Hello Gentlepeople,

I am plotting an integer array using: matplotlib.pyplot.plot().

For my purposes it is imperative that the x-axis be explicitly defined.

I have tried to achieve this by using: matplotlib.pyplot.axis(v).

Where v is a list of integer values corresponding to the desired axes limits [xmin, xmax, ymin, ymax].

However, the x-axis that is displayed does not obey my explicit xmax declaration; the value is rounded up.

Here is the relevant portion of my code:

fig = pyplot.figure(figsize=(16,8))

ax1 = fig.add_axes([0.05, 0.15, 0.9, 0.8])

v = [0, len(myintvector), 0, max(myintvector, key=int)]

ax1.axis(v)

ax1.plot(myintvector, 'r--')

The reason that I need the x-axis to match the length of my integer vector is because I am also drawing a colorbar immediately below the plot, the values of which describe the same integer vector. Therefore I need the colorbar coordinates to match the x-axis coordinates of my plot.

I hope that I have described my issue coherently. Please be kind (N00b alert).

Any help is greatly appreciated!

Sincerely,
