How do you do freestyle drawing in MATLAB?

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?

You need to provide the data, if you want the exact shape of the curve.

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

Thank you @Chunru. How do you make the curve not too steep? It is not an exponential curve

[Chunru]

The formula:

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