<mx:Application name="HSlider_labelOffset_test"
        xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">

    <mx:ApplicationControlBar dock="true">
        <mx:Form styleName="plain">
            <mx:FormItem label="labelOffset:">
                <mx:HSlider id="slider"
                        minimum="-20"
                        maximum="60"
                        value="-10"
                        snapInterval="1"
                        tickInterval="5"
                        liveDragging="true" />
            </mx:FormItem>
        </mx:Form>
    </mx:ApplicationControlBar>

    <mx:HSlider id="sl"
            labels="[0,5,10]"
            labelOffset="{slider.value}"
            tickInterval="1" />

</mx:Application>

View source is enabled in the following example.

You can also set the labelOffset style in an external .CSS file or <mx:Style/> block, as seen in the following example:

View MXML

<?xml version="1.0" encoding="utf-8"?>
<!-- http://blog.flexexamples.com/2008/12/26/setting-the-label-offset-on-an-hslider-control-in-flex/ -->
<mx:Application name="HSlider_labelOffset_test"
        xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">

    <mx:Style>
        HSlider {
            labelOffset: 20;
        }
    </mx:Style>

    <mx:HSlider id="sl"
            labels="[0,5,10]"
            tickInterval="1" />

</mx:Application>

Or, you can set the labelOffset style using ActionScript, as seen in the following example:

<mx:Application name="HSlider_labelOffset_test"
        xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">

    <mx:Script>
        <![CDATA[
            import mx.events.SliderEvent;

            private function slider_change(evt:SliderEvent):void {
                sl.setStyle("labelOffset", evt.value);
            }
        ]]>
    </mx:Script>

    <mx:ApplicationControlBar dock="true">
        <mx:Form styleName="plain">
            <mx:FormItem label="labelOffset:">
                <mx:HSlider id="slider"
                        minimum="-20"
                        maximum="60"
                        value="-10"
                        snapInterval="1"
                        tickInterval="5"
                        liveDragging="true"
                        change="slider_change(event);" />
            </mx:FormItem>
        </mx:Form>
    </mx:ApplicationControlBar>

    <mx:HSlider id="sl"
            labels="[0,5,10]"
            tickInterval="1" />

</mx:Application>
