I have time series data shown in Area chart. Because there many data points the X-Axis is not showing up correctly.
There does not seem to be a way to rotate the axis labels for CatgorySeries .
I don't like having several rows of labels below X-Axis
What would be the best way to format this axis?
See screenshot for example
This particular chart always shows data pointing down
If you want to rotate the axis labels you can do so by setting labelOrientationAngle property on the axis. Note, that this property isn't available on IGCategoryAxisBase class and the axis needs to be case to an appropriate type.
((IGCategoryXAxis*)series.xAxis).labelOrientationAngle = 45;
By default, series use y=0 as reference value, so negative values in an area series are plotted downwards. You can set yAxis.referenceValue to be negative if you want to 'inverse' your area.
