[Chartjs]-Chart.js chart distorted with fixed width

by

3👍

for me the problem was that graph was setting for itself height that was bigger that I myself had set to canvas.

my solution was:

  1. I removed all height setups for canvas (css and tag attribute)
  2. Created container tag for the canvas and set height to it
  3. in chart options added:
      responsive: true,
      maintainAspectRatio: false,

in the example in the question problem was in css:

canvas {
  left: 0px;
  height: 300px !important;
}

i would change it to:

.tds-hor-scroll {
	overflow-x: auto;
}
.tds-chart-inner {
  min-width: 850px;
  height: 300px;
}
<div class="tds-hor-scroll">
	<div class="tds-chart-inner">
	  <canvas id="tds-chart-mem"></canvas>
	</div>
</div>
