 Re: [Matplotlib-users] One more question regarding to boxplotting From: Gökhan SEVER - 2009-05-14 00:56:57 Attachments: Message as HTML ```Ok, With this figure, it is clearer to see what's wrong with two of my boxplots. I pull the original data and feed boxplot with it. The 1st boxplot is using only quartiles and the next is providing the actual data array. http://img140.imageshack.us/img140/4705/boxplots.png To me the second boxplot seems more convenient to put an academic paper. What do you think? These boxplots only show the variation in true air speed of a small leg of a research flight. Would there be a better representation of in addition to / as an alternative boxplotting?
