Rendering Charts in Blade

After you passed $chart variable, into Blade, you can render it, by doing three actions:

Action 1. Render HTML.

Wherever in your Blade, call this:

It will generate something like this:

Action 2. Render JavaScript Library

Package is using Chart.js library, so we need to initialize it somewhere in scripts section:

It will generate something like this:

Action 3. Render JavaScript of Specific Chart

Using Multiple Charts

You can show multiple charts on the same page, initialize them separately.

Controller:
