`ggplot`

ggplot is the base layer or object that you use to define the components of your chart (x and y axis, shapes, colors, etc.). You can combine it with layers (or geoms) to make complex graphics with minimal effort. ggplot has 2 parameters:

(1) What data is going to be used for your plot (the data frame being used)
(2) How that data is going to be displayed (the aesthetics)

You can add layers to ggplot to build up your plot. For the example below we'll start with a ggplot that has the x aesthetic defined as the price column from the diamonds dataset. We'll then add a geom_histogram to it and then finally add scale_x_continuous to customize the x-axis.

p = ggplot(aes(x='price'), data=diamonds)



In [3]:

    
p + geom_histogram()









    












    Out[3]:





<ggplot: (284507049)>



In [4]:

    
p + geom_histogram() + scale_x_continuous("Price ($)", breaks=[0, 10000, 20000])









    












    Out[4]:





<ggplot: (284507049)>
