ASP .NET Core MVC Documentation

Getting Started

jqxBarGauge displays an indicator within a range of values. Gauges can be used in a table or matrix to show the relative value of a field in a range of values in the data region.

Every UI widget from jQWidgets toolkit needs its JavaScript files to be included in order to work properly.

jqxBarGauge widget requires the following files:

• jqxbargauge.js

The next step is to create html element within the body of the html document and add the initialization attributes.

<script src="../jqwidgets/jqxbargauge.js"></script>
@{
	ViewData["Title"] = "ASP .NET MVC Bar Gauge Example";
	List<string> ranges = new List<string>()
	{
		'{ start-value: 0, end-value: 200, color: \"#000000\", opacity: 0.5 }',
		'{ start-value: 200, end-value: 250, color: \"#000000\", opacity: 0.3 }',
		'{ start-value: 250, end-value: 300, color: \"#000000\", opacity: 0.1 }'
	};
	List<double> barGaugeValues = new List<double>()
	{
		102, 115, 130, 137
	};
	string labels = '{ connectorColor: 'green', connectorWidth: 1}';
	string labels = '{ connectorColor: 'green', connectorWidth: 1}';
	string title = '{text: 'Ranking'}';
	string tooltip = '{formatFunction: function(value, index) { return value + ' $';}, visible: true, precision: 0 }';
	string rendered = '{rendered: function() {}}';
	string formatFunction = '{formatFunction: function(value, index, color) { return "red";}}';
}
<jqx-bar-gauge animation-duration="500" values="barGaugeValues" width="600" height="600" max="150" ranges="ranges"></jqx-bar-gauge>

To call a function(method), you need to pass the method name and parameters(if any) in the jqxBarGauge’s instance.

                                     
<script src="../jqwidgets/jqxbargauge.js"></script>
@{
	ViewData["Title"] = "ASP .NET MVC Bar Gauge Example";
	List<string> ranges = new List<string>()
	{
		'{ start-value: 0, end-value: 200, color: \"#000000\", opacity: 0.5 }',
		'{ start-value: 200, end-value: 250, color: \"#000000\", opacity: 0.3 }',
		'{ start-value: 250, end-value: 300, color: \"#000000\", opacity: 0.1 }'
	};
	List<double> barGaugeValues = new List<double>()
	{
		102, 115, 130, 137
	};
	string labels = '{ connectorColor: 'green', connectorWidth: 1}';
	string labels = '{ connectorColor: 'green', connectorWidth: 1}';
	string title = '{text: 'Ranking'}';
	string tooltip = '{formatFunction: function(value, index) { return value + ' $';}, visible: true, precision: 0 }';
	string rendered = '{rendered: function() {}}';
	string formatFunction = '{formatFunction: function(value, index, color) { return "red";}}';
}
<jqx-bar-gauge values="barGaugeValues" width="600" height="600" max="150" ranges="ranges" instance="getInstance()"></jqx-bar-gauge>
							
@section scripts {								
<script type="text/javascript">									
	function getInstance(instance) {									
		instance["val"]([112, 125, 150, 137]);									
	}									
</script>									
}

    

To bind to an event of a UI widget, you can use on-event-type syntax. The example code below demonstrates how to bind to an event.

                                     
<script src="../jqwidgets/jqxbargauge.js"></script>
@{
	ViewData["Title"] = "ASP .NET MVC Bar Gauge Example";
	List<string> ranges = new List<string>()
	{
		'{ start-value: 0, end-value: 200, color: \"#000000\", opacity: 0.5 }',
		'{ start-value: 200, end-value: 250, color: \"#000000\", opacity: 0.3 }',
		'{ start-value: 250, end-value: 300, color: \"#000000\", opacity: 0.1 }'
	};
	List<double> barGaugeValues = new List<double>()
	{
		102, 115, 130, 137
	};
	string labels = '{ connectorColor: 'green', connectorWidth: 1}';
	string labels = '{ connectorColor: 'green', connectorWidth: 1}';
	string title = '{text: 'Ranking'}';
	string tooltip = '{formatFunction: function(value, index) { return value + ' $';}, visible: true, precision: 0 }';
	string rendered = '{rendered: function() {}}';
	string formatFunction = '{formatFunction: function(value, index, color) { return "red";}}';
}
<jqx-bar-gauge on-draw-end="eventHandler()"></jqx-bar-gauge>
							
@section scripts {								
<script type="text/javascript">									
	function eventHandler(event) {									
	}									
</script>									
}
