Thank you, Paul. That worked and I'm now able to display bar charts.
I appreciate it.
Best,

OK, I made up a small runnable sample to show this with bar(). (Using
code that someone else wrote[1]). This code runs when using
plot_date(), but if you comment that

I usually do this for line graphs with markers:
line, = self.subplot.plot_date(dates,data)
along with some keywords to tweak the plot. I then add line to a
dictionary to keep track of it:
self.line_to_data_dict[line] = self.activity
But today I tried this with a bar chart, just changin
