<br>
I am trying to create a label bar from scratch using the color table<br>
"BlAqGrYeOrReVi200". I create 25 equally-spaced levels spanning<br>
between 100 and 340 with an interval of 10. Using span_color_indexes,<br>
I create 26 colors<br>
<br>
Variable: colors<br>
<br>

26 values<br>

(24) 193<br>
(25) 201<br>
<br>
I do not understand why the color bar only shows 25 colors and not 26.<br>
Also, I thought that the location of the label "100" would be located<br>
on the right edge of the firtst box on the left, as usually seen in<br>
most examples on the Label Bar web page. Can somebody clarify what I<br>
am doing wrong. The pdf is<br>
/glade/p/work/laura/DATA/CERESdata/CERESorbits.2014-01-10_to_2014-01-14<br>
(plot_CERES_SSF_XTRK-MODIS_Edition4A_original_data_markers.pdf) and<br>
the ncl script is<br>
CERES_SSF_XTRK-MODIS_Edition4A_Subset_plot_original_data_with_marker.ncl.<br>
<br>
Thanks,<br>
