Hi,
I am developing a GUI in which a context menu is assigned to each line drawn by "plot" command. One thing that needs improvement is that there are many lines and right clicking on them needs precision. Therefore, I provided a zoom capability. The problem is when I zoom, it has no effect on the width of the line and it stays as thin as before no matter how many times you zoom in. I tried to change the width of the lines, but seems like the handle is not assigned to the width of the line. Do you have any suggestions that zooming can make it easier to right click on lines?
Thanks, Mehrdad

If the lines conceal eachother, increasing the linewidth (or the width susceptible for detecting a right-click) will not help. In opposite, it will increase the problem.
You could move the context menu to a kind of legend. See:
I'm using a tool, which determines the nearest line, when I click in an axes. Then this line is highlighted and the space key selects the next line. Finally the right-click opens the context menu of the axes, wich is adjusted dynamically, such that it looks like it is the context menu of the selected line.

You can use patch objects instead of line, which increases the visible and susceptible area. And as said before: You can catch the right click in the axes, determine the nearest line and set its ContextMenu to 'Visible' -> 'on' programmatically.

A suggestion on modifying the width of individual lines in a plot:
You can create a handle to the plot command and then access each line individually and modify its LineWidth property. Consider the following example:
x1 = 1:10;
y1 = x1;
y2 = x1.^2;
h = plot(x1,y1,x1,y2);
set(h(1),'LineWidth',5);
set(h(2),'LineWidth',10);

Thank you for the answer. I had already tried that and as I mentioned, the area that you can right click on a line for the context menu doesn't get bigger with increasing the line width.
