<h1>Flot Examples</h1>
<div id="placeholder" style="width:600px;height:300px;"></div>
<p>Example of loading data dynamically with AJAX. Percentage change in GDP (source: <a href="http://epp.eurostat.ec.europa.eu/tgm/table.do?tab=table&init=1&plugin=1&language=en&pcode=tsieb020">Eurostat</a>). Click the buttons below.</p>
<p>The data is fetched over HTTP, in this case directly from text
files. Usually the URL would point to some web server handler
(e.g. a PHP page or Java/.NET/Python/Ruby on Rails handler) that
extracts it from a database and serializes it to JSON.</p>
<p>
<input type="button" value="First dataset"> -
<a href="data-eu-gdp-growth.json">data</a> -
<span></span>
</p>
<p>
<input type="button" value="Second dataset"> -
<a href="data-japan-gdp-growth.json">data</a> -
<span></span>
</p>
<p>
<input type="button" value="Third dataset"> -
<a href="data-usa-gdp-growth.json">data</a> -
<span></span>
</p>
<script id="source" language="javascript" type="text/javascript">
$(function () {
var options = { lines: { show: true }, points: { show: true } };
var data = [];

var alreadyFetched = {};
$("input[type=button]").click(function () {
var button = $(this);
// find the URL in the link right next to us
var dataurl = button.siblings('a').attr('href');
// then fetch the data with jQuery
function onDataReceived(series) {
// extract the first coordinate pair so you can see that
// data is now an ordinary Javascript object
var firstcoordinate = '(' + series.data[0][0] + ', ' + series.data[0][1] + ')';
button.siblings('span').text('Fetched ' + series.label + ', first point: ' + firstcoordinate);
// let's add it to our current data
if (!alreadyFetched[series.label]) {
alreadyFetched[series.label] = true;
data.push(series);
}
// and plot all we got
