Charting with Multiple Scenarios

To create a chart that displays data from more than one scenario, just use a scenario attribute on a vdl-chart-series element.
Set its value to the index of the scenario you wish to use as the source of the data.
<vdl-chart> 
  <vdl-chart-series type="bar" entity="FactorySupply" scenario="0"> 
    <vdl-index-filter set="Factories" value="New York"> 
    </vdl-index-filter> 
  </vdl-chart-series> 
  <vdl-chart-series type="bar" entity="FactoryDemand" scenario="1"> 
    <vdl-index-filter set="Factories" value="Paris"> 
    </vdl-index-filter> 
  </vdl-chart-series> 
<vdl-chart>
Pie charts are an exception to this principle, as multiple pie charts cannot be overlaid. In this case, you can draw multiple pie charts separately using the vdl-repeat attribute of vdl-chart, indexing through the scenarios as required.
<vdl-chart vdl-repeat="=s,i in scenarios" 
                    title="Multi-scenario, Multi-entity"> 
  <vdl-chart-series type="pie" entity="ServiceLevelAgreements" scenario="=i"> 
  </vdl-chart-series> 
</vdl-chart>
