laguill<p>Hi fedi 😊<br>I am struggling with <a href="https://fosstodon.org/tags/vegaaltair" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>vegaaltair</span></a>.</p><p>Do you have any resources of density faceted plots ?</p><p>I am trying to <a href="https://fosstodon.org/tags/plot" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>plot</span></a> densities of a selection of columns of a <a href="https://fosstodon.org/tags/dataframe" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>dataframe</span></a> with mean and median highlighted.</p><p><a href="https://fosstodon.org/tags/dataviz" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>dataviz</span></a> <a href="https://fosstodon.org/tags/DataScience" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>DataScience</span></a> <a href="https://fosstodon.org/tags/Python" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Python</span></a></p>
David<p><a href="https://aus.social/tags/Programming" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Programming</span></a> question:</p><p>How do you equip yourself with the right vocabulary so you can find the function you want?</p><p>Context:</p><p>Something I struggle with in <a href="https://aus.social/tags/coding" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>coding</span></a> is not having the vocabulary to look up functions that do what I want.</p><p>A good example of this (in <a href="https://aus.social/tags/python" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>python</span></a>): I wanted to re-arrange data in a <a href="https://aus.social/tags/pandas" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>pandas</span></a> <a href="https://aus.social/tags/DataFrame" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>DataFrame</span></a>. I knew what the input looked like, and I knew what I wanted the output to look like, but I didn’t have the vocabulary to describe the transformation.</p><p>This meant I couldn’t easily find an appropriate function, without reading the entire documentation.</p><p>So I wrote the transformation in a round-about way, that was relatively convoluted.</p><p>Later, I stumbled across the term reshaping, and through that term, found the <a href="https://aus.social/tags/melt" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>melt</span></a> function (part of the pandas package!), which exactly met my needs.</p>
