When Qt Wireshark's I/O Graph Time of Day checkbox is changed, the X Axis will
be immediately updated but any displayed graph(s) will be hidden and the X axis
label units will display either an unexpected (but consistent) time and date
value (checkbox enabled) or the Seconds will be displayed unexpectedly in
scientific notation (checkbox disabled).  If and when the mouse cursor is moved
into the graph frame section of the dialog the graph will be updated and
reappear and the X Axis label units will display with the expected values.

This issue has been seen on both OS X and Windows.

The Qt Wireshark I/O Graph dialog has a Time of Day checkbox that toggles how
the units for the X AXIS should be displayed: from Seconds (since start of
capture) to Time and Date.   The default is Seconds (the checkbox is disabled). 

How to replicate:

1 - Start Wireshark.

2 - Load the attached small capture file.

3 - Open the I/O dialog (Menu: Statistics / I/O Graph

With the default "All Packets" and "TCP errors" graph entries enabled several
traffic spikes of 13 packet/sec will be seen. 

4 - Click on the "Time of Day" checkbox to enable.

The Graph will clear and the X Axis units will now display a time of 19:00:00
and date of 31.12.69 for the date in the left most position.

5 - Move mouse cursor into the graph border.

The moment the mouse cursor is moved into the graph border an event will be
triggered that makes the graphs reappear and the X axis label will be updated
to display the expected time and date values.

Workaround: Move mouse cursor into the graph frame area to trigger updates
after Time of Day checkbox is changed.
