Options and parameters
This extension allows you to provide some parameters to configure how your chart will be rendered.
tagName - DOM element tag name. Default value is 'div';
htmlOptions - HTML options for DOM container.
options - options array, which will be converted to JSON and transfered to jQuery as third parameter when calling function to create chart.
data - data array, which will be converted to JSON and transfered to jQuery as second parameter when calling function to create chart.
excanvas - true/false. Whether to include
excanvas.js or not.
Sometimes you need to include some Flot plugin to make your Chart more interactive.
The following example shows what needs to be added to include, for example,
<?php use bburim\flot\Chart as Chart; use bburim\flot\Plugin as Plugin; echo Chart::widget([ 'data' => [ // As before ], 'options' => [ // As before ], 'htmlOptions' => [ // As before ], // Use `plugins` attribute to load required plugins 'plugins' => [ // Use helper class with constants to specify plugin type Plugin::CANVAS ] ]); ?>
