Canvas mouse tracking box location

[MBaz]

The documentation and the demos on gnuplot's webpage indicate that the mouse-tracking box in a canvas plot should appear on the bottom of the plot.

However, when I create such a plot myself, I see the box on the left of the plot. Furthermore, the grid button does not work, and I see a button with sort of a double "A" that is not there in the demos.

Here is a screenshot that shows what I see: https://i.imgur.com/7DHeg9A.png

To reproduce (I'm using gnuplot 5.4), run these commands:

set term canvas mousing
set output 'test.html'
plot sin(x)
set output

and then open 'test.html' in a web browser.

Does anyone know what is happening here, and how can I obtain plots as shown on the demos and described in the documentation?

Here is what gnuplot outputs with the commands given above: https://gist.github.com/mbaz/c6106679b7c01ce58ab422a5b5dbd025

I have found that there are several different classes in the mousebox CSS, and `mbleft` is the one used in the canvas html. I was hopeful that changing it manually to `mbunder` would help, but it didn't.

I also saw the example canvas demo plots for gnuplot 5.5 (unfortunately, the 5.4 canvas demos are 404). Besides much cleaner html, it uses the `mbunder` class, and disables the "text zoom" button.

Hm, the output html doesn't work at all on firefox/win7

The firefox web console complains with the following, anybody know
what's wrong there? The paths are correct. Can't be the
slash/backslash mixture, can it?

I was able to place the mousebox under the plot by copying the layout from gnuplot's demo page. This works: mouse zoom, mouse tracking, printing and clearing coordinates with the left and right mouse buttons, and the zoom reset/restore buttons. This doesn't work: grid on/off button, turning plots on/off.
