Description
I'm trying to make a simple Intraday (5m) chart and I'm having a bit of trouble with the xlabels when I don't have a complete dataset:
I'm generating the graph using `mpf.plot(df, ...)`. I've figured out how to make the xlims static from market open to close, but I'd like the labels to be uniformly spaced in 30m intervals and appear even where there is no data (in the morning, only a few xticks are shown). How can I do this?

Research direction
Start at the mpf.plot call and trace how x-axis limits, tick positions, and labels are generated for incomplete intraday data. The work is done when 30-minute labels are uniformly spaced across the market-open-to-close range, including intervals with no data, and the chart behavior is covered by an appropriate test.
