Hi, I'm new to mpl and want to learn date plotting. Would like to start
with the demo, but date_demo1 won't run for me. (My specs: winXP, Python
2.5, matplotlib 0.9.0, numpy 1.0, and yes was connected to the internet when
I ran it). I just copied into IDLE and saved it and got this error:
This is really basic stuff but I had some problems navigating in the
matplotlib website (*if anyone is interested, I'll list those issues at the
end). I want to simply plot dates. After reading the tutorial, I just
don't understand how to do it.
I will have lists of dates in the format like
= DateFormatter('%Y-%m-%d')

No, plot_date is available as an axes method. Most pylab plotting

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
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
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

Hello!
I am also using two axes in a plot and want to be able to pick the lines of
both axes.
So far I used MPL 0.99.3 and a button on my interface to change the z-order

I'm not sure if this is going to work to solve an issue I'm having, but I'd
like to try it before asking a much more complex question. I have a
function, loose_autoscale_view(), that is based on the autoscale_view
function in mpl but allows margin arguments to push the margins out a bit
more.
I need to get the bboxes for time-range bars (matplotlib.patches.Rectangle
objects) on a bar plot for a custom autoscaling function.
Right now, I get them like this, where rectObj = a bar and bboxes = a list
of bboxes:
bboxes.append(rectObj.get_path().get_extents())
print 'bboxes is: ', bboxes
I should add, I can see that (I think) this needs to use a transform to get
it in data coordinates, because if I do this to each rectObj (each bar):
trans = rectObj.get_patch_transform()
print 'trans is: ', trans
I get:
trans is: BboxTransformTo(Bbox(array([[ 734189.52541214, 730844.

Because you have a py2exe'ed program, I suspect that whoever packaged the
program should be the one to modify that program to choose its axes limits
more robustly in order to avoid the warning message.
Maybe I have been unclear. I am the sole developer of this
application, and I occasionally

I think I fixed a similar bug at some point but I'm not sure if that
