Create a bigger graphic with Python and Matplotlib

Question

I'm a newbie and I would like to change the size of the bar chart I created with Matplotlib and Python, so I can show it in a presentation. I have very much values and the outcoming graphic is far too small. The columns 'State' and 'Hospital 30-Day Readmission Rates from Pneumonia' contain >50 values.

This is my current code:

smallgroup.plot('State', 'Hospital 30-Day Readmission Rates from Pneumonia', kind='bar')
plt.title("Hospital 30-Day Readmission Rates from Pneumonia")
plt.xlabel("States")
plt.ylabel("Readmission Rates")
plt.savefig('readmission_rate_pneumonia.png');

Do you want to change the size of the entire figure? Try setting figsize if so. stackoverflow.com/questions/332289/… — Petergavinkin

It doesn't work. The bar chart is still 432x288 px and the bars are now too big to deifne. With the current px size I have to use a width < 0.5. But this doesn't change the size of the whole graphic. I need a bigger picture.

you should adjust your figure size to your bar size...here information about figure : matplotlib.org/api/figure_api.html
