[ncl-talk] color_bar_show only higher and lowest value and make colorbar continuous(not to show one box per color).

[Adam Phillips]

Hi Sebastián,
Note that the example you pointed to shows all 252 colors of the BlueRed
colormap, while your example only has 21 contours and thus would only show
22 colors.

You can turn the label bar boxes off by setting lbBoxLinesOn = False*. *See
example #18 here:
http://www.ncl.ucar.edu/Applications/labelbar.shtml#ex18

By turning that resource off, and by using say 100+ colors (and thus
100+contours), one can get the label bar to look continuous.

Hope that helps. If not, please respond to the ncl-talk email list.
Adam
