I have tried to use the Format.TextFrame2.TextRange
but this does not work as it returns a Microsoft.Office.Interop.Excel.TextFrame2
object that contains text formatting for the specified chart element. It is read only.
I need to set the Secondary Horizontal (value) Axis to white.
Excel.Axis LineAxis = (Excel.Axis)ChartMemory.Axes(Excel.XlAxisType.xlCategory,Excel.XlAxisGroup.xlSecondary);
LineAxis.MinimumScale = 0;
LineAxis.MaximumScale = 1;
LineAxis.MajorTickMark = Excel.XlTickMark.xlTickMarkNone;
LineAxis.Format.TextFrame2.TextRage // but these are read only , and I need to set them
