In JMP there are two methods that might work, depending upon your table setup. Likely a contour is what you want
Below is a picture, from JMP sample data Little Pond. Its x axis is spatial distance not time. You will have to customize the color scheme. A script to create the picture follows.
You can produce a contour with Main Menu Graphs > Contour Plot or Graph Builder. Contour plot has more customization.
From Contour choose Days and Depth for X and Dissolved Oxygen for Y Ask to fill areas. You can choose your levels for the Z variable (Dissolved Oxygen).
Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Little Pond.jmp" );
obj = dt << Contour Plot(
X( :X, :Y ),
Y( :Z ),
