matplotlib中cm表示colormap，即色彩的内置函数。RdYlBu表示颜色。
代码如下：
from pylab import *
import matplotlib.pyplot as plot
import pandas as pd
filePath = (“C:\dataTest.csv”)
dataFile = pd.read_csv(filePath,header=None,prefix=“ZW”)
print(dataFile.iloc[0:2,0:2])
minRings = -1
maxRings = 99
nrows = 10
for i in range(nrows):
dataRow = dataFile.iloc[i,1:10]
labelColor = (dataFile.iloc[i,10]- minRings) / (maxRings - minRings)
dataRow.plot(color=plot.cm.RdYlBu(labelColor),alpha=1)
print(dataRow)
plot.xlabel(“Attribute”)
plot.ylabel(“Score”)
show()
结果如图：
