How to show tooltip on MS Chart

Question

I am using MS Chart control to draw graphs on Winform.

I want to show the current (x,y) Value as tooltip on Mousedown on chartarea.

How do I do that?

Answer 1

From the chart samples (Samples Environments for Microsoft Chart Controls)

// Set ToolTips for Data Point Series
chart1.Series[0].ToolTip = "Percent: #PERCENT";

// Set ToolTips for legend items
chart1.Series[0].LegendToolTip = "Income in #LABEL  is #VAL million";

// Set ToolTips for the Data Point labels
chart1.Series[0].LabelToolTip = "#PERCENT";

// Set ToolTips for second Data Point
chart1.Series[0].Points[1].ToolTip = "Unknown";
