aps/Gauge¶

Displays a level of a resource usage.

A gauge shows one of 3 states: normal, warn, and over. This is useful for indicating resource usage status.

Overview ¶

With the aps/Gauge widget, you can display the usage of a resource.

Find the nested rules for this widget in the recommended Widget Hierarchy.

You can dynamically change the widget’s value or bind it with a data model. The length and color of the progress bar will automatically change after each change of the widget’s value. You can also bind the information displayed next to the progress bar with the data contained in the widget with help of standard template syntax. In this case the information will also change automatically after each change of the widget’s value.

Examples ¶

Declaration Through Loader¶

RUN DEMO

require(["aps/load", "aps/ready!"],
function(load) {
    "use strict";
    load(["aps/Panel", [
        ["aps/Gauge", {
            legend: "Disk usage",
            value: 30
        }],
        ["aps/Hr", { visible: true }],
        ["aps/Gauge", {
            legend: "Memory usage",
            value: 80
    }]]]);
});

Programmatic Declaration¶

RUN DEMO

require(["aps/Gauge", "aps/Panel", "aps/PageContainer", "aps/ready!"],
  function(Gauge, Panel, PageContainer){
    "use strict";

    var page = new PageContainer({}, "simpleGauge");
    var panel = new Panel();
    panel.addChild(new Gauge({
      label:      "Disk Usage",
      legend:     "${value} of ${maximum} GB used",
      minimum:    0,
      maximum:    500,
      value:      300,
      classesMap: {
              "200": "warn",
              "400": "over"
      }
    }));
    page.addChild(panel);
    page.startup();
});

unknownUsageText	string	${maximum} ${unitText} total	If the value property is undefined then the widget shows the unknownUsageText.
unlimitedText	string	${value} ${unitText} used (Unlimited)	If the maximum property is undefined then the widget shows the unlimitedText instead of the bar.
value	number	0	Absolute value of the scale.

classesMap object¶

Ratio values mapped to gauge lights.

{ "20": "warn", "25": "over" }
Default value: {'0%': '', '37%': 'warn', '62%': 'over'} - PCP / CCP v1,
{'0%': 'progress-bar-success', '37%': 'progress-bar-warning', '62%': 'progress-bar-danger'} - CCP v2.
These are gauge marks representing the boundary values of resource usage levels.

There are three usage levels. The default widget style is applied for the first level.

The “warn” CCS class is applied for the second level. And for the third, it is the “over” class. The value of this property must be an associative array with keys “warn” and “over” and values which are the boundary values.

disabled boolean¶

Specifies if the widget will respond to user input.

Default value: false.

gridSize string¶

This specifies the widget width that is relevant only for widgets inside Container, FieldSet, or Tiles. In other cases it will be ignored.

gridSize string contains few options with number values (from 1 to 12) separated by spaces, which specify the grid size of the widget in different layouts:

- md - desktop

- xs - phone

For example, gridSize: “md-4 xs-2”.

All values below 1, e.g. “md-0”, will be replaced with the empty string (“”), values above 12, e.g. “md-14”, will be reduced to 12 (“md-12”).

Default value: undefined.

isBusy boolean¶

If the widget is busy then this property is true.

Default value: false.

label string¶

Text that is shown as a label if the widget is placed inside a aps/FieldSet.

Default value: “”.

legend sting¶

Legend or description of a gauge. Default value: “” - PCP / CCP v1, “${value} of ${maximum} ${unitText} used” - CCP v2.

maximum number¶

Maximum value. Default value: 100. If maximum set to 0 then will be show only noneText instead of a bar itself. If maximum set to undefined then will be show only unlimitedText instead of a bar itself.

minimum number¶

Minimum value. Default value: 0.

noneText string¶

if the “maximum” property is 0 then the widget shows the noneText string. Default value: “None”

percent string readonly¶

Scale value in %. Calculated from value. Default value: “0%”

precision number¶

Percents precision. Default value: 2 - PCP / CCP v1, 0 - CCP v2.

unitText string¶

Presents the unit of measure. Default value: “”.

unknownUsageText string¶

If the value property is undefined then the widget shows the unknownUsageText. Default value: “${maximum} ${unitText} total”.

unlimitedText string¶

If the maximum property is undefined then the widget shows the unlimitedText instead of the bar. Default value: “${value} ${unitText} used (Unlimited)”.

value number¶

Absolute value of the scale. Default value: 0. For some resource types, the usage information may not be relevant at all. For example, in a VPS, RAM and CPU usage fluctuates significantly, and there is no sense in displaying the usage to a customer in context of billing information. In this case, the “undefined” value should be assigned to the “value” property to show only the “maximum” amount of the resource that the VPS can use.

visible boolean¶

If this property value is set to true, then the widget is visible.

Default value: true.

width number¶

Scale width used in PCP / CCP v1 only. Default value: 200 - PCP / CCP v1, 0 - CCP v2. It can be defined by a number or by a string. The latter must be a correct value for the HTML attribute width, that is either it contains a unit of measure or it is assigned the key-word “auto”. In CCP v2, use gridSize instead.

Public Methods ¶

METHOD	RETURN	DESCRIPTION
cancel ()	object	Sets the isBusy property to false
destroy ()	undefined	Destroys this widget
get ()	any	Get a property of the Stateful instance
getParents ()	array	Discover and return all parents of the widget
placeAt ()	dijit/_widgetbase function	Place this widget somewhere in the DOM based on standard dojo/dom-construct::place() conventions
set (name)	function
startup ()	undefined	Gets started after the DOM fragment is added to the document

cancel¶

Sets the isBusy property to false.

Return: object

destroy¶

Destroys this widget. Will also destroy any resources (including widgets) registered via this.own(). This method will also destroy internal widgets such as those created from a template.

Return: undefined

get¶

Get a property of the Stateful instance. Get a named property of the Stateful object. The property may potentially be retrieved via a getter method in subclasses.

In the base class, this just retrieves the object’s property.

Return: any

getParents¶

Discover and return all parents of the widget.

Return: array

placeAt¶

Place this widget somewhere in the DOM based on standard dojo/dom-construct::place() conventions. A convenience function providing a simple shorthand mechanism to put an existing (or newly created) widget somewhere in the DOM, and allow chaining.

Return: dijit/_widgetbase function

set¶

Return: function

ARGUMENT	TYPE	DESCRIPTION
`name`	undefined

startup¶

Gets started after the DOM fragment is added to the document Called after the widget and its children have been created and added to the page, and all related widgets have finished their create() cycle, up through postCreate().

Note that startup() may be called while the widget is still hidden, for example if the widget is inside a hidden dijit/Dialog or an unselected tab of a dijit/layout/TabContainer. For widgets that need to do layout, it’s best to put that layout code inside resize(), and then extend dijit/layout/_LayoutWidget so that resize() is called when the widget is visible.

Return: undefined

Public Events ¶

EVENT	RETURN	DESCRIPTION
onClick ()	undefined	The method is called when a user clicks on the widget

onClick¶

The method is called when a user clicks on the widget.
