I have an issue with LogarithmicNumericAxis and FastColumnRenderableSeries. If replace one of FastLineRenderableSeries with FastColumnRenderableSeries in Logarithmic Y-axis SciChart example you’ll receive empty chart (the same behaviour in my application). Only if disable logarithmic on both x and y axis the columns (and lines) appears. How to make LogarithmicNumericAxis with columns work?
The reason you’ve seen empty chart is next: FastColumnRenderableSeries has property ZeroLineY, and it is 0 by default. When we try render the series, LogarithmicDoubleCoordinateCalculator try to get logarithm of 0, which is actually NaN, and therefore range for rendering is invalid.
Please try to set ZeroLineY different from 0. For example :
<s:FastColumnRenderableSeries ZeroLineY="1" FillBrush="#1964FF" SeriesColor="Blue"/>
Hope this helps.
Thank you for your reply. But if I replcace a FastLineRenderableSeries in the Logarithmic Y-Axis example with your example string (FastColumnRenderableSeries ZeroLineY=”1″…) I still get the empty chart.
