Generates an Impulse-response style chart with optional point-marker in code. The FastImpulseRenderableSeries can be used to render an XyDataSeries (which contains one X-point and one Y-point), XyyDataSeries (renders Y values), XyzDataSeries, HlDataSeries and OhlcDataSeries(renders Close values).

Impulse Chart can be used to visualize Digital Filter responses, or scientific charts, for instance, mass spectra.

Tip!

You can add optional data-point markers to a impulse series using the PointMarker API. This is very performant and uses the same bitmap rendering as our Scatter-Charts.
