Hi, so I have this plot, it could be like this:

 a=[[1:1440]'];
 Totalset=[a a*0 (sin(a./20)+2)*100  a*0 cos(a./20)*9+20]
 AX=plotyy(Totalset(:,1),Totalset(:,5),Totalset(:,1),Totalset(:,3))
        set(AX(2),'ydir','rev')
        hold on
 set(get(AX(1),'Ylabel'),'String','Kernetemperatur(C)')
        set(get(AX(2),'Ylabel'),'String','Dybde(m)')
        y_venstre_min=10
        y_venstre_max=30
        y_hojre_min=50
        y_hojre_max=300
        set(AX(1),'YLim',[y_venstre_min,y_venstre_max])
        set(AX(2),'YLim',[y_hojre_min,y_hojre_max])

And, now I have this matrix:

MTRX=[1 0 1 0 1 0 1 0;23 75 149 400 600 1100 1300 1400]'

I want my background to change to dark grey when MTRX(:,1)=1, and back to white when it goes back to 0 etc. So that my background would be white from 0 to 23, dark grey from 23 to 75, white from 75 to 149, dark grey from 149 to 400, and so on.

Is this possible, and do anyone have an example to help me get started I spent some time looking for this, but could only find how to change the colour of the entire background?

Best regards, Nicki Eriksen
