Changing data in Chart.js, strategies for modifying data after chart creation!

Apologies if this question seems basic. The challenge I am facing is that I need to utilize the same data for multiple charts, but with slight variations in options for each chart. The data is as follows:

    var data = {
      labels: freq,
      datasets: [{
        borderWidth:1,
        label: "ADC Visualization",
        fill: false,
        lineTension: 0,
        backgroundColor: "rgba(75,192,192,0.4)",
        borderColor: "rgba(75,192,192,1)",
        borderCapStyle: 'butt',
        borderDash: [],
        borderDashOffset: 0.0,
        borderJoinStyle: 'miter',
        pointRadius: 1,
        data: mag
     }]
    };

Now, let's say I want to use this data but with the pointRadius set to 5 for a specific chart. I am aware that I can do the following to set the data:

var myLineChart = Chart.Line(mycanvas,{
  data:data
})

However, I am looking to set the pointRadius to 5 instead of 1. Essentially, I want to achieve something like this:

var myLineChart = Chart.Line(mycanvas,{
  data:data,
  datasets: [{ pointRadius: 5 }]
})

Is this possible to accomplish? Thank you!

Answer №2

Absolutely, it is definitely possible to accomplish this task. Simply integrate the new field into your existing data object.

Here is a step-by-step approach:

// initialize the first chart
var myLineChart = Chart.Line(mycanvas,{
  data:data
})
// create a new dataset
var newData = data;
newData.datasets[0].pointRadius = 5;
// render the second chart
var myLineChart2 = Chart.line(mycanvas2,{
  data:newData
})
