To create a Polar Scatter Plot using Chart.js, you can use the following code:

var ctx = document.getElementById("myChart").getContext('2d');
var chart = new Chart(ctx, {
 type: 'polarArea',
 data: {
 labels: ["Trial 1", "Trial 2", "Trial 3", "Trial 4", "Trial 5", "Trial 6"],
 datasets: [{
 label: "R Values",
 data: [r1, r2, r3, r4, r5, r6],
 backgroundColor: [
 'rgba(27,158,119,0.7)',
 'rgba(217,95,2,0.7)',
 'rgba(117,112,179,0.7)',
 'rgba(231,41,138,0.7)',
 'rgba(102,166,30,0.7)',
 'rgba(230,171,2,0.7)'
 ],
 borderColor: [
 'white'
 ],
 borderWidth: 1
 }]
 },
 options: {
 legend: {
 display: false
 }
 }
});

In this code:

• r1, r2, r3, r4, r5, and r6 are the radial values for each trial.
• The labels property is used to specify the labels for each dataset (in this case, the names of the trials).
• The datasets property specifies the datasets that make up the chart. Each dataset has a label, data points, background color, border color, and border width.
• The options property specifies various options for the chart, such as whether to display the legend.

Please note that you need to replace r1, r2, r3, r4, r5, and r6 with your actual radial values.
