单击jchartfx中的点打开弹出窗口

Question

I want to open the popup on click of points in jchartfx to display the detail information about that point. How can i pass the unique id to display the detail information dynamically?

I'm not sure about performing it on click , but the jChartFX samples include a downloadable example (with some code ) of doing this via tooltips (ie on hover).

Basically, you need to handle the 'gettip' event:

chart1.on("gettip", onGetTip);

The handler should create a div with the content for your tooltip:

function onGetTip(args) {
    divInTooltip = document.getElementById('tipChartInfo');
    args.tooltipDiv.appendChild(divInTooltip);
    args.replaceDiv = true;
    var dataPoint = args.getPoint();

    // Custom code based on the data point...
    ...
}

Regarding your specific question, the data point that the tooltip relates to is available via args.getPoint() .
