Dear Sirs,
we plotted line chart by using NVD3-chart format. As mouse moving on chart line path,
we want to add mouse dblclick event to get X-coordinate value and copy it to clipboard.
How to handle this ? Please give us ideas. Thank you.

You have to check NVD/Javascript documentation...
In ChartNVD3.cshtml, you have already a Click handler that works only for Pie charts.

                   if ((@chartId).pie) {
                        (@chartId).pie.dispatch.on("elementClick", function (e) {
                            var nav = @(chartId).navigations[e.data.x];
                            if (nav) showPopupNavMenu(e.event, nav, true);

Check also the other chart types, they are well documented.
