Hola
Please explain how to highlight the one line among More than one series.
Is there an option like when I clicked a item in legend, the others become blurred at tee chart?

Hello,
one option would be to highlight the series clicked in the legend by making the other series more transparent, e.g.
Code: Select all
private void InitializeChart()
{
for (int i = 0; i < 4; i++)
{
tChart1.Series.Add(typeof(Line)).FillSampleValues();
}
tChart1.ClickLegend += TChart1_ClickLegend;
}
private void TChart1_ClickLegend(object sender, MouseEventArgs e)
{
int index = tChart1.Legend.Clicked(e.X, e.Y);
if(index > -1)
{
for (int i = 0; i < tChart1.Series.Count; i++)
{
tChart1[i].Transparency = 0;
if (i != index)
{
tChart1[i].Transparency = 70;
}
}
}
}
Thank you for tee-chart
You're very welcome
