@johnbdesanto Please let me know if the demo plots above looks okay to you. The time axis seems like there might be too much ticks... currently it defaults to 25 ticks.. maybe I need to reduce this.

[johnbdesanto]

The ticks on the x-axis are a little dense. If there's a way to reduce the ticks to the 15-20 range, I suspect that that might be easier to parse the axis labels.

I was concerned that the plot may be colorblind-unfriendly, but after checking with coblis it seemed fine.

That's what I thought. I actually made the underlying function super easy to adjust the ticks, so yes we can reduce it. I set to 15 and this is what I get:

Thanks for checking on that. I haven't really thought about the colors. I will change that to make sure it's the most colorblind friendly!

Really appreciate your input @johnbdesanto 😄

Updated demo after n_ticks = 15 and now using a more colorblind friendly colors

Couple of inline comments and looks like some missing tests.

Thanks! I'm skipping tests for now. Trying to get this out for user testing atm
