Program for box plot charts? - (Jul/23/2011 )
anyone knows a good (and/or free) program to make box plot diagrams?
Excel is not really able to create such charts
In this thread the mentioned excel alternatives can mostly make boxplots (I use Sigmaplot and it works well, but the software is not free).
For Excel several add-ins and templates exit to help excel (though not all are good). Just search them with google and try out.
At the moment I use R for boxplots.
From my experience, excel did a bad job in boxplot. I used to get a few online excel template to do such work and the data calculated were not even correct, after I compare with SPSS and Minitab14.
For online boxplot: try:
hope this helps
Thank you all for your help and suggestion.
A friend of mine has an licence of Origin 8.5.
This program is very very handy to make boxplots (but unfortunately very expensive).
