Line Plot with Markers possible?

Hello,
I am plotting a dataset and, as you can see, when a hysteresis is closed he gets back to a certain point. That's what the code does and that is good so far but in the plot he jumps to that certain point and plots a line:
When the plotting is done with a marker the line won't appear.
I'd prefer to use a line plot. Is there a trick to avoid "jumping-lines" in a line plot or maybe use lines in a marker-plot?
my code:
hp=plot(0,0, 'o'); %initial plot
for i=1: ...
%calculating stress - strain relation, then
set(hp,'xdata',Eps(1:i),'ydata',Sig(1:i))
pause(0.1)
drawnow
end
Regards

To break a line, introduce a NaN value after the last valid point prior to the next; it'll be in the [X|Y]Data arrays, but plot and friends will ignore it so won't show.
Alternatively, when get to the end of one loop, instead of continuing with that line, start a new one and the next data point; to do this you'll need an array of line handles that can increment as needed.

To avoid "line jumping" you need to insert a NaN or Inf into the data at the place you want the break to appear.
You can get a line plot by changing
hp=plot(0,0, 'o'); %initial plot
to something like
hp=plot(0,0, '-'); %initial plot

To plot both a line and a marker at the same time, put both along with the colro in the single quotes. For example to plot a red line with asterisks:
plot(x, y, 'r*-', 'LineWidth', 2, 'MarkerSize', 15);
grid on;
Adapt as needed.
