How to implement in a colorbar legend a decreasing scale

[Beginner1]

Hi,

I wonder how to implement a decreasing scale in a colorbar legend. The scale
should start at 25 and finish at 1. I tried with the command caxis([25,1]),
but the console gave me an error:
"error: caxis: LIMITS must be a numeric 2-element vector where LIM1 < LIM2"

So I guess the problem is with the fact that the scale is decreasing. If I
reverse the limits, caxis([1,25]), this works properly but I need to show
the variation in a decreasing tendency...

Any advice?


Thanks
