Setting parameters through URL

In Cloudera Data Visualization, setting parameters through the URL allows you to dynamically add selection options without altering the app's saved values. These settings can also be easily shared by including them in emails, documents, or similar mediums.

The basic syntax for URL formatting:

http://baseurl/arc/apps/app/id?config.output={setting: value}

baseurl: The IP address of the site, such as 27.0.0.1:8000, or sf.mycompany.org.
id: Unique number of the dashboard or the visual.
output: The output of the parameter or the picklist.
setting: The available option is VALUE.
value: An array of value-label pairs in the format [["value1","label1"],["value2","label2"],["value3","label3"], ...,].

The following steps demonstrate how to use parameters through URLs:

On the Values tab of the Settings modal window, specify the Title and Output Parameter.
In this example, test and result are used, respectively.
Optional: You can specify one or more Value:Label pairs.
In this example, result1:1 is used.
Click APPLY.
In the dashboard, check the possible options for the parameter.
In the test parameter, click the Down Arrow icon.

There are two options: (All) and 1.
Select 1 and hover the pointer over the Filter icon at the top right of the dashboard.

The Current Parameters are set to result: result1 and result.alias: 1.
Save the dashboard.
Switch to View mode.
Copy the URL.

In this example, it is http://127.0.0.1:8000/arc/apps/app/38.
In another browser window, paste the value saved in the previous step, add the code specific to setting parameters through URL, and click enter.
In this example, two more pairs: result2:2, and result3:3 are added. The new code is in bold font, starting with '?'.
```
http://127.0.0.1:8000/arc/apps/app/38?config.result={values:[["result2","2"],["result3","3"]]}
```
In the dashboard, check the possible options for the parameter.

Options 2 and 3 appear in the selection list.
In the test parameter, click Select.

There are two additional options: 2 and 3.
Select 2 and hover the pointer over the Filter icon at the top right of the dashboard.

Current Parameters are set to result: result2 and result.alias: 2.
