[FIXED] set y-axis in millions

Issue

I have a problem with this plot:

The y-axis is in unit but I need them to be in millions as such:

Do you know a method to achieve this? Thanks in advance.

Solution

You can use a custom FuncFormatter like this:

from matplotlib.ticker import FuncFormatter
import matplotlib.pyplot as plt
def millions(x, pos):
    'The two args are the value and tick position'
    return '%1.1fM' % (x * 1e-6)


formatter = FuncFormatter(millions)

fig, ax = plt.subplots()
ax.yaxis.set_major_formatter(formatter)

Or you can even replace millions with the following functions to support all magnitudes:

def human_format(num, pos):
    magnitude = 0
    while abs(num) >= 1000:
        magnitude += 1
        num /= 1000.0
    # add more suffixes if you need them
    return '%.2f%s' % (num, ['', 'K', 'M', 'G', 'T', 'P'][magnitude])
