Hi,
I am working on scripts using numpy, scipy and matplotlib to analyze some image
data. I would like to be able to select the particular image I want to analyze,
so I need a file selection dialog or similar. I know this can be done with any
gui toolkit, but I was wondering if there isn't an

Suppose I have the following data set
-
Time Temperature (F)

I want to make a plot with both y axes labeled. The one on the left (y1)
will be in Fahrenheit,

Tkinter makes this pretty easy. E.g.,

fname = fd.askopenfilename(initialdir='c:/temp')

That's all, as long as you don't
Hello there,
This is my first post, so first of all, thanks to the
creators/contributors of matplotlib. It's a very nice software.
I've been developping an application using PyQT and matplotlib for a
while now, and instead of coding the GUI, I'd like to make use of QT
designer.

Hi,
I want to implement a cursor on a diagram using native Qt routines. For
this, I would need to transform data (axis) coordinates to display
coordinates.
The manual of matplotlib, API axes just jays that there are some
public attributes 'transData' and 'transAxis', but without an
explanation.
Hi again,
when I scroll or zoom with the mouse wheel, the scaling of the x and y
axes are changed within the event. I would need now the new value of
these to update the status bar. How can I get them without waiting for a
new mouse event?
Cheers
Ole

Exactly. I want to plot the original data once, but the two y axes show
different scales (units). Is twinx() good for that? How?
Thanks.

I wouldn't call it good, but you can make it work. Basically, you'd plot
your data once in F,
I hope the code below gives you some idea.
def Tc(Tf): return (5./9.)*(Tf-32)
ax1 = subplot(111) # y-axis in F
ax2 = twinx() # y-axis in C
def update_ax2(ax1):
y1, y2 = ax1.get_ylim()
ax2.set_ylim(Tc(y1), Tc(y2))
# automatically update ylim of ax2 when ylim of ax1 changes.
Hi All,
i want to change my subplots sometimes, but how to do this ?
I am adding subplots with this command:

Deleting axes with(as i read in this mailing list):
[self.figure.delaxes(a) for a in self.figure.get_axes()]

This works nicely. Thank you JJ.

I am trying to set the x and y axis range on a log-log plot. The ranges I
give are automatically adjusted to the nearest power of 10, but I would like
to have the minimum and maximum axis values not be powers of 10. Is there a
way to set the axis range so that it is not automatically rescaled?
