no space allocated for labeling category axis with graph dot / graph hbar

[Liz Foster]

I am making dot graphs over various categorical variables, and for one of them (provider), Stata doesn't allocate any space for the labels of the different categories. Both provider (doesn't work) and province (does work) are labeled, numerical variables. Note that it looks fine with the vertical option. I same thing happens using graph hbar : no space allocated to label the different values of provider. (If you open the graph with the graph editor, you see that no space is allocated for grpaxis.)

. des provider province

              storage   display    value
variable name   type    format     label      variable label

province        byte    %10.0g     provs17    Province (2017 frame)

. graph dot paid [pw = _pweight], over(care) asyvar over(provider)

. graph dot paid [pw = _pweight], over(care) asyvar over(province)

. graph dot paid [pw = _pweight], over(care) asyvar over(provider) vertical

As I write (and as I read) the images are unreadable. Please note the advice to post images as .png. If you used any other file format, that is unlikely to work.

It's your first graph that is problematic. I get a better result by tweaking the aspect ratio:

set scheme s1color 
graph dot paid [pw = _pweight], over(care) asyvar over(provider)  aspect(1)

[Andrew Musau]

You can specify how much space you want allocated to the margin.

graph dot paid [pw = _pweight], over(care) asyvar over(provider, axis(outergap(20)))
