  Position of DataLabels

Hi Peter,

I have a simple polar-chart. (see Attachment)

I've added a linelayer to the chart:

Call c.addAreaLayer(AnsMinVal, &HC9F47D35, "Anforderung")
set layer = c.addLineLayer(AnsVal, &HD85A0C, "Ergebnisse (eigene)")
call layer.setLineWidth(2)
call layer.setDataLabelStyle("arial.ttf", 9, &H888888)
call layer.setDataLabelFormat("{value|1}")

But the position of the labels disturbs. Is it possible to position the labels outside the linelayer? Like the red xxx in the example? So that the numbers do not cover the data points or the line?

Thanks for a short help.

Hi Björn,

By default, the labels will be put on top of the data point. For your case, may be you can try to use PolarLayer.addCustomDataLabel to configure different positions based on the "angle" of the data point. For 12 labels, may be you can try (in VB/VBScript):

alignment = Array(cd.Bottom, cd.BottomLeft, cd.Left, cd.Left, cd.Left, cd.TopLeft, cd.Top, cd.TopRight, cd.Right, cd.Right, cd.Right, cd.BottomRight)

For i = 0 To 11
    Call layer0.addCustomDataLabel(i, "{value|1}", "arial.ttf", 9, &H888888).setAlignment(alignment(i))
Next

Hope this can help.

Regards
