Hello,
How would i go about designing the capabilities.json file if i want to add 3 related tables to a custom visual, at first i thought i should use tables but the api limits it to one..
I am trying to send somthing like this
Person:
personId
PersonName
Events:
personId
EventName
EventStart
EventEnd
The two tables are linked via personId.
I thought something like this:
But categories cannot be an array?
Thanks

Hi @AdamWhittaker,
Because categories can have other potential properties (like dataReductionAlgorithm), you would add a select property with an array to your existing object and include the data roles there (like you have done for values). The following should work based on your above definition (or get you close to it - it's a valid pattern that I have used in other visuals):
{
"dataViewMappings": [
{
"categorical": {
"categories": {
"select": [
{
"for": {
"in": "resourceId"
}
},
{
"for": {
"in": "resourceName"
}
},
{
"for": {
"in": "territory"
}
},
{
"for": {
"in": "eventColor"
}
}
]
},
"values": {
"select": [
{
"bind": {
"to": "eventId"
}
},
{
"bind": {
"to": "eventName"
}
},
{
"bind": {
"to": "manager"
}
},
{
"bind": {
"to": "appointmentNumber"
}
},
{
"bind": {
"to": "status"
}
},
{
"bind": {
"to": "description"
}
},
{
"bind": {
"to": "startDate"
}
},
{
"bind": {
"to": "endDate"
}
}
]
}
}
}
]
}
Good luck!

@dm-p Thanks for the help, it worked. Looks like i just missed the select part in:
