Hi all,
I am trying to draw a heatmap using matshow, which I then save as a PDF.
If I then zoom in in the PDF, I notice that different rows have different
sizes, and different columns have different sizes. It seems that some
rows/columns have twice the height/width as other rows/columns.
By default (when interpolation=nearest) matplotlib is performing
nearest neighbor interpolation on the image to the request PDF dpi
before storing it in the file. This results in rows and columns of
unequal size because the ratio from the original image to the
destination resolution is likely

Hi,
is it possible to perform a surface plot a NxM matrix with date-axes?
Similar to plot_date for 1D-Plots. The dates are available as an N-sized (or
M-sized) array of float values.
At the moment, I am using imshow or matshow for the color plots, but the
only way I found to manipulate the axes

Hi Matthias,
Thanks for the help. The problem is, however, that the 'extent' parameter
only manipulates the range of the (integer) values on the axis. Before
setting the *axis_date property, I need to set the axes data to arrays of
(non-equidistant) floats.
Best Regards,
Micha

Thanks again Eric for the updated matshow().
I apologise for repeating:
Since it has been decided (has it?) that matshow will retain the feature
that a new figure is created (with aspect ratio matching the matrix), then
if one adds a colorbar (a typical thing to do), the matrix height is

Frankly, I don't care how it's done: I wrote matshow long ago, back
when axis('scaled') didn't exist in the first place. If the same
result can be achieved by other means that are cleaner, I'm sure John
will accept a patch.
One of the matshow anomalies is that it
Why does pylab.matshow() create a new figure by default when no other
standard pylab function I know of does that? It seems very
inconsistent for no particular gain, since as always
figure();matshow(m) will achieve that result if that is what is
desired.
