Hello Jean,
You can catch the InvalidDataReceived event of the chart. In it you can set the text, font-size and some other customizations for the displayed message. Here’s an example:
protected void UltraChart1_InvalidDataReceived(object sender, Infragistics.UltraChart.Shared.Events.ChartDataInvalidEventArgs e)
{
e.Text = "Some Text";
e.LabelStyle.FontColor = Color. Green;
e.LabelStyle.Font = new Font("arial", 12, FontStyle.Regular);
}
