qHyperCubeDef
Most visualizations that come built-in with Qlik Sense are based on a hypercube
definition (qHyperCubeDef
) on root level. A hypercube can contain both
dimensions and measures. If selections are applied to a hypercube, only the
selected values are displayed.
You can have multiple hypercubes in your properties (initialProperties
). This
allows you to make advanced visualizations that combine several data sets.
If you have multiple hypercubes, you need to place them at different paths in
your property structure.
Examples
Example: Hypercube definition in Chart template
initialProperties: {
version: 1.0,
qHyperCubeDef: {
qDimensions: [],
qMeasures: [],
qInitialDataFetch: [{
qWidth: 2,
qHeight: 50
}]
}
},
Example: Multiple hypercubes definition
initialProperties : {
version : 1.0,
qHyperCubeDef : {
qDimensions : [],
qMeasures : [],
qInitialDataFetch : [{
qWidth : 10,
qHeight : 50
}]
},
second : {
qHyperCubeDef : {
qDimensions : [],
qMeasures : [],
qInitialDataFetch : [{
qWidth : 10,
qHeight : 50
}]
}
}
}
Example: Enabling numerical sorting
By defining qInterColumnSortOrder
, numerical sorting on the measure is enabled.
If you define qInterColumnSortOrder
in initialProperties
, you must also define
the qDimensions
and qMeasures
being used, else an error will be thrown.
initialProperties : {
qHyperCubeDef : {
qDimensions : [{
qDef : {
qFieldDefs : ["Dim1"]
}
}
],
qMeasures : [{
qDef:{
qDef : "=Sum(Expression1)"}
}
],
qInterColumnSortOrder : [1,0],
qInitialDataFetch : [{
qWidth : 10,
qHeight : 50
}]
}
},
