| Attribute Name | Description |
|---|---|

It is used to specify whether the gauge will be rendered as editable. Setting this attribute to 1 will render an editable gauge, setting it to 0 (default) will render a normal gauge. If a gauge has multiple dials and all have them have to be made editable, the |
Method used to Create Editable Gauges in the Previous Versions
For users who have been using the previous versions, you this a brief recap of how to create an editable gauge.
Once the user has changed the value of the gauge, the gauge automatically calls the FC_ChartUpdated(DOMId) JavaScript function.
You will need to define this method in your HTML page and then write the JavaScript code to retrieve the data using getData(index) or getDataForId(id) method as shown below:
