Visible Series in Chart

[JohnCZ]

Hi there,
I was wondering if it is possible to hide/visible the series in Chart Object.
I tried it with simple code but still is not working.

Code: Select all

if (Globals.Tags.Visible_Curve1.Value = 1)
			{
				Chart1.Series["Series"].Visible = true;
			}
or

if (Globals.Tags.Visible_Curve1.Value = 1)
			{
				Chart1.Series["Series"].Enabled = true;
			}

Yes, but you access via the Curves not Series.

like

Code: Select all

// with name
Trend1.Curves["Curve 1"].IsVisible = false;

// or index

Trend1.Curves[0].IsVisible = false;

You can toggle them like this

Code: Select all

void Button1_Click(System.Object sender, System.EventArgs e)
{			
	Trend1.Curves[0].IsVisible = !Trend1.Curves[0].IsVisible;
}

Best Regards

Thanks Edmund,

I use this code for trend viewer. What I mean is that I have a chart graf (Chart types= line) not trend. This code is working for Trends.

Hi there,

Thanks I already used it as no-friendly solution. But customer doesn't wanted because the previous chart stay there. This script only active/inactiv the chart. He wants to have it as in trends, so we did three charts object and used tags to visible them.

Best regards
