[ncl-talk] removing/changing options in pressure/precipitation plots

[Juan Carlos Anduckia]

Hello:

I'd like to remove/change the following features in the attached pressure and precipitation plots:
In the former, how to remove the legend "Contours: 1009 to 1015 by 0"?
In the latter, how to change in the color bar ".1" and ".4" and put instead  "0.1" and "0.4"?
Thank you.
