Creation

A BBjBarChart object is created through the following BBjWindow methods:

Return Value	Method
BBjBarChart	addBarChart(int ID , int x, int y, int width , int height , boolean showLegend, boolean is3D)
BBjBarChart	addBarChart(int ID, int x, int y, int width, int height, string xLabel, string yLabel, int seriesCount, int categoryCount, boolean showLegend, boolean is3D, boolean isHorizontal)
BBjBarChart	addBarChart(int ID, int x, int y, int width, int height, string xLabel, string yLabel, int seriesCount , int categoryCount , boolean showLegend, boolean is3D , boolean isHorizontal, string flags )

CSS

The visual appearance of BUI controls is defined using CSS (cascading style sheets) rules. Easily change the default colors, border, and other settings by customizing these rules, all without changing any application code. See CSS API for a high-level overview of BUI CSS.

The BBjBarChart is implemented in the browser as an <image> element; all graphing is done on the server. It defines the following style names:

.BBjBarChart

.BBjBarChart.bbj-disabled

Use CSS styles that would work with images, for example:

.BBjBarChart

{

opacity: 0.4;

border-radius: 15px;

border-width: 2px;

box-shadow: 7px 7px 5px rgba(50, 50, 50, 0.5);

}

.BBjBarChart:hover

{

opacity: 1.0;

}

That adds a rounded border and drop shadow to the chart image, and dims it unless the mouse is hovering over it.

Or to show a disabled BBjBarChart grayed out:

.BBjBarChart bbj-disabled

{
