Alternating background column colors in a Flex LineSeries chart
November 19, 2007Charting, LineChartlabelFunction, verticalAlternateFill, verticalFill
In a previous example, “Alternating background row colors in a Flex LineSeries chart”, we saw how to alternate row colors in a LineSeries chart using the horizontalFill and horizontalAlternateFill styles.

In the following example, we see a similar technique for setting column background colors using the verticalFill and verticalAlternateFill styles, as seen in the following snippet:

<mx:LineChart showDataTips=true dataProvider={dp}>

    <mx:backgroundElements>
        <mx:GridLines direction=vertical>
            <mx:verticalFill>
                <mx:SolidColor color=haloBlue alpha=0.2 />
            </mx:verticalFill>
            <mx:verticalAlternateFill>
                <mx:SolidColor color=haloSilver alpha=0.2 />
            </mx:verticalAlternateFill>
        </mx:GridLines>
    </mx:backgroundElements>

    ...

</mx:LineChart>
In this example, you also see examples of setting custom label functions for a LinearAxis and CategoryAxis, both of which we’ve seen examples of before (“Creating a custom label function on a Flex LineChart control’s linear axis” and “Creating a custom label function on a Flex LineChart control’s category axis” respectively) but it’s always fun to see a few of these things in a single example.
