I just have a one question for mpg dataset sns.histogram(cars.horsepower, kde=true) is it equal to the plot we obtained from sns.kdeplot(cars.horsepower)

@KimberlyFessel 3 жыл бұрын

Thanks very much for subscribing! And yes, you should get the same KDE plot; however, the sns.histplot(cars.horsepower, kde=True) will also give you a histogram under the KDE plot. The histplot will also likely truncate/cut the edges of your KDE plot.

How would you plot multiple KDE on the sample plots? Specifically, if I have columns as different conditions and each row a measurement of that condition.

@KimberlyFessel 3 жыл бұрын

The newest version of the kdeplot (Seaborn 0.11.0) allows for the hue argument to split out data into different color groups based on a categorical variable. You can also just plot two kdeplots on the same figure: sns.kdeplot(X) immediately followed by sns.kdeplot(Y) in the same Jupyter cell or before doing plt.show(). That would just layer one plot on top of the other -- assuming you have similarly scaled values.

Thanks very much! Yes, I have started using some external data in a few of my recent videos. One thing you could definitely try is loading your data into a pandas dataframe and then doing a KDE plot for your column(s) of choice. Just keep in mind that if you have a lot of data you might need to sample it. I will also consider making a follow up video for this one! ☺

Could someone explain to a n00b how we are using "cars = sns.load_dataset('mpg').dropna()" ? *dropna* is a Pandas method but we have not imported Pandas, only seaborn, so how does it work to chain dropna onto seaborn.load_dataset() ? it shouldn't be available? My understanding is that dropna has to be available to load_dataset, but dropna is not in the seaborn API, only in pandas API.
