How to show BAr graph rather than line graph in High Stoch Chart


How to show BAr graph rather than line graph in High Stoch Chart

Hope this helps After playing around with the chart I found the following solution which can be seen in the demo below:
code :
$('#container').highcharts('StockChart', {

            chart: {
                type: 'column'
            },

            rangeSelector: {
                allButtonsEnabled: true,
                selected: 2
            },

High Chart inserting data from arrays into line graph

wish helps you If you can alter the function, the you should prepare data in the right format. Sth like the sample data in your example. If you cannot, then make a for loop to prepare the data. Sth like this:
code :
   xy= [];
   for(var i in x) {
      xy[i] = [x[i],y[i]];
   }

With these it helps You need to find the intersection points of the series - and having coordinates you can plot a line (line with an arrow) and a text - both can be rendered with Renderer.
code :
  chart: {
    type: 'column',
    events: {
      load: function() {
        const points1 = this.series[2].points;
        const points2 = this.series[3].points;

        const intersection = [];

        for (let i = 1; i < points1.length; i++) {
          const intersect = getLineIntersection(points1[i - 1], points1[i], points2[i - 1], points2[i]);

          if (intersect) {
            intersection.push(intersect);
          }
        }

        const xAxis = this.xAxis[0];
        const yAxis = this.yAxis[0];

        intersection.forEach(coord => {
          const text = this.renderer.text('break point', -999, -999).add();
          const anchorX = xAxis.toPixels(coord[0]);
          const anchorY = yAxis.toPixels(coord[1]);

          const connector = this.renderer.path([
            'M', anchorX, anchorY,
            'L', anchorX - 5, anchorY - 100
          ]).attr({
            stroke: 'black',
            'stroke-width': 1,
            zIndex: 99
          }).add();


          text.attr({
            align: 'center',
            x: anchorX - 5,
            y: anchorY - 110,
            zIndex: 99
          }).css({
            color: 'black',
            fontSize: '14px',
            fontWeight: 'bold'
          });
        })
      }
    }
  },

I hope this helps you . Well very new to chart.js. having some doubts on this and can't figure out how. , After you've generated graph by,
code :
const canvasmixedBarLine: any = document.getElementById('mixedBarLine');

const ctxmixedBarLine: any = canvasmixedBarLine.getContext('2d');

const mixedBarLine = new Chart(ctxmixedBarLine, {});
ctxmixedBarLine.globalCompositeOperation = 'destination-over';
Graph monthly and daily data in bar chart and line chart in the same graph

will help you When using line/column charts Excel only cares about the number of data points for the x-axis (not their x-values). The reason you're having difficulty is because your two series have different numbers of points (i.e. 365 vs 12)
To get around this you need to make them match by spanning Series 2 across 365 data points.
Chart Js update legend boxes of graph with graph line style

Chart Js update legend boxes of graph with graph line style

This might help you There's a legend option called "usePointStyle" that should match the legend style to the style of the graph point.
code :
legend: {
  labels: {
    usePointStyle: true
  }
}
