try this

plt.xticks(np.arange(100, 200, step=1))

for your case i.e. Time on x-axis you can see this post https://stackoverflow.com/a/16428019/5202279

plt.figure(figsize=(100, 5), dpi=100)
plt.plot(df['Time'], df['sale'], label='sales')
plt.xlabel('Time ')
plt.xticks(np.arrange(100),df.Time[100:200],rotation=45)
plt.ylabel('sales')
plt.title('sales')
plt.legend()
plt.show()
  • np.ararange(100) indicate 100 X axis value want to show
  • and df.Time[100:200] get the last 100 string value from data set df.Time
  • rotate the labe 45 degree

thanks for your support
