I would like to control the y axis of a plot. The following code does
exactly what I want it to! On my linux computer it sets the y axis
limits to 18.0 minimum, 58.0 maximum, plots some points on y=x, provides
ticks at 20,30,40,50 and horizontal tick lines that intersect the
plotted points.
All very good, but if I change the upper y axis limit to 54.0,
(ax.set_ylim(18 .0, 54.0)), it fails, plotting the ticks at some strange
values.
Ultimately I want to uncomment the set scale to log and use this to
label semi log plots that by default are only labeled on powers of 10.
My data falls within one decade so I don't want the full 10-100 limits.
I'm rather new at matplotlib so if I'm making trivial errors please feel
free to criticize.
Thanks
Dick C

I'm playing around with matplotlib for the first time. I'm trying to
make a very simple histogram of values 1-6 and how many times they
occur in a sequence. However, after about an hour of searching I cannot
make the histogram stay within the bounds of the grid lines.
Here is my example:

x_values=
pylab.hist(x_values,6)

I am trying to automate the generation of scatterplots in matplotlib.
The problem of where to put the labels is known as 'point-feature

Hi,
I'm trying to create a small GUI program where I can do plots using
Matplotlib. I've been trying to borrow code from the examples at the
matplotlib website, but I can't get it to work.
I want to be able to create a wx.Panel that contains an axis for
plotting. Around it i want other panels containing various settings,
buttons etc. to control the plot. So far I can't even get the program
to actually show a plot in a panel.

I'm using matplotlib to generate (and save) plots of bandwidth data
from simulation logs. Since the simulations are of varying lengths, i
need a way to scale the axes so that every 100,000 points on the
X-axis are roughly equal to the height of the Y-axis. In other words,
if my X data varied from 0 to 575,000, my aspect ratio would be
roughly 6:1. If X goes from 200,000 to 400,000, then the aspect ratio
should be 2:1.

Hi everybody,
I've got a problem concerning matplotlib/pylab. I use it to represent
curves. I will use these pictures in a report.
However, it writes me a string 'date' on the bottom of my x-axis.
I use this to produce my date axis (x-axis):
mondays = WeekdayLocator(MONDAY) # every monday
months = MonthLocator(range(1,13), bymonthday=1)
# every month

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
