What you have now is
plot(app.UIAxes,app.t,app.y,'bs');
which plots blue squares at the points given by (app.t,app.y).
If you change it to
plot(app.UIAxes,app.t,app.y,'-bs');
then that would plot blue squares at the points (app.t,app.y) with a solid blue line connecting them.
Or perhaps you want:
plot(app.UIAxes,app.t,app.y,'-b');
% or simply
plot(app.UIAxes,app.t,app.y,'b');
which would plot a solid blue line with no squares (or markers of any kind).
See:
for other line style/marker/color options.

function StartbuttonButtonPushed(app, event)
app.y = [];
app.t = [];
i = 1;
start = tic();
cla(app.UIAxes,'reset');
app.UIAxes.YLim = [0 20];
while true
app.y(i) = 100 * app.arduino_pinwrite.readDistance();
app.t(i) = toc(start);
plot(app.UIAxes,app.t,app.y,'-bs');
drawnow();
if app.Stop == true
break;
end
i = i+1;
end
end
