configuration issue has already used one ticket.

Premium (Enterprise) support — available only at custom-quoted pricing — includes unlimited tickets and one 30-minute video call per year. One call. Thirty minutes. Per year.

Syncfusion & DevExpress: Generalist Support for 120–145 Controls

Syncfusion and DevExpress both provide support as part of their subscription. The key limitation is not ticket count — both offer reasonable volume — but specialization. The engineer answering your charting question also supports grids, schedulers, ribbon controls, PDF viewers, and 100+ other components.

For common scenarios — binding a chart to a DataTable, changing axis labels, adjusting colors — generalist support is adequate. For advanced charting questions — GPU rendering behavior, large-data performance, custom annotation placement, multi-axis synchronization — a generalist may not have the depth of knowledge that a dedicated charting team provides.

Syncfusion's Community License (free for companies under $1M revenue) provides community forum access only — no direct support tickets. If your company grows past $1M, the community license is revoked and you must purchase at $995–$2,495 per developer per year immediately, including retroactive compliance. This creates a pricing cliff that can surprise growing startups.

The Bottom Line on Pricing and Support

ProEssentials' pricing model is unique in the WPF charting market: one-time perpetual payment, unlimited developers (National license), zero support cost, support that never expires, and direct access to the developers who built the engine. No other library offers all five.

SciChart offers strong technical capability but at 7× the 5-year cost of ProEssentials for a 10-developer team, with support capped at 10 tickets per year and a fair usage policy that throttles heavy users. LightningChart's 5-year cost reaches $288,750 for 10 developers with as few as 2 support tickets per year at the subscription tier. Syncfusion and DevExpress offer lower prices but with generalist support covering 120–145 controls where charting is a small fraction of expertise.

For any team evaluating charting libraries, the pricing question is not 'what does year one cost?' It is 'what does this cost over the life of our project, including the support we will inevitably need?' On that measure, ProEssentials is the clear leader.
