Canvas.js chart not updating with new data

Question

I'm using CanvasJS to create a line graph based on some numbers coming in from my Myo. When new data comes in, the graph doesn't update. Since I don't populate the graph with initial data points, it stays empty forever.

My code: Here

Answer 1

Try this way.

Lets say: var myChart = new CanvasJS.Chart(...);

Then to update chart data use: myChart.options.data[0].dataPoints = YOUR_DATA_ARRAY; myChart.render();

Worked for me, as I didn't find any 'update' method in documentation.
