Re: [ferret_users] Fill and

Dear William,

Thanks for your answer. I definitely agree with you that Ferret is doing a wonderful job for contours, and plotting in general (especially time).

Concerning the contour, I did try CONSET at one point, but I did not play with SHAKEY because I only plot contours.

PPL CONSET did not solve my problem:

use coads_climatology.cdf
contour/x=50w:20e/y=30s:30n/lev=(20,23,1)/set SST[l=@ave]

ppl CONSET 0.08 1 1 0.04 0.04 0.0
ppl contour

Vijith indicated me a nice solution based on the ndigit inputs in /LEVELS=(lo, hi, delta, ndigits)

"ndigits (applies to CONTOUR command only) is the number of decimal places to use when labeling the level on individual contour lines as: -1 for integer format or -3 to omit numerical labels"

It works perfectly.

For the FILL/SHADE commands, I discovered it when I plotted some symmetric color scale for wind stress anomalies, which were not symmetric because of the missing last level... To obtain the right plot, I just added an extra level in the /LEVELS command, such as:

shade/x=50w:20e/y=30s:30n/levels=(0.014,0.030,0.001) SST[l=@ave]/1000

plots a color scale starting at 0.014 and ending at 0.029.

I do not understand why some specifications work and some do not. I will pay extra attention to my color scale, just in case the top-level disappears.

Many thanks,

Serena

With respect to occasional missing end values in the colorbar, I think this may be the result of rounding somewhere in the calculation (???). You can often work around this by tweaking the upper or lower bound by a tiny amount. E.g.,

If the original command fails:

shade/x=50w:20e/y=30s:30n/levels=(0.014,0.029,0.001) SST[l=@ave]/1000
Try:
shade/x=50w:20e/y=30s:30n/levels=(0.013999,0.029,0.001) SST[l=@ave]/1000

or:
shade/x=50w:20e/y=30s:30n/levels=(0.014,0.029001,0.001) SST[l=@ave]/1000

I don't know why these sometimes succeed when the apparently correct specification fails!
