Hi Paul,
The reason you were getting that error is because unless you
specify otherwise, ax.bar will make the bottom of the bars at 0 -
which isn't an allowed date, hence the error. Change your bar
line to this (I also added align='center', but you can remove it
if you want):
Aha, OK that

bars = self.subplot.bar(self.final_dates, top-bot, bottom=bot, align='center')
I get the error:
TypeError: unsupported operand type(s) for -: 'list' and 'list'
Because I am trying to subtract the bots list from the tops list.
In the example code I gave,
just make a numpy array out of your two lists, and you'll be able
to subtract one from the other.
import numpy as np
top = np.array(top)
bot = np.array(bot)
Thank you, Paul. That worked and I'm now able to display bar charts.
I appreciate it.
Best,
Che

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

Just a thought, are you trying out the new legend code?
I don't know if I am or not. But these problems are prior to any code
regarding the legend.
Could you do a print of the type for bars?
When I write it as just bars without the comma it is:
bars type = type 'list'
If I write it with

I know the 2nd problem is that a dictionary cannot have a mutable
object like a list as a key. But previously, as I said, I was able to
call line, (with the comma) and it would work. In fact, line, with a
comma gives this type:

3) I am getting just hammered with the following error *a lot* in date
plotting lately:
ValueError: ordinal must be = 1
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 out
