The barogram displays a red cross-hair to show the altitude at the currently selected time. Initially this will be equal to the airfield elevation (usually close to zero).
If the width of the browser window is reduced sufficiently, the horizontal line of the cross-hair slides downwards and appears underneath the x axis:
The narrower the window becomes, the further the cross-hair moves.
As soon as the barogram is replotted (when the time slider is moved or the units are changed), the cursor goes back to the correct position.
Further to the above, in all browsers, the crosshair remains static relative to the page as the graph is resized, which means that it no longer points to the correct place on the graph.
