I want to create this graph. I did it with EXCEL but it is not good quality. I want to use MATLAB to create it. How do I do it in MATLAB?

Reading the description, I don't think there is any data. That looks like it's generated with primitives like rectangles and a bezier curve.

This gives you a schetch. You can fill up the rest using "text" and "plot" commands.
x = 5:30;
y = .2*(x-12).^2 -30;
plot(x, y, 'y-', 'LineWidth', 3); % j curve
hold on
plot([0; 35], [0; 0], 'b-', 'LineWidth', 2); % x-axis
plot([0; 0], [-40; 40], 'b-', 'LineWidth', 2); % y-axis
plot([0; x(end); x(end)], [y(end); y(end); 0], 'b--'); % C
text(-2, -20, 'Deficit', 'Rotation', 90)
xlim([0 35]);
box off
axis off

The formula:
x = 5:30;
y = .2*(x-12).^2 -30;
