I'm trying to create a grid based heatmap like the one shown here

The code to generate it is here:

However, when I run the code (MacOS), I get something very different:

There is much more gradation and the hard edges are all gone. How can I get the hard edges like on matplotlib's website?

`im = ax.imshow(harvest, interpolation='nearest', cmap='viridis')`. The example image has `cmap='jet'`, which [isn't a good idea](https://www.youtube.com/watch?v=xAoljeRJ3lU). Maybe there is a very old version of matplotlib installed? – JohanC Mar 25 '20 at 00:38
Take a look at [this answer](https://stackoverflow.com/a/8376685/10659910), might be helpful – William Miller Mar 25 '20 at 01:14
I ran the example on mac too, I got the expected result. Can you share your matplotlib version? – ilke444 Mar 25 '20 at 04:42
@WilliamMiller’s answer helped. @ilke444, how can I tell what version I have? I just have what came with the OS. – easythrees Mar 25 '20 at 04:44
`import matplotlib` `print(matplotlib.__version__)` – William Miller Mar 25 '20 at 04:45
The version seems to be 1.3.1 – easythrees Mar 25 '20 at 04:48
