Draw subplots boxplot using python

Question

I want to draw two parallel box plot in together. For that I used sub plots function in python, below code I used for the that process, but I couldn't get good out put from the code, because its already draw addition two empty graphs, how I remove these empty graphs from the output? Please give ideas for that?

f, axes = plt.subplots(2,2,figsize = (14,10))
sns.boxplot(x='Heating QC',y='SalePrice',hue='Central Air',  data=df ,ax=axes[0,0])
sns.boxplot(x='Heating',y='SalePrice',hue='Central Air',  data=df ,ax=axes[0,1])

out put

After changes got below outputs

IndexError                                Traceback (most recent call last)
<ipython-input-543-7dfa6ebf0390> in <module>
      1 f, axes = plt.subplots(1,2,figsize = (14,10))
----> 2 sns.boxplot(x='Heating QC',y='SalePrice',hue='Central Air',  data=df ,ax=axes[0,0])
      3 sns.boxplot(x='Heating',y='SalePrice',hue='Central Air',  data=df ,ax=axes[0,1])

IndexError: too many indices for array

plt.subplots(2,2) creates a 2x2 grid of subplots, that's why you've got 4 plots showing.You need to change it to to a 1,2 or 2,1 as you see fit. matplotlib.org/api/_as_gen/matplotlib.pyplot.subplots.html — David Buck

@DavidBuck yes I changed plt.subplots(1,2) then there no any outputs, only give error massage and empty two graph. I add that out put and error massage in question section. — randunu galhena

Your ax now need to change to just axes[0] and axes[1] as you only have a one dimensional array of subplots. That's covered here: stackoverflow.com/questions/54170394/… — David Buck

@DavidBuck now code is working properly thanks your support. — randunu galhena

Just create two plots, in which case axes will be a list of 2 elements and use those plot.

Refer the documentation.

f, axes = plt.subplots(2, figsize = (14,10))
sns.boxplot(x='Heating QC',y='SalePrice',hue='Central Air',  data=df, ax=axes[0])
sns.boxplot(x='Heating',y='SalePrice',hue='Central Air',  data=df, ax=axes[1])
