Pcolor plot question. gradational color change.

I have Time X ( 81 x 1 ) and Y ( 81 x 20 )

Y is a some value at the time X, with coefficient from 1 ~ 20.

when I plot (X,Y) , the result is like below figure.

Can I make a pcolor plot using a different coefficient as a Z value (1~20) ?

I want draw figure with poligonized gradational color change, not with the multiple lines

Answer 1

[KSSV]

x = 1:20 ;
y = TIME ; % 81x1 array
Z = Y ;   % 81x20 array
pcolor(x,y,Z) ;  % if required transpose Z
