Thank you so much for developing this RGraph.

I am trying to draw pie chart on the canvas, the data is based on user's select pass week, month, or 6 month, and use ajax to get data from server.

it draw beautiful pie chart, but I tried to clear the canvas by using

  var myCanvas = document.getElementById("chartBlk");
        var context = myCanvas.getContext('2d');
        context.fillStyle = 'white';
        context.fillRect(0,0, myCanvas.width, myCanvas.height);



it covered the chart. it will show the chart again as soon as I click the screen.

Try RGraph.Reset(); inside the () you will need to put the id of your canvas and it should clear it
