Scale Text instead of Scale Bar?

ionarawilson1 — Wed, 31 Oct 2012 16:51:14 GMT

Hi,

Is it possible to have in a web app a dynamic scale text (like 1:24,000) instead of a scale bar? If so, where can I find an example or code snippet? Thanks

Here is the answer

<mx:Label text="Current map scale:" fontWeight="bold"/>
<mx:Label text="1:{myMap.scale.toFixed(0)}"/>

Not sure how I can have the thousands separator on the scale so I will post another thread!

Ionara,

You need to use a number formatter, add a declaration

<fx:Declarations>  <mx:NumberFormatter id="numFormatter" precision="0" useThousandsSeparator="true"/> </fx:Declarations>

Then you can use the formatter on your number

<mx:Label text="1:{numFormatter.format(myMap.scale.toFixed(0))}"/>

Regards

Anthony

Thank you Anthony!
I created a formatter but instead of creating the label directly I created a function for the extentChange event of the map:

private function updateScale():void
   {
    scaleText.text = myNumberFormatter.format(myMap.scale).toString();
   }

The scaleText is a label I created. I believe your version is better because it is much simpler!!! Thanks again!
