3. Draw a line in the figure. 4. Type the following code at the MATLAB command prompt to recover the GUI data in the form of a structure: data = guidata(figHandle); 5. Inside 'lineExample.m', the handle to the line has been stored as a field ...
I = imread('baby.jpg'); figure imshow(I) Draw a linear ROI over the image. Use the 'Position' name-value pair to specify the location and length of the linear ROI. Set the line to be striped red by specifying the 'StripeColor' name-value pair. Get h = drawline('Position',[500...
I want to draw lines on top of the image displayed in the GUI. For instance my GUI allows the user to input an angle theta. I want to draw a line on top of the figure which makes an angle theta with the x axis. How do I go about doing that? I know I can draw lines using ...

Unlike the plot function, the line function does not call newplot before plotting and does not respect the value of the NextPlot property for the figure or axes. It simply adds the line to the current axes without deleting other graphics objects or resetting axes properties. However, some axes...
