Introduction to themes

The igPieChart uses the jQuery UI CSS Framework for the purpose of applying styles and themes. By default, the igPieChart uses the IG Theme, part of the jQuery UI theme, provided by Infragistics for use in your application along with some additional chart specific styles. This means that a general jQuery UI theme is insufficient to customize the looks of charts. You will need to provide additional style classes that alter chart specific elements like data series and axes.

You can use ThemeRoller to customize a theme. ThemeRoller is a tool provided by jQuery UI which facilitates the creation of custom themes that are compatible with jQuery UI widgets. Many pre-built themes are available for download and use in your website. The igPieChart control supports the use of ThemeRoller themes.

Detailed information for using themes with NetAdvantage for jQuery library is available in the Styling and Theming topic.

Note: The base theme of NetAdvantage for jQuery is unnecessary for charts and may be omitted on pages that contain only charts.

Themes Summary

Themes summary chart

The following table summarizes the themes available with the igPieChart.



IG Theme

Path: {IG CSS root}/themes/Infragistics/

File: infragistics.theme.css

This theme defines general visual features for all NetAdvantage for jQuery controls. Detailed information for using the IG theme is available in the Styling and Theming NetAdvantage for jQuery topic.

Chart Structure

Path: {IG CSS root}/structure/modules/

File: infragistics.ui.chart.css

This theme defines charts specific visual elements.

Required Cascading Style Sheets (CSSs)

Required CSSs summary

The following CSS resources are necessary for the correct rendering of charts:

  • infragistics.theme.css – Contains the IG Theme
  • infragistics.ui.chart.css – Contains the Chart Structure classes

In the code snippets that follow, it is assumed that the CSS resources are located into Content/ig folder below the web site/application root.

Note: The following blocks provide information on manually including required CSS files; however, we recommended using the Infragistics Loader control to load these files into your page.

Required CSSs code: HTML


<link href="Content/ig/themes/Infragistics/infragistics.theme.css" rel="Stylesheet" />
<link href="Content/ig/structure/modules/infragistics.ui.chart.css" rel="Stylesheet" />

Required CSSs code: ASPX


<link href='<%= Url.Content("~/Content/ig/themes/Infragistics/infragistics.theme.css")%>' rel="stylesheet" type="text/css" />
<link href='<%= Url.Content("~/Content/ig/structure/modules/infragistics.ui.chart.css")%>' rel="stylesheet" type="text/css" />

Chart Styles Reference

Style reference summary

A summary of the igDataChart control’s styles and functions.



.ui-chart-palette-1 to


Sets border and background color for data series 1 to data series N. You can have as many ui-chart-palette classes as needed by your application.


Sets border and background color for chart axes.


Sets all styling options for chart legends.


Sets all styling options for legend item text.


Sets all styling options for legend item icon.


Sets all styling options for chart tooltips.

Note: In all style classes the border-color setting determines the outline of the corresponding element and the background-color setting determines the background or fill color of the element.

Pie Chart Styling Options


The igPieChart control is all about visual content and has a lot of properties and styling options for changing a charts layout and colors. Use CSS to define:

  • colors of data items,
  • colors for legend list items, for text and icons and
  • colors, shades, fonts and other CSS properties for tooltip formatting.

With individual pie chart control options you can define:

  • colors and outline for data items and
  • style for slice labels text.

The following reference table catalogs all options for changing chart element colors and their purpose. When set, pie chart options have precedence over style classes defined in CSS files. These options provide programmatic runtime changes to the rendering of charts.

Modifying the Chart-Specific Visual Elements Using Themes


This procedure explains how to alter the default settings for various visual elements of the igPieChart control by changing the styles in the chart specific infragistics.ui.chart.css file.

Use an existing page with a pie chart, as this example does not provide the procedure for creating a pie chart. In this example, we modify the chart styles by changing the colors of the pie slices.


The following screenshot shows the default view of a sample chart with the default styles along with an example of updated slice colors.

Default slice colors

Updated slice colors


  • To complete the procedure, you need the following:
    • HTML5 web page with an existing igPieChart control.


Step-by-step instructions for creating a custom chart theme. The following is a conceptual overview of the process:

  1. Copy the default chart CSS file
  2. Modify styles for chart visual elements
  3. Change the link from the default chart CSS file to the modified file
  4. Observe the result


Demonstrate how to modify the default IG Chart styles with your preferred settings.



1. Copy the default chart CSS file 

Copy the CSS file with the default chart styles (infragistics.ui.chart.css) from the NetAdvantage for jQuery installation to the themes folder of your web site or application.

For instance, if you have a folder Content/themes in your web site or application where you keep the CSS files used by the application, make a copy of the default chart CSS file mentioned above paste it here, Content/themes/MyChartTheme/ig.ui.chart.custom.css.

2. Modify styles for chart visual elements

Open the copy of the CSS file and make the desired style changes. (Refer to the Chart Styles Reference section for details about the individual igPieChart styles.)


    border-color: rgb(35, 128, 168);
    border-color: rgba(35, 128, 168, .8);
    background-color: rgb(68, 172, 214);

    background-color: rgba(164, 186, 41, .8);
    border-color: #989EA3;
    background-color: #989EA3;
    padding: 10;
    margin: 5px;
    vertical-align: text-bottom;
    vertical-align: baseline;   
    -moz-box-shadow: 5px 5px rgba(0,0,0,0.5);
    -webkit-box-shadow: 5px 5px rgba(0,0,0,0.5);
    box-shadow: 5px 5px rgba(0,0,0,0.5);
3. Change the link from the default chart CSS file to the modified file Update the link to the default chart CSS file to point to the CSS file modified in the previous step.


<link href="/Content/themes/MyChartTheme/ig.ui.chart.custom.css" rel="Stylesheet" type="text/css" />


<link href='<%= Url.Content("~/Content/themes/MyChartTheme/ig.ui.chart.custom.css")%>' rel="stylesheet" type="text/css" />
4. (Optional) Observe the result

To verify that the chart colors and styles have changed, save the web page and open it in your browser.
