Boxplot: allow whiskers to always cover entire range #1455
Description
Sometimes, one needs to have the whiskers of a boxplot cover the entire data range. This is typically achieved by setting whis to a large enough value. However, if the 25-75 percentiles are identical, then the value of whis has no influence, and no whiskers are drawn.

@phobson another old boxplot issue that you might want to look at.
phobson commentedon Nov 27, 2013
@tacaswell Thanks. Will do.

@stefanv it just occured to me that you can already accomplish this by setting the
whiskwarg to something sufficiently high -- 1e6 should be safe for most real-life datasets ;)stefanv commentedon Dec 3, 2013
@phobson Like the bug description states: the value of
whisis ignored under certain circumstances.phobson commentedon Dec 3, 2013
Well I certainly missed that part. Apologies.
But if Q1 == Q3, then Q2 (median) == Q1 == Q3 and I'm not sure how much boxplots are going to tell you.
That said, I can add some logic in #2643 that if Q1 == Q3, the whisker limits can fall back to 5th/95th percentiles or min/max.

I think as long as the whiskers do not disappear I'd be quite happy! Thanks for having a look at this @phobson

@phobson Did this get taken care of by #2643?
phobson commentedon Feb 27, 2014
Yes. With the
whiskwarg, you can now pass 'range' or a list ofpercentiles.
