Just a quick post today, to tell you about a couple of simple zsh functions that I find handy as a Python programmer. First, pyimp – a very simple function that tries to import a module in Python and displays the output. If there is no output then the import succeeded, otherwise you’ll see the […]
Another quick matplotlib tip today: specifically, how easily specify colours from the standard matplotlib colour cycle. A while back, when matplotlib overhauled their themes and colour schemes, they changed the default cycle of colours used for lines in matplotlib. Previously the first line was pure blue (color='b' in matplotlib syntax), then red, then green etc. […]
As you may have noticed, I hadn’t blogged here for quite a while, but have recently started blogging regularly again. This is mostly due to sorting out various WordPress issues I was having, and installing some new plugins to make writing blog posts fun again. Ever since I installed the WordPress update that added the […]
I keep gathering links of interesting Python things I’ve seen around the internet: new packages, good tutorials, and so on – and so I thought I’d start a series where I share them every so often. Not all of these are new new – some have been around for a while but are new to […]
Following on from my last post on plotting choropleth maps with the leaflet-choropleth library, I’m now going to talk about a small addition I’ve made to the library. Leaflet-choropleth has built-in functionality to automatically categorise your data: you tell it how many categories you’d like and it splits it up. However, once I’d set up […]
Some work I’ve been doing recently has involved putting together a webmap using the Leaflet library. I’ve been very impressed with how Leaflet works, and the range of plugins available for it. leaflet-choropleth is an extension for Leaflet that allows easy generation of choropleth maps in Leaflet. The docs for this module are pretty good, […]
When producing some graphs for a client recently, I wanted to hide some labels from a legend in matplotlib. I started investigating complex arguments to the plt.legend function, but it turned out that there was a really simple way to do it… If you start your label for a plot item with an underscore (_) […]
A user of Py6S recently contacted me to ask if it was possible to get an output of Rayleigh reflectance from Py6S. Unfortunately this email wasn’t sent to the Py6s Google Group, so I thought I’d write a blog post explaining how to do this, and showing a few outputs (reminder: please post Py6S questions […]
You can probably tell from the sudden influx of matplotlib posts that I’ve been doing a lot of work plotting graphs recently… I have produced a number of boxplots to compare different sets of data. Some of these graphs are for a non-technical audience, and my client agreed that a boxplot was the best way […]
Just a quick post here to let you know about a matplotlib feature I’ve only just found out about. I expect most of my readers know how to produce a simple plot with a title using matplotlib: plt.plot([1, 2, 3]) plt.title('Title here') which gives this output: I spent a while today playing around with special […]
