Keep, remove, drill sections

Learn how to apply 'Keep', 'Remove', and 'Drill' actions using postMessage API for dynamic, interactive data exploration.

On right click of any chart in a Vizpad, you will get three options:

• Keep (refers to maintaining a section)

• Remove (refers to removing a section)

• Drill (drilling down to get insights)

Keep, remove, and drill options

Keeping a section of chart

telliusFrame.postMessage({
         actionType: "filterBySelection",
         vizId: vizId,
         selectionPointType: "single", // single or multiple
         values: value,
         filterType: "Keep",
         columns: columnName
       }, "*");

Removing a section of chart

telliusFrame.postMessage({
         actionType: "filterBySelection",
         vizId: vizId,
         selectionPointType: "single", // single or multiple
         values: value,
         filterType: "Remove",
         columns: columnName
       }, "*");

selectionPointType refers to single or multiple point selection with the filter on a particular data value or multiple data values respectively. The values can be either be “single” or “multiple”.

Drilling a Viz

We can drill down a viz by:

1. Column Name

2. Hierarchy

3. Across another vizpad

Drilling a column

Drill by column name

telliusFrame.postMessage({
    actionType: "drillByColumn",
    vizId: "0d4abe5e-0758-4bdd-a71c-14e5f9d9a2b0",
    drillByColumn: "Gender",
    filters: [{
        value: "Desktop",
        column: "Device_Type",
        operator: '='
    },
    {
        value: "Direct",
        column: "Source",
        operator: '='
    }]
}, "*");

Drill by hierarchy

telliusFrame.postMessage({
    actionType: "drillByHierarchy",
    vizId: "0d4abe5e-0758-4bdd-a71c-14e5f9d9a2b0",
    drillByColumns: ["county_name", "state_name"],
    filters: [{
        value: "Desktop",
        column: "Device_Type",
        operator: '='
    },
    {
        value: "Direct",
        column: "Source",
        operator: '='
    }]
}, "*");
