You cannot change only the FontHeight, because you are only allowed get the FontHeight or FontWidth to consult their values. Therefore, if you want change the size (height and width) of font you must assign a value to font size as do in next lines of code:
public Form1()
{
InitializeComponent();
InitializeChart();
}
private void InitializeChart()
{
tChart1.AfterDraw += new PaintChartEventHandler(tChart1_AfterDraw);
}
void tChart1_AfterDraw(object sender, Steema.TeeChart.Drawing.Graphics3D g)
{
g.Font.Size = 25;
g.TextOut(100, 150, "TeeChartFor.Net");
}
I hope will helps.
Thanks,
