Detailed Description

Implements an overlay box which shows the mouse coordinates in plot units.

When mouse is moved over the mpWindow with an active mpInfoCoords layer, the mouse coordinates (in mpWindow units, not pixels) are continuously reported inside the layer box.

inline

Set X axis label view mode.

Parameters

mode	mpLabel_AUTO for normal labels, mpLabel_TIME for time axis in hours, minutes, seconds.
time_conv	set time format Local or UTC

UpdateInfo()

void mpInfoCoords::UpdateInfo ( mpWindow &  w, wxEvent &  event  )

virtual

Update the content of the info box.

Used to update coordinates.

Parameters

w	parent mpWindow from which to obtain information
event	The event which called the update.

Reimplemented from mpInfoLayer.
