Seaborn kdeplot not plotting some data?
<p>I'm trying to get the <a href="https://stanford.edu/~mwaskom/software/seaborn/generated/seaborn.kdeplot.html" rel="nofollow">Seaborn kdeplot</a> example to work on my dataset. For some reason, one of my datasets isn't plotting at all, but the other seems to be plotting fine. To get a minimal working example, I have sampled only 10 rows from my very large data sets.</p>

<p>My input data looks like this:</p>

<pre><code>#Dataframe dfA
    index   x       y     category
0   595700  5   1.000000    14.0
1   293559  4   1.000000    14.0
2   562295  3   0.000000    14.0
3   219426  4   1.000000    14.0
4   592731  2   1.000000    14.0
5   178573  3   1.000000    14.0
6   553156  4   0.500000    14.0
7   385031  1   1.000000    14.0
8   391681  3   0.999998    14.0
9   492771  2   1.000000    14.0

# Dataframe dfB
    index   x      y      category
0   56345   3   1.000000    6.0
1   383741  4   1.000000    6.0
2   103044  2   1.000000    6.0
3   297357  5   1.000000    6.0
4   257508  3   1.000000    6.0
5   223600  2   0.999938    6.0
6   44530   2   1.000000    6.0
7   82925   3   1.000000    6.0
8   169592  3   0.500000    6.0
9   229482  4   0.285714    6.0
</code></pre>

<p>My code snippet looks like this:</p>

<pre><code>import seaborn as sns
import matplotlib.pyplot as plt

sns.set(style="darkgrid")

# Set up the figure
f, ax = plt.subplots(figsize=(8, 8))

# Draw the two density plots
ax = sns.kdeplot(dfA.x, dfA.y,
             cmap="Reds", shade=True, shade_lowest=False)
ax = sns.kdeplot(dfB.x, dfB.y,
             cmap="Blues", shade=True, shade_lowest=False)
</code></pre>

<p>Why isn't the data from dataframe <code>dfA</code> actually plotting?</p>
