1) Is there a way to control the size of the map? Does this depend on the
shape files used??


Currently there is not an option to control the size of the graph using -tmap-. I believe -tmap_choropleth.ado- calculates the size of the graph by using the below code.



local RATIO = (`ymax' - `ymin') / (`xmax'-`xmin')

local YS = 4

local XS = 4 / `RATIO'



If you wanted to you can edit the file tmap_choropleth.ado and manually add the X and Y sizes you want. For example,



local RATIO = (`ymax' - `ymin') / (`xmax'-`xmin')

local YS = 4

local XS = 4 / `RATIO'

local YS = 5 /// Add ysize

local XS = 5 /// Add xsize




Is there a way to show deciles of "quantvar"?


The -clnumber(#)- options specifies the number of classes k in which quantvar can be divided. This option accepts only numbers between 2 and 9.

-tmap- is great!

A couple of questions:
1) Is there a way to control the size of the map? Does this depend on the
shape files used??
2) Is there a way to show deciles of "quantvar"?

Thanks,
