The following constructor is used to create the sketch bar chart

The following is complete snippet taken from the Connext-Graphs Demo web application that demonstrates the sketch bar chart

DefaultOFCGraphDataModel model = new DefaultOFCGraphDataModel(); model.setData(Arrays.asList(data01)); model.setFormat(new DecimalFormat("###0.000")); model.setSeriesType(new OFCBarSketchSeriesType(55, 6, "#d070ac", "#000000", "Test", 10)); controller.add(model);

Project

The project is accessible at https://connext-graphs.dev.java.net/

Example

Add the connext-graph.jar to the WEb_INF/lib folder

Include the taglib in your page

<%@ taglib prefix="m" uri="/connext" %>

Insert the graph tag into your JSP page. In the example the data.txt file contains the controller logic for the graph. If you would a Struts 2 action to provide the controller logic then place it's fully qualified URL in the url property. Example, /contractor/Graph.action if the Graph action provides the logic.

<m:graph id="graph" width="800" height="300" align="middle" bgcolor="#FFFFFF" url="/Graph_example01.action" />

Code the Graph action class. Below is an example of the example01 method

OFCGraphController controller = new OFCGraphController(); controller.getTitle().setText("Example 01"); controller.getTitle().setSize(12); controller.getLabels().setLabels(Arrays.asList(labels)); controller.getYLegend().setText("No. of tasks"); controller.getYLegend().setColor("#8b0000"); controller.getYLegend().setSize(12); controller.getXLegend().setText("Months"); controller.getXLegend().setColor("#8b0000"); controller.getXLegend().setSize(12); controller.getColor().getBgColor().setColor("#FFFFFF"); controller.getColor().getXAxisColor().setColor("#e3e3e3"); controller.getColor().getYAxisColor().setColor("#e3e3e3"); controller.getColor().getXGridColor().setColor("#e3e3e3"); controller.getColor().getYGridColor().setColor("#e3e3e3"); DefaultOFCGraphDataModel model = new DefaultOFCGraphDataModel(); model.setData(Arrays.asList(data01)); model.setFormat(new DecimalFormat("###0.000")); model.setSeriesType(new OFCLineHollowSeriesType(3, "#8b0000", "Test", 10, 6)); controller.add(model); model = new DefaultOFCGraphDataModel(); model.setData(Arrays.asList(data02)); model.setFormat(new DecimalFormat("###0.000")); model.setSeriesType(new OFCLineDotSeriesType(3, "#8b0000", "Test 2", 5, 6)); controller.add(model); model = new DefaultOFCGraphDataModel(); model.setData(Arrays.asList(data03)); model.setFormat(new DecimalFormat("###0.000")); model.setSeriesType(new OFCLineSeriesType(2, "#8b0000", "Example", 4)); controller.add(model); value = controller.render(); return SUCCESS;

Code the graph.jsp page to output the Graph.value property

<%@ include file="include.jsp" %> <s:property value="value" escape="false" />
