I'm using 12.10.1.12
I have not set any rendering settings. Are there any others to set besides TextRenderingHInt?
Adding this:
nChartControl1.Settings.TextRenderingHint = System.Drawing.Text.TextRenderingHint.ClearTypeGridFit
Dim charttitle As NLabel = New NLabel()
nChartControl1.Panels.Add(charttitle)
charttitle.Text = "Chart Title"
using Arial Font, size 62pt
Produces the attached image.
the image dimension is 1280x960
