Off topic:right way to working with dataframe and matplotlib

Question

[heuristic]

Hi !

I have a question about how I can work with pandas and matplotlib to make scatterplots.

I have a file space delimited like that:

    Flower1 Flower2 Flower3
Garden1 54  17  7   2
Garden2 28  49  13  4
Garden3 84  59  17  1
Garden4 17  3   29  0

In row 1 I have different flowers and in Column 1 I have different gardens, and I have values from Flower-Garden correspondence.

I try to make a scatterplot, using for example, the row 1 as x axis, and the column 1 as y axis, with the following script:

import matplotlib.pyplot as plt
import pandas as pd

df = pd.read_csv("flowers.txt",delim_whitespace=True)
ax = df.plot.scatter(x=df[1:0],y=df[0:1])

But an error occur: ValueError: Must pass DataFrame with boolean values only

Can anyone explain me how I can put those datas in the correct form?

thanks !
