This is probably as close as MATLAB can approximate that plot:
The Code:
x = [0 10.3 344 0.0];
y = [0 1.8 10 11.8];
yi = linspace(min(y), max(y));
xi = interp1(y, x, yi, 'pchip');
figure(1)
plot(xi, yi)
grid
set(gca, 'YDir','reverse')
txtstr = sprintf('%.1f, %.1f\n', [x' y']');
txtlbl = regexp(txtstr, '\n', 'split');
text(x, y, txtlbl(1:end-1), 'FontSize',8)
The Plot:
