The problem of the Brin belt indicator
Author: flyju, Created: 2020-04-23 13:53:09, Updated: 2020-04-23 17:18:49I can't draw a Braille indicator in a chart because I can't draw a Braille in a graph with a line library or a chart.
The resulting Brin array can be logged out, but it's going to have about a dozen nulls in front of it.

flyjuI already know that the empty value is the reason why I thought the previous data was insufficient to calculate, but the problem is that I can't figure out why it's not showing.
The Little DreamThe printed value is null, the actual value is NaN, and filtering these invalid data values when drawing the graph is fine.
