读取数据

load_path=‘ADJ.mat‘
load_data = sio.loadmat(load_path)
a = load_data[‘D‘]

将a包装为df框架

x_axis = [

"1a", "2a", "3a", "4a", "5a", "6a", "7a",

"1p", "2p", "3p", "4p", "5p", "6p", "7p"]

x_axis = [
"1a", "2a", "3a", "4a", "5a", "6a", "7a",
"1p", "2p", "3p", "4p", "5p", "6p", "7p"]
y_axis=x_axis
df = pd.DataFrame(a,columns=x_axis)
df.index=x_axis
print(df)
pt =df

import matplotlib.pyplot as plt

f, ax = plt.subplots(figsize=(6, 4))

cmap = sns.cubehelix_palette(start=1, rot=3, gamma=0.8, as_cmap=True)

sns.heatmap(pt, cmap="BuPu", linewidths=0.05)
ax.set_title(‘Adajencent matrix‘)
ax.set_xlabel(‘Nodes‘)
ax.set_ylabel(‘Nodes‘)
plt.show()`

results

HeatMap 这个坑值得有姓名
