<td valign="top" class="text"><p>FusionCharts can effectively be used with ASP to plot dynamic data-driven charts. In this section, we'll show a few basic examples to help you get started.</p>
<p>We'll cover the following examples here:</p>
<ol>
<li>We'll use FusionCharts in ASP with a pre-built Data.xml (which contains data to plot)</li>
<li>We'll then change the above chart into a single page chart using dataXML method.</li>
<li>Finally, we'll use FusionCharts JavaScript class to embed the chart.</li>
</ol>
<p>Let's quickly see each of them. <strong>Before you proceed with the contents in this page, we strictly recommend you to please go through the section "How FusionCharts works?".</strong> </p>

<td valign="top" class="text"><p>This XML is stored as <span class="codeInline">Data.xml</span> in <span class="codeInline">Data </span>Folder under <span class="codeInline">BasicExample</span> folder. It basically contains the data to create a single series chart to show "Monthly Unit Sales". We'll plot this on a Column 3D Chart. Let's see how to do that. </p>
<p>To plot a Chart that consumes this data, you need to include the HTML code to embed a Flash object and then provide the requisite parameters. To make things simpler for you, we've put all this functionality in an ASP function named as <span class="codeInline">renderChartHTML()</span>. This function is contained in <span class="codeInline">Download Package > Code > ASP > Includes > FusionCharts.asp</span> file. So, whenever you need to work with FusionCharts in ASP, just include this file in your page and then you can work with FusionCharts very easily. </p>
<p>Let's see it in example. <span class="codeInline">BasicChart.asp</span> contains the following code to render the chart:</p></td>

<p>However, the good news is that there's a solution to it. This thing happens only when you directly embed the HTML code of the chart. It would NOT happen when you use JavaScript to embed the chart. To see how to embed using JavaScript at code level, please see <span class="codeInline">Creating Your First Chart > JavaScript Embedding</span> Section. </p>
<p>Again, to make things simpler for you, we've provided an ASP function called <span class="codeInline">renderChart() </span>which helps you wrap this JavaScript function in ASP function, so that you don't have to get entangled with JavaScript, Flash and HTML. This function is contained in the previously used <span class="codeInline">FusionCharts.asp</span> file. </p>
<p>Let's now quickly put up a sample to show the use of this function.
