And here is the mxml for this chart:
<ns2:ECharts id="chart">
<ns2:chartOptions>
<ns2:EChartsOptions>
<ns2:title>
<ns2:Title text="Sales vs. Profit" show="true"
link="https://ecomfe.github.io/echarts-examples/public/index.html"; target=
"_self" />
</ns2:title>
<ns2:xAxis>
<ns2:XAxis data="{this.data}" position="top" />
</ns2:xAxis>
<ns2:yAxis>
<ns2:YAxis/>
</ns2:yAxis>
<ns2:seriesList>
<ns2:SeriesList>
<ns2:series>
<fx:Array>
<ns2:Series name="Sales" type="bar" data="{this.salesData}" />
<ns2:Series name="Profit" type="line" data="{this.profitData}" />
</fx:Array>
</ns2:series>
</ns2:SeriesList>
</ns2:seriesList>
</ns2:EChartsOptions>
</ns2:chartOptions>
</ns2:ECharts>
Couple of questions:
1. I would like to provide a drop down of options for some properties like
Series.type like "bar", "line", etc. I believe you could do that in Flex
using the [Inspectable] metadata tag. Does Royale support that?
2. The above mxml, though works fine, seems a bit too verbose. Is it
possible to specify default properties via the DefaultProperty metadata tag?
For example, if SeriesList had this tag: [DefaultProperty("series")],
we could simplify the seriesList element as:
<ns2:seriesList>
<ns2:SeriesList>
<fx:Array>
<ns2:Series name="Sales" type="bar" data="{this.salesData}" />
<ns2:Series name="Profit" type="line" data="{this.profitData}" />
</fx:Array>
</ns2:SeriesList>
</ns2:seriesList>
