Hi All,
I want to shade(filled) several regions in a 2D plot by different colors. The attachment contains the plot I am expecting to plot. I could not find a better tutorial to plot this figure yet. Could you please give some help on this. Thank you in advance.
The boundaries of the given region is given by following functions.
P1 = range from 0 to 5
temp = range from 600 to 1600
Tttg1 = 760.-60.*(P1-1.)**2.
Tttg2 = 1000.-150.*((P1-1.2)/1.2)**2.
Pttg1 = -0.5*((temp-870.)/220.)
Pttg2 = 1.5+0.7*((temp-700.)/200.)
Pttg3 = 1.
Tttg3 = 1000. # pr3
Tttg4 = 1100.+50.*((P1-3.5)/3.5)**2. # pr4
Pttg4 = 2.35 +0.15*((temp-1000.)/100.) # Tr4/1000
Pttg5 =5.
lpttg_con = (temp>Tttg1) & (temp<Tttg2) & (P1>Pttg1) & (P1<Pttg2) & (P1<Pttg3)# & matcon_WB
mpttg_con = (temp>Tttg1) & (temp<Tttg2) & (P1>Pttg1) & (P1<Pttg2) & (P1>=Pttg3)# & matcon_WB
hpttg_con = (temp>Tttg3) & (temp<Tttg4) & (P1>Pttg4) & (P1<Pttg5)
Thanks
Prasanna
