public TestChartFactory()

Method Detail

setUp

protected void setUp()

Automatically called by JUnit before execution of each test case

Overrides:

setUp in class junit.framework.TestCase

testCanReadFormat

public void testCanReadFormat()

A unit test to verify ChartFactory.canReadFormat returns the correct value with several parameters

testCanWriteFormat

public void testCanWriteFormat()

A unit test to verify ChartFactory.canWriteFormat returns the correct value with several parameters

testBar01

public void testBar01()

Create a simple bar chart with 18 bars using default style and metrics. This chart is based on one published at http://www.scotland.gov.uk/library/sas/sa09-22.htm.

testBar02

public void testBar02()

Create a bar chart, replacing the default style with different colors, enabling the chart border, and adding an ImageLayer to place a logo under the first bar. This chart is based on data published by Netcraft (http://www.netcraft.com).

testBar03

public void testBar03()

Create a bar chart with custom style and metrics, using a bar color association key and a TextLayer to add a source reference in the background of the chart image. This chart is based on data published by Netcraft (http://www.netcraft.com).

testBar04

public void testBar04()

Create a bar chart with a gradient background, using diagonal bar labels and a transparent gif image defined by a URI to display a tornado graphic in the chart. This image also contains two text layers - one in the background of the chart and one at the bottom. This chart is based on data published by NASA at http://thunder.msfc.nasa.gov/bookshelf/docs/white_paper_driscoll.html

testBar05

public void testBar05()

Create a bar chart with custom style, horizontal bar labels, a transparent PNG ImageLayer, and a TextLayer. The data for this chart was published by Netcraft (http://www.netcraft.com).

testBar06

public void testBar06()

Create a bar chart with GradientPaint bar colors, a TextLayer, and a bar color association key (despite the relatively few bars). Data for this chart is published by TechRepublic.

testBar07

testBar08

public void testBar08()

Create a custom-styled chart that is intended to stress title and label width limits as well as the overall bar limit ChartStyle.MAX_BARS. It also demonstrates a bug that although only ChartStyle.MAX_BARS bars will be displayed, all data points are taken into consideration when preparing the pixel interval.
