ChartLength Property
Syntax
CWGraph.ChartLength
Data Type
Purpose
Specifies how many points the graph stores when charting before it deletes old data.
Remarks
Set this property to 0 to store only enough points to fill the plot area.
If the AutoScale property is enabled on the x axis, the system does not recalculate the chart length.
Only the ChartY method supports automatic chart length calculation. The ChartXY and ChartXvsY methods do not.
If you change the x-axis range (the XInc parameter) between calls to ChartY, there might not be enough data to fill the plot area.
