I think drawpolyline functionality for uiaxes has been recently added (r2020a). I am using r2019a and i got following.error:

Functionality not supported with UIAxes. For more information, see Graphics Support in App Designer.

Error in images.roi.internal.ROI/extractInputNameValue

Error in images.roi.internal.ROI/parseInputs

Error in images.roi.Polyline

Refer documentation of drawpolyline here.

https://www.mathworks.com/help/images/ref/drawpolyline.html

It was specified that input for drawpolyline can be 'axes' or 'uiaxes' object
