Show data points on a Flex

问题:

I'm using a graph with a <mx:LineSeries>. When I hover over the line it shows the data points as little circular points. How can I get these points to display all of the time?

回答1:

To turn off the datatips for a particular series, set the series.interactive property to false.

回答2:

If you're using <mx:LineSeries>, then set the following property:

itemRenderer="mx.charts.renderers.CircleItemRenderer"

When constructing a LineSeries in ActionScript, then set the itemRenderer style on your LineSeries object before adding to the series array:

lineSeries.setStyle("itemRenderer", new ClassFactory(mx.charts.renderers.CircleItemRenderer));

Don't forget to...

import mx.charts.renderers.*;

You don't have to stick to the circle item renderer either, you can use any of the item renderers found in the renderers package.

LineChart.showAllDataTips = true;
