Hi.
Found incorrect code in the Radar sample. Typescript Intellisense pointed this out.
Config.Data.Dataset has dict keys label, backgroundColor, borderColor, pointBackgroundColor, data
When the Radar chart is setup, it uses dict keys label, backgroundColor, borderColor, pointBorderColor, data
pointBorderColor should be pointBackgroundColor.
Saw other questions about Radar colors. Not sure if it is related. They could have started from the example.
