graph by()

[filippo dare]

Hi everyone, sorry for the stupid question but I am not able to find a solution by myself. I want to plot an histogram by another variable. The problem is that the resulting graphs are a lot and when I export them only some of them have the yaxis. I tried by reducing the size of the graph but nothing changes.

histrogram price, by(mpg)

In this for example, only the latter five graphs have the y-axis. Is there any way to add the yaxis to the others? thank you.

hist price, by(mpg, iyaxes)

[filippo dare]

Actually it does not work too

[Øyvind Snilsberg]

what do you mean does not work? is this closer to what you want,

hist price, by(mpg, iyaxes) ylabel(,format(%9.4g) angle(0))

?

How many histograms are we talking about? More about 25? You could fall back on graph combine but then the fraction of space that isn't showing data will go up yet more.

It's not so much a case of quite what syntax you might use as a case of is this graph really going to help anybody and would a different way to show the data work better?
