Hi,
I am using drawpolyline function to draw polyline, it works well without any issues.
I have a question as below.
Is it possible to provide hint/suggestion to the user who is drawing polyline on their axes like the next polyline should be draw within the specified xy coordinates, if so could you please do help me out how to do it ?
or
the next polyline should be drawn on xy coordinates instead of empty data ?

I have gone through it and did not find it therefore i have raised this question.
I did not understand how to define it.
can you please provide a sample code like
Draw = drawpolyline() %% enables user to draw polyline
how shall i give hint to the user to draw new polyline/vertex based XY coordinates.
