Looks like the clear function is not working for ajax request. I have the following in success body of my ajax, and my result does not clear and another chart draw on it again and again.

function MovePie(obj) {
                         RGraph.Effects.Animate(obj, { 'chart.radius': 30, 'chart.centerx': 60, 'chart.centery': 60, 'frames': 5 });
                     var line = new RGraph.Line('canvasLast24', mvOrder, hbOrder, allOrder)
                 .Set('curvy', true)
                 .Set('curvy.tickmarks.fill', null)
                 .Set('linewidth', 2)
                 .Set('chart.gutter.left', 30)
                 .Set('hmargin', 5)
                 .Set('labels', label)
                 .Set('tooltips', label)
                 //.Set('tickmarks', 'circle')
                  var pie = new RGraph.Pie('canvasLast24', [oneWeekMV, oneWeekHB])
                 .Set('centerx', 300)
                 .Set('centery', 150)
                 .Set('radius', 125)
                 .Set('exploded', [5])
                 .Set('strokestyle', 'rgba(0,0,0,0)')
                 .Set('shadow', true)
                     RGraph.Effects.Pie.RoundRobin(pie, null, MovePie);

Hi there,

It sounds like you need to clear the object registry. As Arnaud said you can use the ObjectRegistry clear function passing it the canvas ID or the canvas itself (as retrieved from document.getElementById() ) or you may also find that resetting the canvas works:
