I am creating a custom filter in power bi. My basic idea is say, I have two categories "Category and Segment" , which has following values. Category -> Technology,Office Supplies, Furniture. Segment -> Consumer, Corporate, Home Office. and when user want to filter charts based on any of these values he clicks on appropriate buttons.(each value would be a button). How to achieve this?
I have been able to do create a custom filter for one category.When I put two categories filter does not work.
Here is the result with one category -
This works exactly with three distinct values.
But when we add one more category power bi's Grouping issue comes. Meaning now the grouping is between category and segment and so nine distinct values comes. From power bi perspective its correct but what I am expecting is 6 values only , no grouping between each other.
How to overcome this?
-- Codes -- getting data.
let viewModel: ViewModel = {
dataPoints: []
};
if (
!dv ||
!dv[0] ||
!dv[0].categorical ||
!dv[0].categorical.categories ||
!dv[0].categorical.categories[0].source
// || !dv[0].categorical.values
)
return viewModel;
let view = dv[0].categorical;
let categories = view.categories[0];
console.log("Categories:-");
console.log(categories);
// for (let j = 0; j < categories.length; j++) {
for (let i = 0, len = categories.values.length; i < len; i += 1) {
viewModel.dataPoints.push({
category: <string>categories.values[i],
identity: this.host
.createSelectionIdBuilder()
.withCategory(categories, i)
.createSelectionId()
});
}
// }
return viewModel;
-- saying to power bi to slice
__this.selectionManager.select(element.identity);
where element is each button
What I am expecting is how many ever category we put they don't group each other rather gives back distinct values of each category and for all these a button would be there. On clicking the button it filters the chart.
