<br>
Please consider the figure produced by "im = imshow(scipy.misc.face())". The message in the Toolbar reflects the position of the cursor and displays for example:<br>
<br>
"x=843.9 y=384.7 [91, 102, 88]"<br>
<br>
I changed the method "im.axes.format_coord()" in order to show specific information in the Toolbar message, and this works fine.<br>
<br>
However, the value of the cursor data, i.e. the string " [91, 102, 88]" in the example above, is still printed after my home-made coordinate information.<br>
<br>
PROBLEM: I don't want this information to be displayed.<br>
<br>
NOT A SOLUTION: I overrode the method "im.format_cursor_data()" so that it returns either "" or 'None'. However, in both cases, the brackets are still displayed, showing either " []" or " [None]", which I find unsatisfactory.<br>
<br>
It seems that the brackets are hardcoded in "backend_bases.NavigationToolb<wbr>ar2.mouse_move()".<br>
<br>
Is there a clean way to get rid of the cursor data and the brackets?<br>
<br>
If not, I suggest the patch below. Does it make sense? The effect is simply that if "im.format_cursor_data()" returns 'None', no cursor data will be appended to the coordinate information.<br>
<br>
Best regards,<br>
<br>
