How would I plot and connect two points properly?

I have a total of 4 numeric input boxes. The first two label x1 and y2 and the second two label x2 and y2. I am able to plot both coordinates on my graph, but I cant seem to be able to connect them with a line. Also when i plot them they do not plot to scale. Meaning I have to scroll through my graph in order to find the two coordinates. For example if i plot my x1 and x2 as (3,6) and my x2 and y2 as (4,7) i can only see my x1 and y1 coordinate and i would have to scroll to find my x2 and y2 because my x and y values would go by decimal increments(3.1,3.2,3.3,3.4....).
This is my code:
function PlotButtonPushed(app, event)
x=app.X1EditField.Value;
y=app.Y1EditField.Value;
a=app.X2EditField.Value;
b=app.Y2EditField.Value;
hold(app.UIAxes,"on");
plot(app.UIAxes, x, y,'mo--');
plot(app.UIAxes, a, b, 'md');
end
end

Ran in:
Instead of those two plot calls, do it this way.
x=1;
y=3;
a=2;
b=1;
plot([x, a], [y, b], 'm-d', 'LineWidth', 2, 'MarkerSize', 15);
grid on;
