I was following along with the Watchlists Charts video in our lastest version 3 UI and when it came time to change the line color of the point on the chart my UI shows a checkered square in the colour box next to Line color? Sorry I can select a colour but why are they initially black?
Using Watchlists Charts
A checkered square is displayed for a color that is not set or is totally transparent. Lines colors are initially black because the chart uses the point's color which is set on the data point edit page. This used to default to black, it now defaults to blank aka "not set" when you create new data points.
