Chart.js canvas resize


In (Android WebView HTML5 canvas error) i posted a question regarding plotting graphs using Graph.js library. The problem i have now is that if i call the function to plot the graph multiple times, the canvas resizes every time. Each time the graph is redrawn to the same canvas, its size also changes. I also tried setting the size of the canvas but without success.

What could be the reason? Why does the canvas resize every time?


Solution

  • I had a lot of problems with that, because after all of that my line graphic looked terrible when mouse hovering and I found a simpler way to do it, hope it will help :)

    Use these Chart.js options:

    // Boolean - whether or not the chart should be responsive and resize when the browser does.
    
    responsive: true,
    
    // Boolean - whether to maintain the starting aspect ratio or not when responsive, if set to false, will take up entire container
    
    maintainAspectRatio: false,
