![]() I generally discourage mixing the functional and object-oriented approaches, but in this case I think it's worth it. That's why, for now, I recommend using plt.xticks() for this rather than the object-oriented approach. That means they are a bit more complicated for our use case. However, it's a bit more work and there's more going on behind the scenes. Using set_xticks() and set_xticklabels() affords us greater flexibility, rather than just letting plt.xticks() use its default behaviour. set_xticks ( range ( len (polls ) ) )īut now we're back to the original state of duplication! It's necessary when using set_xticklabels() to also use set_xticks() to define what the x ticks are:Īxes. ![]() Hence just using set_xticklabels() will often not to exactly what you want. When we do set_xticklabels() though, we're giving names to the ticks that exist in order, which means ticks end up with labels, and ticks end up without labels. That means that if you have 6 polls, you end up with ticks rather than. Therefore we must give a name to the tick at each index.Īnd by default, matplotlib creates one tick too many at each end of our provided values. We have 6 bars in our chart, starting at position 0, and ending at position 5 (given by our range(len(polls))). set_xticklabels ( for poll in polls ], rotation = 30 ) return figureīut if we do this, we're no longer telling the axes how many ticks there are, and so it reverts back to generating its own ticks. bar ( range ( len (polls ) ), for poll in polls ] )Īxes. set_title ( "Polls to their vote counts" )Īxes. import matplotlib.pyplot as plt x 1, 2, 3, 4 y 1, 4, 9, 6 labels Frogs, Hogs, Bogs, Slogs plt.
