Angular Material - Progress Bars

The md-progress-circular and md-progress-linear are Angular progress directives, and are used to show loading content message in application.

Attributes - md-progress-circular

The following table lists out the parameters and description of the different attributes of md-progress-circular.

Sr.No Parameter & Description
1

* md-mode

Select from one of the two modes: 'determinate' and 'indeterminate'. If the md-mode value is set as undefined or specified as not 1 of the two (2) valid modes, then .ng-hide will be auto-applied as a style to the component; if not configured, the md-mode = "indeterminate" will be auto injected as an attribute. If value = "" is also specified, however, then md-mode = "determinate" will be autoinjected instead.
2

value

In determinate mode, this number represents the percentage of the circular progress. By default, this is 0.
3

md-diameter

This specifies the diameter of the circular progress. The value may be a percentage (eg '25%') or a pixel-size value (eg '48'). If this attribute is not present, then a default value of '48px' is assumed.

Example

The following example shows the use of the md-progress-circular directive and also the uses of circular progress bars.
