Hi,
I was wanting to use dual scales on my plot and was just running the example
code from
http://matplotlib.org/examples/api/fahrenheit_celsius_scales.html
I subsequently changed the function Tc to read
def Tc(Tf):
return Tf
Fully expecting the two scales to track each other perfectly

Hi,
I have an application that draws a line plot of a spectrum. When the

data point (which I have also collected). I am looking at artefacts in
the spectrum and trying to correlate them with things such as the gain

If I understand your question correctly you probably need to look at

Hi Alastair,
I don't have clue why yours doesn't work.
however I changed the following line in the update function
data[20]=data[20]+0.5
to
data = np.random.randn(100)
And it started updating the display, with new data each update.
maybe changing a single point is not seen as a big enough chan

Hi Christoph,
Sorry for my delay to get back to you.
The svn version seems to work fine with GTK support, at least my

Hi,
I just downloaded matplotlib-0.98.5.3.win32-py2.6.exe from sourceforge.
I have an existing Application that works fine with

GTK+ : 2.14.7
numpy: 1.2.1
matplotlib : 0.98.5.2
Now I am trying the same App on

This is absolutely fantastic, does everything I want, 1/2 hr after

I do have a question though.
