Maybe connected to #315. But not fixed in current version.

I got this error too, but noticed that it was because in my .ts I called my data Input() = chartData and in my .html I left it [results] = "single"

This happens when you don't have any data in your "results" array. Instead of crashing out with an error, the chart should just not show anything, like the other charts do. So this is definitely a bug.

For some reason someone closed https://github.com/swimlane/ngx-charts/issues/315, even though this bug was never fixed.

This error exist for more than 3 years now. Will it be corrected some day?
