How to increase the link size when there is a text on it.The link text and link are getting overlapped.
Please have a look at the picture
How did you define the TextBlock that you are using on the link? Is it something like:
<TextBlock Text="{Binding Path=Data.Text}" go:LinkPanel.Index="-1"
go:LinkPanel.Offset="NaN NaN" go:LinkPanel.Orientation="Upright" />
If so, then you just need to increase the spacing between the layers. If you are using TreeLayout or LayeredDigraphLayout, increase its LayerSpacing property.
