NetCharts® Server: Getting a Dynamic Chart Example

This example shows how to utilize the NetCharts Server Java Toolkit to add an interactive chart to a web page. The example uses the netcharts.server.api.NSWebToolkit class to add a chart with popup labels onto the page. See the Source Code.

Note: This is a static image only - no interactivity.
NetCharts Server JSP Example of Dynamic Chart

Source Code

<%@ page import="netcharts.server.api.NSWebToolKit" %>
<%@ page import="java.util.Hashtable" %>

Create an instance of the NSWebToolKit class.
<%
NSWebToolKit toolKit = new NSWebToolKit("localhost", 8001, "Examples/Suppliers");
// If the JSP page is running with NetCharts Server, use this constructor instead.
// NSToolKit toolKit = new NSToolKit("Examples/Suppliers");

// Create the Hashtable to hold the chart request variables.
// (NOTE: If the Hashtable == null, type=PNG is the default)
Hashtable variables = new Hashtable();
variables.put("type","PNG");
%>

The function getRolloverJavaScript is used to retrieve the JavaScript used to
retrieve the JavaScript used for client-side interactivity.
<%=toolKit.getRolloverJavaScript()%>

The function getChartAsImageAndMap is used to create the image tag and
imagemap and add it to the page.
<%=toolKit.getChartAsImageAndMap("basicbar.cdx", variables, request, false)%>

Additional calls to the function getChartAsImageAndMap will add more dynamic
charts to the page.
