I am drawing oceanic depth-temperature plots for values in the present day, and into the future e.g. 2016,2030 & 2090. On top of these I am overlaying additional oceanic variables for the same time slices.
What I have done thus far:
go multi_xaxis_plot1 ts[d=1],ts[d=2],ts[d=3] 2 !
go multi_xaxis_overlay ph[d=1],ph[d=2],ph[d=3] 1 "-" "7.5,8.2,0.1" "pH" " " 0.6 !
go multi_xaxis_overlay pco2[d=1],pco2[d=2],pco2[d=3] 2 "-" "300,900,50" "pCO2" " " 0.6 !
Which works very well, however the colours are different for each line and therefore it’s impossible to decipher the 9 lines.
What I would like to do, thereby making it easier to read, is to draw in (say) black, the ts[d=1] as a solid line, ts[d=2] as a dashed line, and ts[d=3] as a different dashed line. Then repeat this with pH and pCO2 in (say) red and green. In summary 3 colours, one for each variable, with the time slices marked by the same line style.
Does anyone know how this can be done? Or a way around this?
Thanks in advance,
