Grafana Catalog

The plugin was updated in the Grafana Plugins catalog on September 11, 2023.

Data Manipulation Panel 3.2.1 for Grafana.

Date Time

Now you can impose the allowed minimum and maximum date by using the familiar built-in Grafana controls.

Impose minimum and maximum for the Date Time type.

Field Mapping

Following many community requests, we made field-to-form element mapping for the Data Source and Query initial request type more straightforward. Now you can do it using a new parameter that appears for every form element when the proper initial request type is selected.

Data Source

Explicitly specify the field-to-form element mapping for Data Source using a new parameter.

Query

Explicitly specify the field-to-form element mapping for Query using a new parameter.

Show If supports variables

Every form element has the Show If returned value is true parameter where you enter JavaScript code.

• If this code returns true, the element is shown on the panel.
• If this code returns false, the element is hidden from the panel.

Conditional visibility example.

Example code to check the current value of the select element and show the dateTime element if the value equal to max:

const select = elements.find((element) => element.id === "select");

if (select) {
  return select.value === "max";
}

In this release, we made it possible to use dashboard and global variables within your JavaScript code.

Conditional visibility using a dashboard variable example.

Example code to check the value of the dashboard variable var:

const test = replaceVariables('$var');
return test === 'test'

File Upload

For the File type, you can specify a list of allowed file extensions.

A new parameter for the File type - accepted file extensions.

Indication of loading in progress

If the data loading takes time, the Data Manipulation form will indicate that as follows.

Initial Request

The end user will see a running blue line at the top of the form.

A moving blue line indicates an initial request being in progress.

Update Request

All buttons are disabled and moving circled dots are placed instead of the Submit button icon.

Dots moving in a circle indicate an update request being in progress.

Custom Code

Custom code can be asynchronous. For that, the custom code should return the promise.

const getInitialData = async () => {
  const response = await fetch('http://123');

  const data = await response.json();

  /**
   * Update Elements with data
   */
  onChange([])
}

/**
 * Return Promise
 */
return getInitialData()

Radio and Select icons

Radio with Custom options element and two Select elements (Select with custom options and Multi Select with Custom options) have the Options parameter where you specify all possible choices that a user can make.

Starting from this release, every such choice in addition to type, value and label, now has an icon parameter. You can select from the standard Grafana icon list.

Icon is a new parameter.

Getting Started

You can install the Data Manipulation Panel from the Grafana Plugins catalog or using the Grafana command line tool.

For the latter, please use the following command:

grafana-cli plugins install volkovlabs-form-panel
