Matplotlib how to collapse time gaps in datetime axis without changing axis from datetime to string?

I'm writing a stock trading application, and I want to show a chart with price data and multiple technical indicators plotted on the same graph.

I'm using the twinx() function for plotting multiple indicators along with price.

I don't know how to handle the time-gap on the chart when trading is closed. I have read several answers on SO and other places and they all say to convert datetime to string on the axis where I want to close the gap.

But this is not an option for me because for the multiple indicators I'm calculating on the spur of the moment and they have a shorter date-time range than the price data. It is convenient to just pass the datetime values and have the indicators plotted starting from the far right of the chart.

Is there a way to accomplish this? Any help would be appreciated.

Thanks in advance.

You’re going to want to look at [broken axis plots](https://matplotlib.org/3.1.0/gallery/subplots_axes_and_figures/broken_axis.html) – William Miller Jan 24 '20 at 10:27

@WilliamMiller I checked out broken axis plots and found [this package](https://github.com/bendichter/brokenaxes) which might be an easy way to do what I want. If it works, I will post it as an answer. Thanks v.much again for the pointer. – nparabz Jan 24 '20 at 11:22
No problem, I’m glad I pointed you in the right direction – William Miller Jan 24 '20 at 11:24
