Time-space plot with meshgrid?

I am given a table with three columns

x              t         color
0               0         10
0.1             0          9
0.2             0         11
0.3             0         3
0               0.1         10
0.1             0.1          9
0.2             0.1         11
0.3             0.1         3

The table is given by a variable P. so that x=P(:,1), t=P(:,2), color=P(:,3).

I want to make a 2D plot in which the x axis is x, the y axis is t, and every point (x,t) is colored according to the values of P(:,3) (preferably in a grey scale).

I know that in order to make a plot, I need to use meshgrid for x and t. But how can I make the "color" in accordance with the values after using the meshgrid?

Hope I made myself clear

Thanks in advance !

I need to plot similar chart. Could you please guide me how should I do the meshing?

Is there any examples on how to create these charts ?

Try this:

figure(1)
scatter(P(:,1), P(:,2), [], P(:,3), 'Filled')
grid on
colormap(jet(10))
