resizing + negative values

[renderit]

Hi, great work here! I was looking into the prophet example with my own data. Had a few questions I can't solve.

• Is there a way to change the size of the plot? I tried plt.rcParams['figure.figsize']=(20,10) but that isn't working for some reason
• Why is values in weekly and yearly forecast plots negative? (ex if you do m.plot_components(forecast);)
• In the yearly plot, from forecast dataframe, it shows from January 1 to January 1, but i can't understand which year it is?

My last columns of forecast df looks like:

forecast.head() starts from 2013-01-02...
