-fulltab- could be fixed, but as it's broken, you should consider other ways. I'd look into a -reshape-, so that your variables become subsets. With data like this, not every category is represented. set obs 20 set seed 2803 forval j = 1/5 { gen y`j' = ceil(10 * runiform()) } So, we -reshape-. gen id = _n reshape long y, i(id) graph pie , over(y) by(_j) I'd also not use pie charts! Nick n.j.cox@durham.ac.uk Martin Weiss -ssc d fulltab- is quite old (1998), so to get it to work, you have to specify an appropriate -version-: ************* clear* input a b c 2 3 1 4 5 1 1 2 1 3 6 0 end compress list, noo version 7: fulltab a b if c==1, vals(1 2 3 4 5 6) m(mymat) ************* Weirdly enough, -fulltab- does not include a -version- statement in its code... Adam Collins I expect there is something really simple that I am missing here... but I am new to Stata and it is doing my head in that I can't display all categories of a categorical variable on a pie chart... I am really getting no where with this problem. I would really appreciate some help. I tried exploring ways of storing the "counts" from my categorical variable values in another variable, such as a matrix which would allow me to store a "zero count" as a "0" value. In searching for a solution, I came accross -fulltab- (from SSC), however it doesn't seem to work (it just displays the following "program error: code follows on the same line as open brace"). Anyway, I am not even sure this is the best approach. Surely there is something more straight forward? Adam Collins I have several categorical variables that each possess the same list of categories (value labels). To enable easy comparison of the pie charts, I would like every category to exist on every chart (so that each category retains the same colour/settings/legend position etc on each chart). The problem is that some of the variables contain zero occurrences of certain values (categories) and the standard 'over(varname)' option with -graph pie- excludes categories with no occurrences. I have tried the 'allcategories' option, but since it applies to the 'over()' variable, it does not help. Does anyone have any ideas? (by the way, since this is for a specific set of categorical variables, it is fine if the categories are 'hard coded', then applied to each variable) * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
