The above example shows you how to create LineChart using ChartJs package. In this example, for purpose of chart demonstration only, we do use mock-up data from array. As you can see, the KoolReport's widget in general support dataSource could be DataStore, Process, DataSource or even simple array.
This example shows how to build line charts with different point style and point style of legend using the usePointStyle and pointStyle properties.
For example:
...
'columns' => array(
"month",
"My First dataset" => array(
...
"pointStyle" => 'rectRot'
)
),
"options" => array(
...
"legend" => array(
'labels' => array(
"usePointStyle" => false
)
),
)
<div id="report_render" style="display: flex;flex-direction: row;flex-wrap: wrap;justify-content: center;">
<?php
function randomScalingFactor()
{
return mt_rand(-100, 100);
}
$options = [
["text" => "Nomal Legend", 'usePointStyle' => false, "rgb" => "rgb(255, 99, 132)", 'rgba' => 'rgba(255, 99, 132, 0.5)'],
["text" => "Point Style Legend", 'usePointStyle' => true, "rgb" => "rgb(54, 162, 235)", 'rgba' => 'rgba(54, 162, 235, 0.5)'],
];
$data = [
['month' => 'January', 'My First dataset' => randomScalingFactor()],
['month' => 'February', 'My First dataset' => randomScalingFactor()],
['month' => 'March', 'My First dataset' => randomScalingFactor()],
['month' => 'April', 'My First dataset' => randomScalingFactor()],
['month' => 'May', 'My First dataset' => randomScalingFactor()],
['month' => 'June', 'My First dataset' => randomScalingFactor()],
['month' => 'July', 'My First dataset' => randomScalingFactor()]
];
for ($i = 0; $i < count($options); $i++) {
?>
<div style="width:500px;margin-left: 40px;margin-right: 40px;">
<?php
\koolreport\chartjs\LineChart::create(array(
'dataSource' => $data,
'columns' => array(
"month",
"My First dataset" => array(
"backgroundColor" => $options[$i]['rgba'],
"borderColor" => $options[$i]['rgb'],
"borderWidth" => 1,
"fill" => true,
"pointRadius" => 5,
"pointBorderColor" => 'rgb(0, 0, 0)',
"pointStyle" => 'rectRot'
)
),
"options" => array(
"responsive" => true,
"title" => array(
"display" => true,
"text" => $options[$i]['text'],
),
"legend" => array(
'labels' => array(

)

)
)
