I have 2 axes on a GUI. How to show the cursor on both plots at the same X axis value?

Hello,

I have a GUI with two diferent axes with ploted data.

I can activate the cursor but only on one of them. I want to show the cursor on both axes and at the same X value.

Of course if I change the position of the cursor on one of axes, I want the cursor on the other plot to change to the same X position.

Many thanks!

Thanks for your quick answer Sean.

I accept your answer but it only solves half of the problem. Anyway now I also can get the cursor position and plot the data tip over it.

But I have another problem: how to delete this cursor tip?

I know than plotting again it will be erased, but there is other way to do it without plotting? Because I also use the arrows to move the cursor data tip, but if I hold the key it hangs.

Thanks!

This hide all the data cursors:

 a = findall(gcf, 'Type', 'hggroup');
 set(a, 'Visible', 'off');

Now only left how to handle the axes to use the makedatatip without plotting.

This is how I'm doing it now, but when the plotting function finishes, I can't use again the handles.hPlot without plotting:

 hPlot = plot(data);
 makedatatip(hPlot, [1 3]);

Any idea?

Use the datatip's delete method:

hDatatip = makedatatip(hobj,pos);

To remove it:

delete(hDatatip)
