Python scattered in different colors depending on value
I have a dataframe that I want to make a scatter chart.
the dataframe looks like this:
year length Animation
0 1971 121 1
1 1939 71 1
2 1941 7 0
3 1996 70 1
4 1975 71 0
I want the dots on my patch to have a different color depending on the value in the animation line.
So animation = 1 = yellow
animation = 0 = black
or something similar
I've tried the following:
dfScat = df[['year','length', 'Animation']]
dfScat = dfScat.loc[dfScat.length < 200]
axScat = dfScat.plot(kind='scatter', x=0, y=1, alpha=1/15, c=2)
The result is a slider that makes it difficult to distinguish.

You can also assign discrete colors to points by passing an array to c = Like this:
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
d = {"year" : (1971, 1939, 1941, 1996, 1975),
"length" : ( 121, 71, 7, 70, 71),
"Animation" : ( 1, 1, 0, 1, 0)}
df = pd.DataFrame(d)
print(df)
colors = np.where(df["Animation"]==1,'y','k')
df.plot.scatter(x="year",y="length",c=colors)
plt.show()
This gives:
Animation length year
0 1 121 1971
1 1 71 1939
2 0 7 1941
3 1 70 1996
4 0 71 1975
