How to use SetDashArray in ChartLineStyle

DashArray you pass in an array with the pattern to follow.  It can be as short or long as you like.  It will follow the pattern you specify, if you specify 3 segments, then it will repeat those 3 segments.  If you specify 1 segment, it will repeat this 1 segment.  You must specify BOTH segment length and gap length or else you will get only a solid line.

For example, this is a little bigger than the standard dash:

xLineStyle.LineStyle.SetDashArray (Array(5, 2))

this is the pattern:

SetDashArray (Array(Segment1 width, first gap width, Segment2 width, second gap width, etc, etc))

These are also valid:

xLineStyle.LineStyle.SetDashArray (Array(2, 1, 5, 2))

xLineStyle.LineStyle.SetDashArray (Array(2, 1, 5, 2, 8, 3))

Here is code:

    Dim xLineStyle As ChartLineSeriesStyle

    Dim nThickness As Integer

    

    nThickness = 5

    

    Set xLineStyle = New ChartLineSeriesStyle

    xLineStyle.LineStyle.DashStyle = xtpChartDashStyleCustom

    xLineStyle.LineStyle.Thickness = nThickness

    xLineStyle.LineStyle.SetDashArray (Array(5, 2))

    Set ChartControl.Content.Series(0).Style = xLineStyle

Hope this helps
