Example 138: Scientific Graph showing real-time 6

1//! Chart holds 4M points.  Data is fed into data arrays at current data index.
2//! This type of real-time allows best method for incrementally updating large quantity of data.
3//! This example uses Direct3D, historically with non Direct3D this type of implementation
4//! would become slower and slower over time as data increased.  With Direct3D this chart will not
5//! slow down over time and though this example's timer is at 1 second, it could be faster.
