      <p>In this section, we'll show you how to use FusionCharts with JSP to plot 
        data collected in forms. </p>
      <p>We'll build a simple restaurant sales example, where the user will enter the items sold by a restaurant in a given week. This data will be submitted in a form to the server. We'll acquire this data and plot in on a chart. For the sake of simplicity, we wouldn't do any processing on this data. However, your real life applications might process data before presenting it on the chart. </p>
    <p><strong>Before you go further with this page, we recommend you to please see the previous section &quot;Basic Examples&quot; as we start off from concepts explained in that page. </strong></p>
    <p class="highlightBlock">The code examples contained in this 
        page are present in<span class="codeInline"> Download Package &gt; Code 
    &gt; JSP</span> &gt; <span class="codeInline">FormBased</span> folder. </p>
    <p><span class="header">Building the Form </span></p>
    <p>The form is contained in <span class="codeInline">Default.jsp</span> and looks as under: </p>
    <p><img src="Images/Code_Form.gif" class="imageBorder" /></p>
    <p>It's a very simple form which submits to <span class="codeInline">Chart.jsp</span>. As such, we wouldn't go into the code of this form. You can directly open the source from download and see it. </p>
    <p><span class="header">Requesting the data and Creating the Chart </span></p>
    <p>The work of requesting the data from submitted form and creating the chart is done in <span class="codeInline">Chart.jsp</span>, present in the same folder. It contains the following code: </p>
    <p class="codeBlock">&lt;HTML&gt;<br />

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;You need to include the following JS file, if you intend to embed the chart using JavaScript.<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Embedding using JavaScripts avoids the &quot;Click to Activate...&quot; issue in Internet ExplorerWhen you make your own charts, make sure that the path &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;to this JS file is correct. Else, you would get JavaScript errors.<br />

    <ul>
      <li>Including <span class="codeInline">FusionCharts.js</span> in this page. </li>
      <li>Requesting data from the submitted form and storing it in local variables</li>
      <li>Creating an XML data document using string concatenation and storing it in <span class="codeInline">strXML</span> variable </li>
      <li>Rendering a Pie 3D chart by including FusionChartsRenderer.jsp and passing <span class="codeInline">strXML</span> as parameter.</li>
    </ul>
    <p>When you finally run the code, you'll see a chart as under:</p>
    <p> <img src="Images/Code_FormChart.jpg" width="468" height="268" class="imageBorder" /></p></td>
