dear all,
stata 8.2,
my data set-up look something like this:
subject laser1 laser2
1 1 2
2 2 1
3 3 3
4 2 4
5 3 1
. . .
. . .
. . .
. . .
. . .
316 4 1
there were 316 subjects. laser1 has categories which take the values of 1 to 5 but returns from the subjects showed only categories 1 to 4 i.e. none of the subejct reported 5, likewise with laser2. i want to create a graph ala [G] page 134 of Stata 8 [G]raphic manual, where the y-axis would show the total count of the subjects for each category while x-axis would show categories 1 to 5, with the chart itself consisting of two bars of different colors for each laser1 and laser2.
i tried various gr bar commands but just couldn't produce the kind of graphs that i want. using catplot e.g.:
catplot bar laser1 laser2, asyvars
came close but somehow it is showing 3 bars in some categories when it should only be showing two bars i.e. one for each laser1 and laser2 respectively. the other thing is i also want to show on the graph is category 5 (i.e. value of 5) on the x-axis albeit it'll be empty i.e. 0, but where in using the above command, only 1 to 4 in the x-axis was displayed.
i would appreciate any advice/help either using the gr bar route or the catplot route or both to achieve what i wanted to show.
thank you,
bw
