Add x-padding for the chart

[Ragu nathan]

Hi,

I have a chart with multiple y-axis. The data points are very large. So the same x-position will have multiple data points.

If the first and last x-position has multiple points, it’s difficult to view the chart points. It’s almost rendered over the y-axis. Is there any option to add some padding between the y-axis line and the chart points?

I have sample jsfiddle I want to add some padding between the y-axis line the data points. How can I achieve this? Is there any option in CavasJs to do this?

@ragu1991nathan,

Based on the minimum x-value among all the data series, you can set the minimum for X-axis to add some space between the Y-axis line and the first datapoint as shown in the code-snippet below,

function setXMin() {
  var xMinValue = 0;
  for(var i = 0; i < chart.options.data.length; i++) {
    xValues.push(chart.options.data[i].dataPoints[0].x);
  }
  xMinValue = Math.min(...xValues);
  chart.axisX[0].set("minimum", xMinValue - chart.axisX[0].get("interval"))
}

Kindly take a look at this updated JSFiddle for an example on the same.

Please refer to this forum thread for more information & examples.
