custom visual adding dataview table

[Anonymous]

Hi,

im using this custom visual template :  https://github.com/microsoft/powerbi-visuals-gantt/blob/master/capabilities.json

This works fine! 

In addition to the categorical filter i need to insert data without filtering, thats why i need an additional table!? 

The Import data has only one column and 10 rows.

Just to be clear: An array in code with 10 indeces could solve this! 

What i tried:

I add a new field "mydataset" to role and table to the existing capabilities.json

But i cant acces my data: -> "dataView.table "is null

{
    "dataRoles": [
        {
            "name": "Legend",
            "displayName": "Legend",
            "displayNameKey": "Role_Legend",
            "kind": "Grouping"
        },
        {
            "name": "Task",
            "displayName": "Task",
            "displayNameKey": "Role_Task",
            "kind": "Grouping"
        },
        {
            "name": "My Data Set",
            "displayName": "mydataset",
            "displayNameKey": "Role_mydata",
            "kind": "Grouping"
        },
        {
            "name": "Parent",
            "displayName": "Parent",
            "displayNameKey": "Role_Parent",
            "kind": "Grouping"
        },

"matrix" : null,

"table" : null,

...

categorical: {...}

Edit:

I think is not possible to use more then one dataviewmapping like categorical and table.

Please let me know if I'm wrong.

Thanks

Hi @Anonymous,

You can only use one dataViewMapping in a custom visual, so you need to think about which one best suits your need to get the data into the visual to begin with. Once it's in there, you can transform it into a suitably-shaped view model to fit your visual logic.

If you're able to provide an overview of what your goals are, I might be able to suggest what your dataViewMapping and dataRoles need to look like. From where you're starting off, it looks like you're trying to produce gantt-like functionality? If you have any sample data and what your expected output is, this would be a great help in figuring out the best way to assist. Custom visuals can be somewhat open-ended so anything that can clarify what success looks like will hopefully avoid as much ambiguity up-front as possible.

Cheers,

Daniel

Hi,

thanks for support.

The Date is filtered with a timeline slicer. This causes my records to be filtered by date as well.

But I need in my custom visual additional records that are not filtered by date but by another value. Like the option "Show item with no data" but this has no effect, on my datarole field

Example:
I need to visualise the "blue" entries -this works!

But i also need entries only filtered by Table2.Teams ("green").  How can I access the same Team (blue  green) entries without being affected by the date filter?

Table1

Name	Task	Starttime	Endtime	Team
Testuser1	Task1	1/12/2019	20/12/2019	Team1
TestUser1	Task2	22/12/2019	30/12/2019	Team1
TestUser3	Task0	1/11/2019	3/11/2019	Team1
TestUser2	Task7	1/11/2019	3/11/2019	Team2

Table2

TeamName	additonal fields
Team1	entry1
Team2	entry2

You right its better to rebuild the whole model.

In my case i found a way to solve this,  i changed  "group" by selection from Legend to Task.

Now data is no longer filtered by legend but it my case that helps and i get all the records I need.

"values": {
                    "group": {
                        "by": "Task",
                        "select": [
                            {
                                "for": {
                                    "in": "EndDate"
                                }
                            },
                            {
                                "for": {
                                    "in": "Duration"
                                }
                            },
                            {
                                "for": {
                                    "in": "Completion"
                                }
                            }
                        ]
                    }
                }
            }
