Строим график Flot с данными из базы Sqlite
Flot — это JavaScript библиотека, основанная на библиотеке jQuery, с простым использованием, привлекательным внешним видом и интерактивными функциями.
Однажды мне понадобилось построить график по данным из базы Sqlite, но к сожалению в интернете не было не чего внятного, как оказалось все довольно легко!
1. Делаем выборку из базы данных adatum.sqlite.
<?php
$db = new PDO('sqlite:./adatum.sqlite');
$st = $db->query('SELECT id,records FROM statement');
$results = $st->fetchAll(); foreach ($results as $row)
{$dataset[] = array($row['id'],$row['records']);}
?>
2. Подставляем в javascript полученный массив в формате json.
$(function () {
var sqlite = <?php echo json_encode($dataset); ?>;
3. Ну и на по следок весь код с построением различных типов графиков.
<br><h1>График на данных из базы данных Sqlite</h1> <br>
<div class="sqlite-chart" style="height: 230px; width:100%;"></div>
<br><h1>Simple chart</h1> <br>
<div class="simple-chart" style="height: 230px; width:100%;"></div>
<br><h1>Donut simple chart</h1> <br>
<div class="lines-chart" style="height: 230px;width:100%;"></div>
<br><h1>Pie simple chart</h1> <br>
<div class="order-bars-chart" style="height: 230px;width:100%;"></div>
<br><h1>Ordered bars chart </h1><br>
<div class="simple-donut" style="height: 230px;width:100%;"></div>
<br><h1>Stacked bars chart </h1><br>
<div class="stacked-bars-chart" style="height: 230px;width:100%;"></div>
<br><h1>Lines chart without points</h1><br>
<div class="simple-pie" style="height: 230px;width:100%;"></div>
<br><h1>Horizontal bars chart</h1> <br>
<div class="horizontal-bars-chart" style="height: 230px;width:100%;"></div>
<br><h1>Auto update chart </h1> <br>
<div class="auto-update-chart" style="height: 230px;width:100%;"></div>
</div>
<?php
$st = (new PDO('sqlite:./adatum.sqlite'))->query('SELECT id,records FROM statement'); foreach (($st->fetchAll()) as $row) {$dataset[] = array($row['id'],$row['records']);}
?>
