Hello everyone,
I'm trying to create a custom visual based on D3's Visavail, the linked example defines two datasets: catagories and data:
var dataset = [{ "measure": "Fat Bike", "categories": { // category names and their colors defined here "Kim": { "color": "#377eb8" }, "Bert": { "color": "#ff7f00" }, "Zoe": { "color": "purple" }, }, "data": [ ["2016-01-01 12:00:00", "Kim", "2016-01-01 13:00:00"], ["2016-01-01 14:22:51", "Zoe", "2016-01-01 16:14:12"], ["2016-01-01 16:14:12", "Bert", "2016-01-01 17:14:12"], ["2016-01-01 19:20:05", "Zoe", "2016-01-01 20:30:00"] ] }];
Question:
how do I define two different tables in my dataViewMappings, one for the categories and one for the data?
Dataroles:
Here is a screenshot of my data, the chart is succesfully created with pre-defined data.
DataViewMapping:
Why is the datamapping below not creating two tables?
"dataViewMappings": [
{
"conditions":[
{
"DownTimes":{
"max": 3
}
}
],
"table": {
"rows": {
"for": { "in": "DownTimes" }
}
}
},
{
"conditions":[
{
"Begin":{
"max": 1
},
"End":{
"max": 1
},
"RedenIndex":{
"max": 1
}
}
],
"table": {
"rows": {
"select":[
{"for": { "in": "Begin" }},
{"for": { "in": "End" }},
{"for": { "in": "RedenIndex" }}
]
}
}
}
]
I included the total project folder: Here (zip)

Power BI Custom Visuals API does not support multi data view mappings.
You should use a single dataViewMapping to get all of data.
