Titles for groups within a legend

[Joe Ward]

Dear Statalist

I have produced a stacked bar chart of 15 mortality causes (displaying each as a percentage of all cause mortality). These causes can be divided in to 3 main groups. I would like to to produce a legend for this graph with titles for each of the three mortality cause groups. Is this possible?

The legend might look something like this:

Cause Group 1
Cause a -(blue)
Cause b - (green)
Cause c - (yellow)

Cause Group 2
Cause d - (brown)
Cause e - (purple)

Cause Group 3
Cause f - (yellow)
Cause g -(pink)

Any suggestions how I could do this?

Many Thanks
Joe

See under

help legend options

how you can add extra text to a legend.

It's hard to believe that a stacked bar chart with 15 categories works well, especially when your legend will consume perhaps 1/3 or 1/4 of the space. Are there other variables too?

Hi Nick

Thanks for your reply. I agree its too many categories on one graph, but wanted to see if I could group all the causes on one chart, but perhaps not!

thanks again for you reply

Joe
