Hello,

Consider we have drawn a line graph with 5 points.

Can we able to drag the datapoint using mouse and change its location in the graph?

Can we make the graph from | to _ by just draging the graph data points by mouse?

Hi,

Note that in the above example you can drag datapoint along y-axis only. If you want to drag the datapoints along both x-axis and y-axis then you can make use of XValue of PlotArea event argument. Please check out the code below.

void PlotArea_MouseMove(object sender, PlotAreaMouseEventArgs e)
{
_yValue = e.YValue;
_xValue = Convert.ToDouble(e.XValue);
}

void PlotArea_MouseLeftButtonUp(object sender, PlotAreaMouseButtonEventArgs e)
{
if (_dataPoint != null)
_dataPoint.YValue = _yValue;
_dataPoint.XValue = _xValue;
}
