Plotting bar chart matplotlib.pyplot python

Question

I have these very close values to plot using bar chart:

[0.786418528, 0.836312033, 0.796715391, 0.834506989, 0.834181085, 0.792882691, 0.787157068]

But they appear to be very closed projected on y axis.

How to make them look more discriminated likes this one from excel?

Answer 1

If you know from before the rough range of your data, you can just set the ylim:

plt.ylim([y_min, y_max])

A smart way of doing this would be to automatically infer the boundaries of your data from the vector you have (assuming it's called y):

y_min = min(y)
y_max = max(y)
offset = (y_max-y_min)*0.3 # To give us some leeway
plt.ylim([y_min-offset, y_max+offset])
