Tag: double.NaN

Hi,

When rendering a FastLineRenderableSeries, there are line segments missing both before and after a double.NaN Y value. This makes sense for a regular line series, but for a step line series (where IsDigitalLine=True), why isn’t the line segment preceding the NaN being drawn? When plotting (for example) financial prices over time, the missing line before the NaN gives the impression that a price didn’t exist for that period, which is incorrect.

I’m looking at the IterateLines method in FastLinesHelper. Even though the method has an isDigitalLine parameter, it isn’t checked during the handling of a NaN value. Is this an oversight?

Thanks very much,

Graham.
