How to draw a polyline?

NilsWaap

Hello,

I would like to draw a polyline into a figure.

 

I tried to use the function 'polyline' but unfortunately there is no help availabe to this function.

 

I tried this:

polyline('position',[5 5;4 6;4 7;5 8;6 8;7 7; 7 6]);

 

But its not working. A figure is created without axes and polyline. No error messages occours.

 

Regards

Nils,

 

You are right, the Help is missing for this function and it will come in the next release (v2019.3).

 

The syntax for it would be:

     data = [5 5;4 6;4 7;5 8;6 8;7 7; 7 6]';
     figure(1);
     h = polyline(1, 'polydata', data);

Where the first argument is figure handle and the third one is the data set. In your case, the figure will be very small using these inputs:

 

But if you slightly change your data set to data = [5 5;104 106;104 7;5 8;106 8;7 7; 7 106]', for instance, we'd get:
