hi !
lets say i have an array of x,y 100 points and at each
point i have a correspoinding magnitude(of electric field) i want to
generate a contour plot of these intensity and if posible show contourn lines
how can i do these please any thing to start…
an example will be very helpfull

Dear John,
First of all, thanks for your response. When I try this

fig.canvas.manager.window.move(100,400)python tells me that window has no attribute move. It’s strange because I

Well, the example I posted was for a gtk window, not a tk window.
You will need to look at the API for the tk window to make the correct
call. We do not provide an abstract API across the GUI windows we
utilize internally. We give you access to the widget, and if you
want to make GUI specific calls on it, good luck, but this is not
encouraged or supported.

Well, the example I posted was for a gtk window, not a tk window.
And, for what it’s worth, wx spells it “Move()”, with a capital “M”.

I think this is what you are looking for:
from pylab import figure, show
fig = figure()
ax = fig.add_subplot(111)
ax.axesFrame.set_data((0,0,1), (1,0,0))
ax.axesPatch.set_edgecolor(‘white’)
ax.xaxis.set_ticks_position(‘bottom’)
ax.yaxis.set_ticks_position(‘left’)
ax.plot(range(10))
show()

Hi all,
I’m superimposing histograms of two data sets on the same axes, using
different colours and alpha transparency in the GtkAGG backend to show
the overlapping regions. If I plot a legend as below, the colours in
both legend entries are the same. Am I doing something wrong?
import matplotlib
matplotlib.use(‘GTKAgg’)
import pylab
pylab.hist(data1, normed=True, alpha=0.8)
pylab.hist(data2, normed=True, alpha=0.5, fc=‘yellow’)
pylab.legend([“data 1”, “data 2”])
pylab.show()
If I try this instead:
pylab.hist(data1, normed=True, alpha=0.8,
label=“data 1”)
pylab.hist(data2, normed=True, alpha=0.5, fc=“yellow”, label=“data 2”)
pylab.legend()
pylab.show()
the legend entries are now coloured correctly, but there is one label
entry for each bin, which is not particularly useful.
I’m using the latest SVN version of matplotlib (r3874).
I’d appreciate any comments and/or quick workarounds!

pylab.legend([“data 1”, “data 2”])
Here’s a workaround that probably explains why this is happening:
_, _, h1 = pylab.hist(data1, normed=True, alpha=0.8)
_, _, h2 = pylab.hist(data2, normed=True, alpha=0.5, fc=‘yellow’)
pylab.legend([h1[0], h2[0]], [“data 1”, “data 2”])
By default, the legend function assigns a legend entry to every patch in
the figure. Perhaps this could be seen as a bug in (hist or) legend, but
I don’t know how to fix it without introducing difficulties in other
cases.
