How to plot a line graph of an array from a dataframe?

I have a dataframe, test, that contains winter temperatures since 1951 for a city. I want to plot the temperatures contained in the column called p95_annual but when I try to do that using plt.plot(test.p95_annual.values) I get the following:

Here’s what test, wintermean, and test.wintermean.values looks like:

How can I plot this temperature data?

>Solution :

You have one single row in your DataFrame which has a string. You need to parse the individual values from this string before plotting it:

data = list(map(int, test.at[124,"p95_annual"][1:-1].split()))

>>> plt.plot(data)
