Zooming Feature Notes

1. It is planned to automate the zoom cap edit process in future releases of EAS with an automated code writing utility.

2. It is not necessary to add an indicator to the zoom cap for zooming to work. It is only necessary if one wishes a view's y-axis to scale automatically. The x-axis always scales regardless of whether the indicator has been entered in the zoom cap or not.

Editing the Zoom Cap
The zoom cap refers to the set of program lines within the dynzoom.oms function that controls which indicators or price charts are rescaled. To add an indicator to the zoom cap edit the /EAS/utility/function/dynzoom.oms file. Look for blocks of code similar to that shown in the links below. The editable section is labeled in the file:

# ****************************** BEGIN USER ZOOM CAP ******************************
# put your code here


# ****************************** END USER ZOOM CAP ********************************

There are many ways for the zoom cap to be modified, two examples are given in the links below:

Zoom Cap Editing Methods:

Zoom Cap Edit Method 1: The first way is to initialize the view so that a view's plot is erased and then completely redrawn.

Zoom Cap Edit Method 2: Rescale the view using data without initializing the view.
