Re: Replace Frequency With Percent in Histogram

Hi Dan,

The histogram code only allows you to put these special labels on the
right.

If you want to put them on the left, you will need to make a personal
copy of $NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl and edit it.

Where you see the lines:

       set_attr(res2,"tmYUseLeft", False)
       set_attr(res2,"tmYROn",True)
       set_attr(res2,"tmYRLabelsOn",True)
       set_attr(res2,"tmYRMode","Explicit")
       set_attr(res2,"tmYRValues",bins_at_pnice)
       set_attr(res2,"tmYRMinorValues",bins_at_pmnice)
       if(percentsign)
         set_attr(res2,"tmYRLabels",pnice+"%")
       else
         set_attr(res2,"tmYRLabels",pnice)
       end if

You will want to change YR to YL.

I haven't actually tested this, so let me know if it doesn't work.

You will also need to do Dennis' suggestion below of setting
tiYAxisString to "Percent" or "%".
