Description
According to this example: http://archive.dojotoolkit.org/nightly/dojotoolkit/dojox/charting/tests/test_nulls.html the charting component is capable of plotting null-values as gaps.
I am getting values from a JsonRest? Store with a StoreSeries? in the form [{"timestamp": 1315692000000.0, "value": 43.137300000000003}, {"timestamp": 1315692300000.0, "value": 42.981199999999994}]
But how can I pass null-values to a StoreSeries?? I have tried the following: [{"timestamp": 1315692000000.0, "value": 43.137300000000003}, {"timestamp": 1315692000000.0, "value": null}, {"timestamp": 1315692300000.0, "value": 42.981199999999994}] => null is plottet as 0 (zero)
[{"timestamp": 1315692000000.0, "value": 43.137300000000003}, null, {"timestamp": 1315692300000.0, "value": 42.981199999999994}] => gives no plot and the following error message in Firebug: TypeError?: _7 is null (I am using release-1.7.0b5)
'timestamp' and 'value' are defined as x- and y-axis values.
Is there another way to pass null-values to a StoreSeries??
This is a duplicate of #6812
Null values are supported only for index based data sets [ y1, y2... , null, yn] not for {x,y} data set. Obviously this must be improved and work will be done in the context of the #6812 ticket.
