Re: [ferret_users] Managing tick labels on the x-axis

["Fiedler, Russell (O&A, Hobart)" <Russell.Fiedler@xxxxxxxx>]

Hi Billy,

There's no need to employ the old "use climatological_axes;can data climatological_axes" work around. Those axes are automatically loaded nowadays. They have been for quite a while (says Russ with his copy of the V3.1 user manual sitting within an arms length).

Cheers,

Russ

Since it looks like you have more than 1 year of data, you can get ferret to do the monthly averaging for you, using the original data directly:

set dat climatological_axes; can dat climatological_axes 

let mydata_cl = mydata[gt=month_irreg@mod]

shade mydata_cl 

This is especially useful if your data time axis is irregular, or extends over partial years. In those cases, the average of mydata_cl:

mydata_cl[l=@ave]

is a better estimate of the mean than the simple mean:

mydata[l=@ave]

! this avoids weighting parts of the year with more observation. 

@mod makes the axis extend indefinitely, thus allowing plotting the climatology over the original data:

plot mydata  ! more than 1 year, possibly irregular

plot/over mydata_cl 

Or finding anomalies:

let mydata_cl2 = mydata_cl[gt=mydata]   ! put the climatology onto the original time axis

let mydata_anom = mydata - mydata_cl2

Hi,

You'll need to put your variable onto a climatological time axis.

Rather than

shade anom

try

let myanom=anom[gt=MONTH_REG@asn]

!or any of the axes that show up with sho axis/all

shade myanom

Hi there,

I'm generating maps for zonal anomalies [of wetland methane emissions] over 12 months (see attached image) and I'd like to replace numerical labels for the x-axis (ie. 1, 3, ..., 11) by Jan, Mar, ..., Nov.

Can someone please suggest how to achieve that?

FYI, I'm using FERRET v7.1 (optimized).

Thanks in advance,

CM
