I have created a custom property for a measure in my extension
CustomMeasureProp:{
type:"string",
label:"Custom Measure Property",
ref:"customMeasureProperty",
expression: "optional"
}
In the QlikSense Desktop I am able to add my extension and see the custom property when adding my measure.
I populate it with my EXPRESSION Max(value).
THE QUESTION.
How do I access that evaluated expression through the api?
I have used my code
$scope.backendApi.getProperties().then(function(reply){
angular.forEach(reply.qHyperCubeDef.qMeasures,function(measure){
console.log('MEASURE',measure);
if(typeof measure.customMeasureProperty!=='undefined'){
console.log('MEASURE LABEL', measure.customMeasureProperty);
}
});
Rather than returning the evaluated expression when looking at the object measure.customMeasureProperty, it returns the string Max(value).
So how do get the evaluated value?
colorExpression:{
type: "string",
label: "Enter color expression",
ref:"qHyperCubeDef.qDimensions.0.qAttributeExpressions.0.qExpression",
expression:"optional"
}
how do I call this ref: qHyperCubeDef.qDimensions.0.qAttributeExpressions.0.qExpression", in function
I don't think that expression is valid. But I'm not sure.
It looks like you are trying to specify exactly where the evaluated expression will go within the HyperCube. But, Qlik is smart enough to put it where it is supposed to go as long as you use the correct format. As I mentioned in the post above yours, using, "qAttributeExpressions.0.qExpression" will put an evaluated expression in the HyerCube, but you'll have to go digging for it a bit (refer to my trace above).
But, maybe your expression will work, I don't know.
Hello Sir,
I want to add Custome coloe property to dimention.
I have written this code inside of dimention shown below:
definition : {
type : "items",
component : "accordion",
items : {
dimensions : {
uses : "dimensions",
min : 1,
items: {
colorExpression:{
type: "string",
label: "Enter color expression",
ref:"qAttributeExpressions.0.qExpression",
expression:"optional"
}
}
},
now please tell me what should I need to write inside of function
paint: function ($element,layout) {
this.backendApi.eachDataRow( function (rownum, row){
var dimIndex = 0; // you are putting the value in your first dimension
row[dimIndex].qAttrExps.qValues[0].qText;
});
if ( !this.$scope.table ) {
this.$scope.table = qlik.table(this);
}
return qlik.Promise.resolve();
}
but Sir , this is not working for me.
please give me any solution

Hello Sir,
My name is Humesh . I am developing an extention for table.I want to add custome color property to every dimentions and measures.
I found your this code :
colorExpression:{
type: "string",
label: "Enter color expression",
ref:"qAttributeExpressions.0.qExpression",
expression:"optional"
}
I have written this code inside of dimention shown below:
definition : {
type : "items",
component : "accordion",
items : {
dimensions : {
uses : "dimensions",
min : 1,
items: {
colorExpression:{
type: "string",
label: "Enter color expression",
component : "expression"
ref:"qAttributeExpressions.0.qExpression"
}
}
},
now please tell me what should I need to write inside of function
to apply custome color reference to dimention
paint: function ($element,layout) {
// what should I write here
if ( !this.$scope.table ) {
this.$scope.table = qlik.table( this );
}
return qlik.Promise.resolve();
}
please give me solution
Over here. You already asked this.
Yes Sir,
I am really Sorry for this.
but I am not getting any solution for this.
Can you share any example for custome color property to dimention or measure ...
I'm not exactly sure how to help you. Please refer to the other thread since I provided more information there.
Re: Set color by expression in extension
But, here is my full code where I use dimensions to evaluate color expressions:
