I am trying to use pandas in python to plot the following higher-dimensional data: https://i.sstatic.net/34nbR.jpg
Here is my code:
import pandas
from pandas.tools.plotting import parallel_coordinates
data = pandas.read_csv('ParaCoords.csv')
parallel_coordinates(data,'Name')
The code fails to plot the data, and the Traceback error ends with:
Keyerror: 'Name'
What is the second argument in parallel_coordinates supposed to say/do? How can I successfully plot the data?
The second argument is supposed to be the column name that defines class
. Think ['dog', 'dog', 'cat', 'bird', 'cat', 'dog']
.
In the example online they use 'Name'
as the second argument because that is a column defining names of iris's
