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

Many thanks, that helper.
After some more problems with scipy, I got a working EXE.
PyQt4 is still in the library, though. Eating almost 15Mb... Now all I

Hi,
I have an application that draws a line plot of a spectrum. When the
spectrum is collected different gains and filters may be used for each
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
and
However if I am zoomed in on my graph looking at detail, then click the
radio button, the scatter plot forces the graph to resize to once again
show the overall intial view (zoomed out).
Try using:
axes.set_autoscale_on(False)
Thank you very much, this does exactly what I was
Hi,
Sorry haven't used ipython, so not sure if there is another/better
ipython way.
Attached is how I solved it in normal python.
I added a next line button to the graph, and set the ydata for the
line each time the button is pushed.
There is a couple of set_ylim lines commented out,

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

I don't have clue why yours doesn't work.
however I changed the following line in the update function

And it started updating the display, with new data each update.
maybe changing a single point is not seen as a big enough

Why don't you perform a histogram on the data that produced that
