R Question

I need to create a scatter matrix in Python. I tried using scatter_matrix for this but I would like to leave only the scatter plots above the diagonal line.

I`m in the really beginning (did not got far) and I have troubles when columns have names (not the default numbers).

Here is my code:

`import itertools`

import numpy as np

import matplotlib.pyplot as plt

import pandas as pd

data=pd.DataFrame(np.random.randint(0,100,size=(10, 5)), columns=list('ABCDE')) #THE PROBLEM IS HERE - I WILL HAVE COLUMNS WITH NAMES

d = data.shape[1]

fig, axes = plt.subplots(nrows=d, ncols=d, sharex=True, sharey=True)

for i in range(d):

for j in range(d):

ax = axes[i,j]

if i == j:

ax.text(0.5, 0.5, "Diagonal", transform=ax.transAxes,

horizontalalignment='center', verticalalignment='center',

fontsize=16)

else:

ax.scatter(data[j], data[i], s=10)
