My program works at the moment, but I'm trying to better understand why.
These three lines define x-axis tick labels for axs[0] subplot:
The second line is necessary to avoid "ConversionError: Failed to convert value(s) to axis units."
ax.set_xticks() arguments are list of tick locations, list of tick labels, and rotation amount.
Isolated from anything else (e.g. not part of a dataframe), what does it mean to have a DatetimeIndex? Is that just a type of object like a range object or generator object?
If I print(type()), then for lines 1 and 2, respectively, I get <class 'pandas.core.indexes.datetimes.DatetimeIndex'> and <class 'pandas.core.indexes.base.Index'>.
Why is the first object type not acceptable to line 3 (I'm guessing that's what causes the ConversionError) while the second is?
These three lines define x-axis tick labels for axs[0] subplot:
xtick_labels = pd.date_range(btstats['Date'].iloc[0],btstats['Date'].iloc[-1],20)
xtick_labels_converted = xtick_labels.strftime('%Y-%m-%d')
axs[0].set_xticks(list(np.linspace(1,len(btstats.index),num=len(xtick_labels_converted))),xtick_labels_converted, rotation=45)The first line gets date range from first and last value of 'Date' column.The second line is necessary to avoid "ConversionError: Failed to convert value(s) to axis units."
