从数据标签中散布 Plot 二进制数据颜色编码点

Question

I'd like to use matplotlib.pyplot.scatter to create a scatter plot similar to the picture below from data in a dataframe with a header that is formatted similar to the table here where all the points for a given sample are colored based on the label in the first column of the data and a point is only plotted for each gene with a value of 1 - no point for the genes with a 0 value:

label	gene a	gene b	gene c	gene d
1	0	1	0	0
0	1	1	0	1
0	0	0	1	0
1	0	0	0	0
1	0	1	0	0

Note: my sample data does not match my sample scatter plot output.

Answer 1

After melting your dataframe to a long format you can draw a matrix with seaborn'ssns.relplot

import pandas as pd
import seaborn as sns
sns.set_style("ticks")

df = pd.read_html('https://stackoverflow.com/q/70856944/14277722')[0]
df['sample'] = df.index
df = df.melt(['label','sample'])

g = sns.relplot(
    data=df,
    x="variable", y="sample", hue="label", size="value",
    hue_norm=(-1, 1), palette='tab10',
    height=6, sizes=(10, 300), size_norm=(0, 1)
)
g.set(xlabel="Genes", ylabel="Samples");
