<p dir="auto">Using the same code and seaborn 0.8.1 and matplotlib 1.5.3 (ipykernel.pylab.backend_inline), I cannot reproduce empty circle markers (same goes for seaborn = 0.7.1, matplotlib = 2.0.2 ). Instead, I get:<br>
<a target="_blank" rel="noopener noreferrer nofollow" href="https://user-images.githubusercontent.com/783826/31318472-3f83c622-ac4b-11e7-9980-44d9af9236cc.png"><img src="https://user-images.githubusercontent.com/783826/31318472-3f83c622-ac4b-11e7-9980-44d9af9236cc.png" alt="" style="max-width: 100%;"></a></p>
<p dir="auto">Is it still possible to set the marker facecolor using the current seaborn release?</p>
<p dir="auto">Seaborn kdeplot does not return handles or labels from legend, and it does not allow any customization whatsoever of legend.<br>
Try for yourself with the iris flower dataset using the kdeplot function with the hue set by species.</p>
<p dir="auto">Here is my simple code:</p>
<div class="snippet-clipboard-content notranslate position-relative overflow-auto" data-snippet-clipboard-copy-content="sns.kdeplot(data=afrisar_df_ha, x=&quot;Ndens, hue=&quot;Site&quot;, ax=ax[0])
ax[0].legend(loc=&quot;upper left&quot;, title=None)"><pre class="notranslate"><code class="notranslate">sns.kdeplot(data=afrisar_df_ha, x="Ndens, hue="Site", ax=ax[0])
ax[0].legend(loc="upper left", title=None)
</code></pre></div>
<p dir="auto">Error message returned is:<br>
"No handles with labels found to put in legend."</p>
