matlab plot, interrupted line when y is zero

Hi,

I have a data that has some zero values but I would like to avoid to plot these values but I want a continues line between the previous and one after the data point. When I searched the web there are method to omit the zero values but the lines are broken. Instead I want to avoid the y=0 values but the code should plot a continues line before and after the y=0 values, Please see the plot. I would like to pass the data points of 5 and 7 and just connect the line between data point 4 and 6 and 6 and 7. Any idea? Thank you

figure(4)

x1=ModData(1:end,1);

x2=ExpData(1:end,1);

Mod=PD_Mod(:,7);

Exp=PD_Ex(:,4);

plot(x1,Mod,'gs-', x2,Exp,'r*-')

Try this, using your own ‘x’ and ‘y’ vectors:

x = 0:10;                                   % Create Data
y = randi([0 5], 1, 11);                    % Create Data

xnew = x;
ynew = y;

xnew(y == 0) = [];
ynew(y == 0) = [];

figure
plot(x, y)
hold on
plot(xnew, ynew)
hold off
grid

Experiment to get the result you want.
