I have a dataframe that looks like this:
A ... B
datetime ...
2020-01-01 00:00:00 10.622 ... 30
2020-01-01 01:00:00 16.397 ... 30
2020-01-01 02:00:00 24.190 ... 30
2020-01-01 03:00:00 33.579 ... 30
2020-01-01 04:00:00 44.643 ... 30
... ... ...
2020-01-07 20:00:00 18.090 ... 30
2020-01-07 21:00:00 18.027 ... 30
When I use df.plot, all columns are plotted with default colors and solid lines. I would like to plot columns A to x in the same color but with different markers and columns x+1 to B in another color with the same markers.
Is this somehow possible without manually declaring it for every column seperately?
Thanks!
You can create a custom cycler for this task:
from cycler import cycler
import numpy as np
import matplotlib.pyplot as plt
import pandas as pd
markernr = 3
colornr = 2
#test data generation
np.random.seed(123)
df = pd.DataFrame(np.random.random((10, 6)), columns=["A1", "A2", "A3", "B1", "B2", "B3"])
colors = ["tab:red", "tab:blue", "tab:orange", "brown", "lightblue", "yellow"]
markers = ["x", "o", "D", "+", "H"]
my_cycler = (cycler(color=colors[:colornr]) *
cycler(marker=markers[:markernr]))
fig, (ax1, ax2) = plt.subplots(1, 2, figsize=(10, 6))
df.plot(ax=ax1, title="Standard cycler")
ax2.set_prop_cycle(my_cycler)
df.plot(ax=ax2, title="Customized cycler")
plt.show()
