I tried to create pie chart and dough chart using chart.js. But I'm getting only one chart, though I entered input for both the chart in my code.

Edit: edited the code.

        let colors = [];
  
        for (let i = 0; i < length; i++) {
          colors.push(pallet[i % (pallet.length - 1)]);
        }
  
        return colors;
      }
      var xValues = ['Multimeter', 'UniBox', 'Toby', 'Cables', 'Test'];
      var yValues = [2, 100, 223, 84, 197];
      var barColors = getColors(xValues.length);
  
      new Chart("myChart1", {

        data: {
          labels: xValues,
          datasets: [{

How one can insert two inline charts on the web page? I'm an absolute beginner in chart.js.

Your script tags seem to be duplicated, I'm not sure if this is intentional but you're overshadowing any functions and vars declared in the first script tag with the second script tag.

Regardless, the problem here is that you're loading two charts with same ID on one canvas.

Set the name of your second chart to myChart2 and add another canvas with myChart2 as ID:

new Chart("myChart", {
...

new Chart("myChart2", {
...

and for the canvas:

<canvas id="myChart" width="90" height="90" style="width:100%;max-width:650px"></canvas>
<canvas id="myChart2" width="90" height="90" style="width:100%;max-width:650px"></canvas>

That should load both charts and inline can be accomplished through css using flexbox or inline-block display.
