For a radar chart, usually you will want to show a label on each point of the chart, so we include an array of strings that we show around each point in the chart. If you do not want this, you can either not include the array of labels, or choose to hide them in the chart options.

For the radar chart data, we have an array of datasets. Each of these is an object, with a fill colour, a stroke colour, a colour for the fill of each point, and a colour for the stroke of each point. We also have an array of data values.

For each area, you can give a “title

Instead of assigning a real color to the fillColor, strokeColor, pointColor and/or pointStrokeColor variable, you can assign a function that returns a color. See chapter “Color Function” later on.
