Shade the region to the left of the graph

Hi

I am trying to shade the region to the left of the graph. Does anyone know how to go about doing that? It would be a great help.

Thanks

My code is attached below

%Stall Speed 
rho = 0.002378; % at sea level
Clmax = 2.7;
Vs = 189.056;
WvS = 0.5*rho*Vs^2*Clmax;
x1 = WvS;
x2 = WvS;
y1 = 0;
y2 = 8;
plot([x1,x2],[y1,y2],'-g')
text(95,1.2,'Stall speed')
axis([0 120 -0.1 2])
xlabel('W/S, lb/ft^2')
ylabel('T/W, lb/lb')
grid on
hold on

Simplest way is to use patch(). Something like this

%Stall Speed 
rho = 0.002378; % at sea level
Clmax = 2.7;
Vs = 189.056;
WvS = 0.5*rho*Vs^2*Clmax;
x1 = WvS;
x2 = WvS;
y1 = 0;
y2 = 8;
plot([x1,x2],[y1,y2],'-g')
text(95,1.2,'Stall speed')
axis([0 120 -0.1 2])
xlabel('W/S, lb/ft^2')
ylabel('T/W, lb/lb')
grid on
hold on

patch([0 x1 x2 0], [0 0 8 8], 'r', 'FaceAlpha', 0.1);
