Chart background color - 03/08/21 09:47
Indicators disappear in scaling mode.Because It is darker than the background.
I suggest chart background color to black.
Or changing the drawing mode in the source code maybe helpful.
SetStretchBltMode(hdc, BLACKONWHITE);

The link is dead. But I don't think a black background will fix disappearing indicators. Can you post a screenshot?

When horizontally scrolled, indicator below changed.
I think it is drawing problem.

Yes. I did not make the chart library, but suppose a bar is not drawn when it's less than a fraction of one pixel.
A different background will not help, but you could try different plot types, like a fat line. That will possibly be drawn.

I tried line chart, it has same problem.
I think you can control the zoom rate to be multiple of 2, then maybe the charts are not distorted.
..., 0.125, 0.25, 0.5, 1, 2, 4, 8, 16, 32, 64, ...
