Hi,

How do I modify the axis range when using a date/time scale type, after setting the chart scale type with SetArgumentScale(xtpChartScaleDateTime) ??

SetMaxValue/SetMinValue only takes a double as argument, even when I pass a CTime::GetTime() value cast to a double value the scale only reads 'Invalid date/time'.

I try to do this on a StepLine chart type in order to add some spacing on each side of the end data points.

Never mind....

After changing to OleDateTime objects the conversion to double works out better and I can change the axis range as desired.
