How to redraw chart

    I am doing dymamic chart , all my points are in array linegraph[“test”] ,

    data: [

    type: “line”,
    dataPoints: linegraph[“test”] ,
    axisYIndex : 0,
    markerBorderThickness: 0.9,



    What I need is to empty the linegraph[“test”] , modify with new values and redraw.

    so I am doing linegraph[“test”] = [];
    then adding my values to linegraph[“test”] then running chart.render();

    but chart is not rendering , even though linegraph[“test”] has all the values.

    How do I force canvas js to reread the linegraph[“test”] ?



    Can you please create a JSFiddle reproducing the issue you’re facing and share it with us so that we can look into the code, understand it better and help you out?
