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

Here is another way:

nan_columns = []
nan_values = []

for column in dataset.columns:
    nan_columns.append(column)
    nan_values.append(dataset[column].isnull().sum())

fig, ax = plt.subplots(figsize=(30,10))
plt.bar(nan_columns, nan_values)
