I am wondering how will i proceed with the following requirement. I need to create a line chart of business data of the last 8 quarters. It is easy, but the requirement is that, there should not be a connection between last year's Q4 and this years Q1. In effect, using the same array collection i need to split the line chart so开发者_StackOverflow中文版 that it looks like two diffferent lines on the same chart. Any idea how to proceed with it.
Thanks, PK
First, you can add multiple line series by a criteria in your Array Collection:
<mx:series>
<mx:LineSeries
yField="Profit"
displayName="Profit"
/>
<mx:LineSeries
yField="Expenses"
displayName="Expenses"
/>
</mx:series>
You can change the width and color of the lines for each series by using the tag. Making each line a different stroke and color.
