Plot pandas dataframe containing NaNs

Question

I have GPS data of ice speed from three different GPS receivers. The data are in a pandas dataframe with an index of julian day (incremental from the start of 2009).

Answer 1

Given that you want to draw a straight line between the points where you do have data, you can get Pandas to fill in the gaps via interpolation, and then plot:

.interpolate(method='linear').plot()
