Chart.js replace all data
angularjs, chart.js, javascript
Solution
You are creating a new chart, that's why you end up with the old chart behind the new one.
One simple option that I've used: Remove the old chart from the canvas that you are using for the chart:
$('#canvas').replaceWith('<canvas id="canvas"></canvas>');
And now create the chart with the new data in the same canvas
var ctxChart = document.getElementById("canvas").getContext("2d");
window.myChart = new Chart(ctxChart).Line(newdata, options);
Hope it helps!
Problem
im having a issue with Chart.js. Firts, I set a data, and then when a parameter change, I want rebind the entire chart. This work, but its like the chart with the old data still behind the new one. first -> ``` chart.Line(data, options); ``` in a event -> ``` chart.Line(newdata, options); ``` I saw this solution chart.js load totally new data but I dont like this way. Im in a angular directive context, so it's not the best aproach. I tried without results .update( ), .removeData( ), .clear(), .destroy(), etc here its my current directive http://plnkr.co/edit/qn2UUyznonKm6zgEi8FW?p=catalogue Any Idea ?
