I have written my program for this challenge, however when I run it with the test module I am getting the following errors: EEEE ====================================================================== ERROR: test_bar_plot_number_of_bars (test_module.CatPlotTestCase) --------------------------------…

sns.catplot doesn’t return figure object, but FacetGrid object. Similarly sns.heatmap returns ax, not figure.

For the catplot function I am using the variable name fig because that is what is provided in the challenge template. It is just a variable name though, for example: fig = sns.catplot(x=“variable”, y=“total”, hue=“value”, col=“cardio”, data=grouped_df_cat, kind=“bar”) print (fig) returns <se…

It’s not as expected, tests expect figure object. Notice that you aren’t actually printing type of the self.ax, but just str representation of it. Using type(self.ax) instead likely would reveal numpy.ndarray.

You are correct, using type(self.ax) returned numpy.ndarray You say that the tests expect figure object, however the medical_data_visualizer.py template states that we should use the sns.catplot() and sns.heatmap() methods which, as you have previously stated, return FacetGrid and ax. This doesn’t…

In case of sns.catplot it’s just needed to use certain attribute of the FacetGrid, which contains the figure.

@sanity is correct. If you dig through the seaborn and matplotlib documentation, you’ll find that many (not all) seaborn methods return a FacetGrid, which contains a matplotlib Figure object, which in turn holds an Axes object. Looking at my code, I access the Figure in the FacetGrid returned by s…

I finally got the catplot() aspect working, just had to add .fig to the end of the sns.catplot() method call (which I admit I saw on another thread). I’ll look into the heatmap error now. Many thanks for your help with this topic it is much appreciated.

I managed to get the heatmap errors cleared using .figure at the end of the heatmap call. I have a different problem now. When the test_heat_map_values test is executed I am getting an error because the expected list has an extra three empty values at the end. ===================================…

@craig.lunney now that your code is squared away… deleting the empty strings in test_module.py will fix the issue my apologies for withdrawing the solution previously…
