I am currently comparing trajectories from different meteorological datasets and some specific locations and I'm struggling a bit with the colouring.

I would like to have at each of my points the same colour per model.

First I simply run hysplit once per model - each time with my 3 points. However what ever options I used with the -k options in trajplot, I only got different colours per point, but not per model.

Then I did it the other way around: looping over my 3 points and running for each of it hysplit with the different meterological datasets.

This worked well as long as I had 3 models with the command

- Code: Select all
`${MDL}/exec/trajplot -i+filelist -otrajplot_${number}.ps -g0:1200 -h71:-45`

where filelist contains my different trajectories in the order

point1model1

point1model2

point1model3

point2model1

point2model2

point2model3

point3model1

point3model2

point3model3

But now I have four models, and I can't convince trajplot to use more than 3 colours and thus I do not have anymore one colour per model at each point, but at the first point one trajectory of color 1, one of color 2 and two of color 3 - and similar at the other points.

I tried -k12:123412341234 and -k4:1234 and k12:111222333444, but nothing is giving me the effect that I'm looking for. Basicly whatever I put leads to haveing one and the same colour everywhere!

Is there anyway to prescribe the colors? Did I misunderstood the use of the -k option?

Also, I was wondering, is there a simple way to set up a legend, i.e. saying that color red corresponds to model 1, color blue to model 2 etc?

Thanks a lot for your help,
