Reinitialize a trend
Posted: Tue Apr 10, 2012 5:28 am
Hi. I need to reinitialize a trend, deleting the old values of the curve when a user logs out. Is it possible? In which way?
Thank you!

There is no way to clear the trend lines on the screen. You can start and stop individual trend lines and you can hide or show the trend line control.
Code: Select all
public partial class Screen1
{
static ICurve aCurve;
void Button1_Click(System.Object sender, System.EventArgs e)
{
//Stop aCurve from being updated
this.Trend1.Curves.Remove(aCurve);
}
void Button2_Click(System.Object sender, System.EventArgs e)
{
//Start aCurve up again
this.Trend1.Curves.Add(aCurve);
}
void Screen1_Opened(System.Object sender, System.EventArgs e)
{
//Which curve to start/stop
aCurve = this.Trend1.Curves[0];
}
}
