First of all, thanks for sharing such a magnificent and mature library. The financial plot brought my special attention to it. In principle everything is fine with it, except one problem:
The test data that you use is unrealistic in the sense that they go through the whole week, including the weekend, while in reality during the weekends the markets are closed and no data is being fed. Feeding “dead” data on the other hand would confuse technical indicators, because they average price over time, and could not provide realistic readouts anymore. The real data generates the following gaps during weekends:
Getting more into detail, daily bars are not the only granularity available, because it may go even down to 1 minute. Plotting this on the Financial plot would create wide gaps in data because of weekends.
So the question is: would there be a chance of hiding the weekend data somehow? I recognize that the library is mainly a scientific library, where the X axis is always continuous, and solving my problem would require the axis' manipulation. Is this really possible at all?
