Hello,
i'm using a chart for .NET
I have a serie and fill this from DataView.
DataView myView = new DataView(DataTable xyz);
((NLineSeries)serie).XValues.FillFromDataView(myView, XXX);
((NLineSeries)serie).Values.FillFromDataView(myView, YYY);
It is possible to make a tooltip for the Datapoints in serie in the chart?
Best Regards,
Alexander

Hello Alexander,
You have to add a tooltip interactivity tool:
nChartControl1.Controller.Tools.Add(new NTooltipTool());
You also have to specify the tooltip format, for example:
series.InteractivityStyle.Tooltip.Text = "<value>";

Hello Nevron Support Team.
Thank You for the answer.
it works!
How can i set the xvalue if i have DateTime on the X-Axis?
I have
serie.InteractivityStyle.Tooltip.Text = " X = ; Y = ; Z = ";
At the moment if i have a DateTime on the X-Axis i have a tooltip
for example: X = 40746,102 ; Y = 123 ; Z = 345
What is the right format of xvalue?
Best Regards,
Alexander

Hello Alexander,
You can set the format the format of the X values like this:
series.XValues.ValueFormatter = new NDateTimeValueFormatter(DateTimeValueFormat.ShortDateLongTimeAMPM);
There are many format options and you can set a custom format string if necessary.
