Not able to define variable in FeedItem

Hi All,

We are using vizFrame to display a chart. The chart has 4 measures ms1, ms2, ms3 and ms4.

However, not all of them need to be displayed. Based on the checkboxes that user selects, we want to switch ON / OFF a particular measure from the graph.

For this we are using the following statement in the controller on Checkbox Press:-

var yaxis = '["ms1", "ms3"]'; <- This variable is updated based on checkboxes selected

var feedValueAxis = new sap.viz.ui5.controls.common.feeds.FeedItem({

'uid': "valueAxis",

'type': "Measure",

'values': [yaxis]

}),

Issue :-

We get an error message ""Failed to update chart 50014 : Feed "ms1 , ms3" could not accept more containers.

Looks like it expects the actual measures to be mentioned in the 'values' property and not a variable name.

Any idea on how to specify values to the FeedItem through a variable name ?

Note - When we write the following lines of code then everything seems to work fine, but it doesn't serve our purpose :-

var feedValueAxis = new sap.viz.ui5.controls.common.feeds.FeedItem({

'uid': "valueAxis",

'type': "Measure",

'values': ["ms1", "ms3"]

}),

Thanks,

Ashish
