### What problem does this feature solve? I am implementing a charting framework that should support interactivity between charts. For example, if a user selects (clicks) a specific value on a bar chart, the action should result in that value being emphasized, and any other chart on a dashboard that relies on a series that is itself based on the selected value (though the value might be groupped/displayed differently), should empahsise the corresponding portion of the series. The image below shows two charts, a bad chart and a pie chart, that both rely on a series of values. The bar charts displays the values stacked by category against months, the pie chart sums the categories and shows a percentage total.  Selecting a specific value on the bar chart should emphasize that bar component, as well as emphasize the corresponding portion of the series on the pie.  This should work when multiple values are selected also, as shown below.  Note: It sholud work analogously on a bar chart. ### What does the proposed API look like? ```typescript let options = { ... series: [ { data: [100, 50, 50], emphasiedData: [15, 0, 0], // New: This is the data that will be emphasized against the original data above } ] } ``` -- This is an automated message from the Apache Git Service.
