Description
The language C has the ability to print integer with added commas as the thousands separator, like printf("%'d", 12345) which can got the answer 12,345. This feature is required by some journals, and I always have to modify my figures by hand. So I am hoping the parameter D_FORMAT in gmtset has the power just as the C dose. (fig1)
Another possible useful feature is the annotations could been aligned vertically like fig2.
Thanks for your work.
Associated revisions
Make it possible to use a format like %'g to create separators for thousands.
This can be used for plotting axes on plots and in psscale.
This fixes issue #622.
Merge from trunk; fixed issue #622

In fact, I've always wanted to have an option to have D_FORMAT use the C-type format specification more generally. Now it can only used for floating point numbers. It should be a rather simple to scan the D_FORMAT statement and first cast (round) to integers when an integer format (%d or %i, etc) is used.
I will assign this to myself to be incorporated in 5.2.x.
As far as the right alignment: as far as I know annotations on the left-hand side of the plot are right-aligned already.

Not sure, put I think he might refer to the MAP_ANNOT_ORTHO effect, already implemented.
I agree the integer stuff should be fairly simple since this is for Cartesian annotations only and those are done in the GMT_xy_axis which sets the format using GMT_get_format. This could be modified to pass back a flag so that one can convert to int before printing.

The thousands separator can in fact easily be accomplished by setting D_FORMAT to %'g.
However, this will require some change in the code, because normally C does not recognise any of the language settings. To make this work, all we need to do is to add the following code:
#include <locale.h> setlocal (LC_ALL, "");somewhere during initialisation. Once that's done, GMT will follow the
LC_* settings. This will then also allow users to use a comma as the decimal point.
In principle, we can regard it as a bug that GMT does not follow the LC_* settings and hence it should be fixed in GMT4, GMT5.1 and GMT5.2.

I see that in GMT4 we have
#ifdef CYGWIN_LOCALE_TROUBLE
setlocale (LC_CTYPE, "C.ASCII");
#endifBut nothing like that in GMT5.
Would the CYGWIN issue also be helped with a simple
setlocale (LC_ALL, "");?

What I still remember is that #ifdef resulted after an update in Cygwin that cost me almost a week of debugging to find out the trouble. But since I don't remember anymore what the problem was and I don't use Cygwin anymore I don't know if
setlocale (LC_ALL, "");
would solve it as well

This solution will be to change the localisation setting LC_NUMERIC to en_US just before plotting a string with the format FORMAT_FLOAT_MAP that includes %', and then back to C right after that. The same can be done when printing strings of the format FORMAT_FLOAT_OUT in case that includes %'.

Additional note: Example 39 now uses this format in the psscale at the bottom as an example.
