No of labels on axes of small multiples (scatter)

[R Allan Reese]

I'm drawing a plot of multiple time series, each one starting at a different date and different durations. There are 15 series and the data is sorted by groupid and date. The stripped down command has the form:

scatter y date , c(L) by(groupid, col(5) rescale) xlab(#4)

I'm quite happy with the result except that some of the plots have 4 dates labelled, some 5, some 6 but one has only 2 (min and max). This does not seem to relate to the length of the series: a Jan21-Jul23 has 6 labels while Jul20-Apr22 has the 2.

Changing to xlab(#5) causes the odd graph to have 8 labels, which is rather excessive!

Any suggestions how I can tweak this to make the number more uniform? (Other than draw 15 graphs and combine them manually!)

If you're creating the scatter plots individually, you could try using

xlabel(minmax)

or

 xscale(range(1000 5000))

I also recommend the help function in Stata using Scatter or axis_choice_options.
