IcCube - Treemap Chart with duplicate names - google-visualization

Question

In the Google Treemap Chart every node has to have a unique id, but two nodes can have the same name (https://groups.google.com/d/msg/google-visualization-api/UDLD-a-0PCM/IwVCGzsWOg8J).
I used the schema from the parent/child demo (http://www.iccube.com/support/documentation/user_guide/schemas_cubes/dim_parentchild.php)
Using the following MDX statement in the treemap works, as long as the names of the nodes are unique:
WITH
MEMBER [parent_name] as IIF( [dim (ALL)].[Hierarchy].currentmember
is [dim (ALL)].[Hierarchy].[ALL],'',
[dim (ALL)]. [Hierarchy].currentmember.parent.name )
SELECT
{[parent_name],[Measures].[value]} on 0,
non empty [dim (ALL)].[Hierarchy].members on 1
FROM
[Cube]
If I added the line to the In-memory table in icCube's schema :
7,4,Spain, 2, 32
but the name Spain is double when rendering the Treemap. To support names a child definition in the GVI table should be something like this:
{v:'uniqueID-Spain', f:'Spain'}

As a workaround you can use the following code that modifies GviTable processing for the google tree widget. Check the example here:
https://drive.google.com/file/d/0B3kSph_LgXizSVhvSm15Q1hIdW8/view?usp=sharing
Report JavaScript:
function consumeEvent( context, event ) {
if (event.name == 'ic3-report-init') {
if(!_.isFunction(ic3.originalProcessGviTable)) {
ic3.originalProcessGviTable = viz.charts.GenericGoogleWidget.prototype.processGviTable
}
viz.charts.GenericGoogleWidget.prototype.processGviTable = function(gviTable){
if(this.props.ic3chartType === "TreeMap") {
gviTable = gviTable || this.gviTable();
var underlying = _.cloneDeep(gviTable.getUnderlyingGviTable());
_.each(underlying.rows, function(row){
// Replace id with parent prefixed
if(_.isObject(row.c[0]) && !_.isString(row.c[0].f)) {
row.c[0].f = row.c[0].v;
if(_.isObject(row.c[0].p) && _.isString(row.c[0].p.mun)) {
row.c[0].v = row.c[0].p.mun;
}
}
});
gviTable = viz.GviTable.fromSnapshot(underlying);
this.startColumnSelection = gviTable.getNumberOfHeaderColumns() - 1;
return viz.charts.toGoogleDataTableOneRowHeader(gviTable);
} else {
return ic3.originalProcessGviTable.apply(this, gviTable);
}
}
}
}
For the query like:
WITH
MEMBER [parent_name] as
IIF( [dim (ALL)].[Hierarchy].currentmember.isAll(),
'',
([dim (ALL)].[Hierarchy].currentmember.parent.uniqueName)
)
SELECT
{[parent_name],[Measures].[value]} on 0,
non empty [dim (ALL)].[Hierarchy].members on 1
FROM
[Cube]

This is a limitation of Google Treemap chart that is using the same column for the id and the label. Besides changing the names to ensure they are unique (e.g. adding the parent) I don't see a workaround to this.
An option would be using another Treemap chart (e.g. one from D3) that has not this limitation.

The schema is working (just use , instead of ; as separator )
--- icCube Reporting ---
The issue using Treemap is that you've two rows with the same id (Germany), fiddle
This fiddle is a running example of treemap
