Introduction to the FusionCharts JSP Wrapper
FusionCharts JSP Wrapper can be downloaded from here.
FusionCharts Suite XT includes the FusionCharts JSP wrapper that lets you create interactive, data-driven charts without writing any JavaScript code.
JavaScript and HTML code is used to generate charts in the browsers. The server-side JSP wrapper generates the required JavaScript and HTML code as a string, which is then used to render charts on a browser page.
In this section, you will be shown how you can create a simple chart using the FusionCharts server-side JSP wrapper.
We will create a simple column 2D chart that plots the monthly revenue for the last year at Harry’s SuperMart. The data for the chart is shown in the table below:
Month | Revenue (In USD) |
---|---|
Jan |
420000 |
Feb |
810000 |
Mar |
720000 |
Apr |
550000 |
May |
910000 |
Jun |
510000 |
Jul |
680000 |
Aug |
620000 |
Sep |
610000 |
Oct |
490000 |
Nov |
900000 |
Dec |
730000 |
The rendered column 2D chart will look like this:
The data structure to render this chart is explained below:
Step 1:
Include the fusioncharts.js
file, as shown in the code snippet below.
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<title>Loading Data from a Static JSON String - fusioncharts.com</title>
<script src="fusioncharts.js"></script>
</head>
<body>
<div id="chart-container"></div>
This file is needed to render the chart. Ensure that the path to this JS file is correct. Otherwise, it may lead to JavaScript errors. Download FusionCharts from here.
Step 2:
Include the FusionCharts.java
file as a package in your project.
Step 3:
Include the package in the file where you want to show FusionCharts.
Step 4:
Create a chart object using the FusionCharts JAVA class constructor.
Syntax for the constructor:
FusionCharts("type of chart", "unique chart id", "width of chart", "height of chart", "div id to render the chart", "data format", "data source")
<%
FusionCharts column2dChart = new FusionCharts(
// type of chart
"column2D",
// unique chart ID
"myFirstChart",
// width and height of the chart
"500","300",
// div ID of the chart container
"chart-container",
// data format
"json",
// data source
"{
\"chart\": {
\"caption\": \"Monthly revenue for last year\",
\"subCaption\": \"Harry's SuperMart\",
\"xAxisName\": \"Month\",
\"yAxisName\": \"Revenues (In USD)\",
\"numberPrefix\": \"$\",
\"theme\": \"zune\"
},
\"data\": [{
\"label\": \"Jan\",
\"value\": \"420000\"
}, {
\"label\": \"Feb\",
\"value\": \"810000\"
}, {
\"label\": \"Mar\",
\"value\": \"720000\"
}, {
\"label\": \"Apr\",
\"value\": \"550000\"
}, {
\"label\": \"May\",
\"value\": \"910000\"
}, {
\"label\": \"Jun\",
\"value\": \"510000\"
}, {
\"label\": \"Jul\",
\"value\": \"680000\"
}, {
\"label\": \"Aug\",
\"value\": \"620000\"
}, {
\"label\": \"Sep\",
\"value\": \"610000\"
}, {
\"label\": \"Oct\",
\"value\": \"490000\"
}, {
\"label\": \"Nov\",
\"value\": \"900000\"
}, {
\"label\": \"Dec\",
\"value\": \"730000\"
}]
}"
);
%>
Note: Instead of coping the code from the code viewer, use copy to clipboard button to copy the code. The reason we suggest this because in a code viewer, break lines(which is a complete string line) has been used to display the proper method to set the chart cosmetics and how the datasource can be passed as a parameter.
Step 5:
Render the chart.
