Subject: [amibroker] Synchronize zoom levels with static variables and
ZoomToRange


I would appreciate some help from more experienced programmers.

Assume several chart windows open and Symbol- as well as Interval-
linked. Challenge is to link the View Ranges, or Zoom levels: when 
zooming in/out or scrolling back/forth in any chart window all others 
would follow suit right away. (Personally I am used to zoom with 
Ctrl+"+" and Ctrl+"-" and scroll with PageDown and PageUp keys.)

Marcin at support help me on the way by providing this code:

_SECTION_BEGIN("ZOOM");

AB = CreateObject("Broker.Application");
AW = AB.ActiveWindow;

startDate = ParamDate("startDate", "2006-01-01", 1);
endDate = ParamDate("endDate", "2006-06-01", 1);
trigger = ParamTrigger("trigger", "ZOOM IN");
if( trigger ) AW.ZoomToRange( startDate , endDate);

_SECTION_END();

which, when added to to any window, enables triggering the zoom level 
from the parameters dialogue.

The additional step necessary would be to use static variables to 
pass the zoom dates from one window to another (i.e. set the static 
variable from one window, then in others read it and adjust the zoom 
level).

This is way beyond my programming expertise, and hope someone can 
help me with what explicit code to add to the various chart windows.

Thanks very much in advance!
