I
often use Ferret to plot data over small regions where the distance scale is
constant. I invariably want to add a nice looking distance scale, and do
so during post-processing of a GIF image. Is there a more direct
way? Has someone written a script that will do this on a Ferret
plot?
When I
plot lon/lat axes for these small areas the axis tick labels are in decimal
degrees. It would be nice to have an option for deg, min, sec labels where
the degree and or minute value appears only as many times as required (e.g., if
the range were from 124.15 to 124.25 then the degree label would appear only
once). At present I (again) do this during post-processing of a GIF
image.
When I
input west longitudes from a file in the format "xx.xxW" and plot the
data, the X-axis is inverted. For example, if the range is 135W to 133W
then the axis is plotted from 133 to 135. My solution is to input the
angles as negative values; however, this results in negative tick labels.
Am I doing something wrong or is this a bug?
On the
subject of aspect ratios in windows. It seems to me that if the X and Y
scales are equal, then there should be a way of having Ferret generate the
correct aspect ratio automatically after specifying either the X or Y
dimension. At present I am required to determine (min,max) ranges for both
X and Y axes, do a little bit of arithmetic, then specify the ASPECT=Y/X
option. This strikes me as something that arises so frequently that a new
option is warranted, thus letting Ferret do the math
automatically.
I
sometimes want to have more than one color bar appear on a plot. Is this
possible? When I overlay one shading on top of another I would expect both
color keys to appear, however this does not happen—only the original key
appears. Is there a way of having more than one color key? Also, can
one control the labeling (e.g., size, frequency, side of scale) and position
(e.g., left or right side of plot) of the key?
