Hi,
Can anyone help me with this error?
I suspect it is something to do with the data type, but don't know how to
resolve.
I'm trying to plot a 2 user system dates against each other and am getting the
error below.
print(type(DialogUsers.TRDAT))
<class 'pandas.core.series.Series'>
plt.scatter(DialogUsers.TRDAT, DialogUsers.ERDAT)
plt.show()
