Name: rate, Length: 108, dtype: object

Here is my basic code;

df.rate.astype(int).plot(figsize=(10, 10))
plt.suptitle('Rate Graphic')
plt.show()

The plot is like following;

Normally sensitivity much bigger than the plot itself, how can i increase the sensitivity on y axis?

For ex it shows 99.8 but i want to show it with more than 1 number after dot. Because my dataset is like ; 99.7131646900 etc.

How can i do that? Thanks,

You can use StrMethodFormatter:

from matplotlib.ticker import StrMethodFormatter

df.rate.astype(int).plot(figsize=(10, 10))

plt.gca().yaxis.set_major_formatter(StrMethodFormatter('{x:,.2f}')) # 2 decimal places
plt.show()
