Post Message Filters

Introduction

This allows user to filter data using a json object.

Steps to connect to tellius

  1. To connect to Tellius app, embedding app (in this case  Teletrac) need to Post a message called INITIALIZE after the app is loaded.
  2. Tellius app will respond back with a message called TELLIUS_INITIALIZED . This is useful to  Validate that the received message is from Tellius and communicate further.
  3. Once TELLIUS_INITIALIZED is received, filters can be applied.

Example:

var telliusFrame;    document.querySelector("iframe").addEventListener("load", function() {
    telliusFrame = document.getElementsByTagName("iframe")[0].contentWindow;        telliusFrame.postMessage('INITIALIZE', "*");        
})
function receiveMessage(event) {
    if(event.data === 'TELLIUS_INITIALIZED') {
        telliusFrame.postMessage ({actionType: "filterBySelection",vizId:
        "f7931a1e4-a9b2-4966-95ad-138c8d0f278c", selectionPointType: "single", 
        values: "Standard Class", filterType: "Keep", columns: "Ship_Mode"},       
        "*");
    }
}
window.addEventListener("message", receiveMessage, false);

Steps to reproduce in our App

  1. Copy link from Share button available in Vizpads in the top bar.
    A popup will appear.
  2. Change the mode from “Can View” to “Can Edit” under the Embed URL section. Hit the Copy button.
    The Structure of URL is “https://dev.app.tellius.com/explore/view/<vizpad id>/?access=edit&datasetId=<dataset id>&jwt=<token>”
    URL Structure breakdown :“https://dev.app.tellius.com” is the website url
    "/explore/view/” is to be not modified as this is an app specific url extension for vizpads
    <vizpad id> is the unique vizpad id.
    access=edit refers to edit mode. There are two modes : “edit” and “read”.
    “datasetId=<dataset id>” refers to the unique dataset id - not mandatory.
    jwt=<token> refers to the login credentials or token for security and login purposes.
    You can copy the given link (it would work until the session of JWT token expires)
    for example:
    https://dev.app.tellius.com/explore/view/3b7b372d-8784-42ac-a26c-3fdd77ea79d9/?access=edit&datasetId=load_7b3b1e7a-71ec-4631-89b1-ae53a796892f&jwt=eyJhbGciOiJIUzUxMiIsInR5cCI6IkpXVCJ9.eyJhdWQiOiJ7XCJ1c2VybmFtZVwiOlwiYW5hbmRoXCIsXCJyb2xlXCI6XCJhZG1pblwiLFwiaWRcIjpcIjNiMjJmOTZmLTAyZWMtNDFjNi1iMWMzLWIzNzQyMTk3ODIzOVwiLFwiZ3JvdXBzXCI6W3tcInJvbGVcIjpcInBvd2VyXCIsXCJuYW1lXCI6XCJncm91cDFcIixcImlkXCI6XCJhNDYzMjRiMC1mZDA3LTQyZTMtYmI5Zi0yNDY1ZGNjYTNiNzhcIn1dLFwiZW1haWxcIjpcImFuYW5kaC5rdW1hckB0ZWxsaXVzLmNvbVwifSIsImV4cCI6MTU2NzE0MDI1OSwiaWF0IjoxNTY0NTQ4MjU5LCJpc3MiOiJUZWxsaXVzTWlkZGxld2FyZSIsImp0aSI6ImIzNTE3NjI2LThlZjAtNGQ3Mi1iYTE1LTc5Mjg2NTM3NDAxYSIsInBlbSI6e30sInN1YiI6IntcInVzZXJuYW1lXCI6XCJhbmFuZGhcIixcInJvbGVcIjpcImFkbWluXCIsXCJpZFwiOlwiM2IyMmY5NmYtMDJlYy00MWM2LWIxYzMtYjM3NDIxOTc4MjM5XCIsXCJncm91cHNcIjpbe1wicm9sZVwiOlwicG93ZXJcIixcIm5hbWVcIjpcImdyb3VwMVwiLFwiaWRcIjpcImE0NjMyNGIwLWZkMDctNDJlMy1iYjlmLTI0NjVkY2NhM2I3OFwifV0sXCJlbWFpbFwiOlwiYW5hbmRoLmt1bWFyQHRlbGxpdXMuY29tXCJ9IiwidHlwIjoiYWNjZXNzIn0.gbSOZVqhqORoyVk_9yrZ4Bz-NKJjhhqDxVegs3q17hN0G70yNyiS2_LM9eJtPkDD0GA3_Z-PzTKrkGARQjdBlA
  3. Go to Embedded App (http://34.201.98.2:32543/) and click on Vizpad button.
  4. Paste the copied link in the textbox and wait till the vizpad is loaded.
    Please refer the image below :
  5. Enter the column name you want to filter upon.
  6. Now drag and select data values on the chart and then select any button for desired operation.
    Dragging and selecting bars “Pen” and “Pen Set”:
    Resulting Chart:

Format

Single Filter

Remove:
{
    actionType: "filterBySelection",
    vizId: <vizId>,
    selectionPointType: "single",
    values: <values>,
    filterType: "Remove",
    columns: <columnName>
};
Keep:
{
    actionType: "filterBySelection",
    vizId: <vizId>,
    selectionPointType: "single",
    values: <values>,
    filterType: "Keep",
    columns: <columnName>
};

Multiple Filter

Keep:
{
    actionType: "filterBySelection",
    vizId: <vizId>,
    selectionPointType: "multiple",
    values: <values>,
    filterType: "Keep",
    columns: <columnName>
};
Remove:
{
    actionType: "filterBySelection",
    vizId: <vizId>,
    selectionPointType: "multiple",
    values: <values>,
    filterType: "Remove",
    columns: <columnName>
};
Note: The user who is embedding the app, will get <vizId>, <values>, and <columnName> from the child app.

“actionType” can be categorized by “drillByColumn”, “drillByHierarchy”, “filterBySelection” and others yet to come. It means the type of action user wants to take on vizs. For Filters we use “filterBySelection”.

“selectionPointType” refers to single or multiple point selection with filter on a particular data value or multiple data values respectively. Please refer the examples given below. It can be either “single” or “multiple”.

Examples

For Single Keep Filter the object will be like
{
    actionType: "filterBySelection",
    columns: "Item",
    filterType: "Keep"
    selectionPointType: "single",
    values: "Pen",
    vizId: "2f79721a-07ab-43e2-b8ad-7f4e29a268bf"
}
For Multiple Keep Filter the object will be like
{
    actionType: "filterBySelection",
    columns: "Item",
    filterType: "Keep",
    selectionPointType: "multiple",
    values: [“Pen”, “Pen Set”],
    vizId: "2f79721a-07ab-43e2-b8ad-7f4e29a268bf"
}

Tracking filters using window communication service

We use window.postmessage for the communication between the Tellius(embedded app) and the embedding App.

The communication can be both ways, one from embedding app(i.e Teletrac) to embedded app(i.e Tellius) and vice versa.

  1. For the embedding app to communicate to the embedded app please refer this.
  2. For the Embedded app to communicate to the embedding app, .Embedding app needs to have eventLister to receive this message. For every Point click in the chart, Area selection or highlighting the chart Tellius will post a message to the embedding app.

	    value: {
	        start: "2014-02-18T00:00:00Z",

	}
]}

TelliusEx1c

{actionType: "resolution", timeColumn: {resolution: "quarterly", }}

List of BusinessView columns

To get List of columns as a part of the window message, we need to set actionType as getBusinessViewColumns.  

Example:

{actionType: "getBusinessViewColumns"}

Embedding app will receive columns info as follow:

{ columns: ["List of columns info"], columnNames: ["list of columnNames"], actionType: "BVCOLUMNS",}

Remove Filters

Remove Normal Filter

  1. To remove applied filters from Vizpad we need to set actionType as removeVizpadFilter
    Ex:
    { actionType: "removeVizpadFilter", filters: [{value: "Same Day", column: "Ship_Mode", operator: "=" }]}
  2. To remove applied filters from Viz we need to set actionType as removeVizFilter
    Ex: 
    { actionType: "removeVizFilter", filters: [{vizId: "ed198301-5c74-4aa0-8e17-83838681dc49", value: "Same Day", column: "Ship_Mode", operator: "=" }]}

Remove IN/NOT IN Filter

**Here value field must be array

telliusFrame.postMessage({actionType: "removeVizpadFilter", filters: [{ value: ["Same Day"], column: "Ship_Mode", operator: "Not in"}]}, "*");

REMOVE VIZPAD/VIZ TIMELINE FILTER

telliusFrame.postMessage({actionType: "removeVizpadFilter", filters: [{ value: "last 6 years", column: "Order_Date", filterKind: "vizpadTimelineFilter"}]}, "*");

To enable voice based search, we need to add add one queryParameter called:

allow="microphone;"

Example:

<iframe class="telliusEmbedding"  height="500px" width="1200px" src={src} allow="microphone;"></iframe>

How did we do?
