Live Charts for Laravel Livewire 3

This package now supports both the Google and ChartJS charting libraries, even both on the same page.

Live?

Live as in the charts will auto refresh at a specified poll interval using the Livewire wire:poll attribute.

Note that the component is only drawn the first time and thereafter only the data is updated on every poll, so the data transferred for polling is significantly less and the chart is just updated, not recreated every time.

Coffee? ☕

One of my favorite escapes from coding and business is taking my wife for a coffee.
(Which is pretty cheap in sunny South Africa).

If you use this package please think about how much time and effort you have saved and buy us a coffee. ☕

Requirements

• Laravel 9+
• Livewire 3+

Installation

Configuration

A number of defaults can be set if you publish the config file:

The values in the config file should be pretty self-explanotory.

Obtaining the Data

The package uses a cached query builder (or any external data source) to fetch the data. Actually only the query, bindings and connection is cached because we can not cache the builder class(es) between requests.

You have to start by prepairing a builder that will fetch your data every time the data needs to be refreshed.

Something like this:

This builder will give you nice random data for testing:

External Data Sources:

To use an external data source, such as a third party API, just extend one of the chart components and add a getExternalData() method to your component.

See EXTERNAL for more details.

Configure the Chart

• library selects which charting library to use - google/chartjs
• title should be obvious - leave empty for no title inside the chart
• builder is the builder instance (without ->get()!)
• poll is the poll interval in seconds - 0 means no polling/refresh it will just draw the chart once
• width and height can be anything that HTML will understand - px, %, em, etc.
• colors provide a color pallette as an array of colors
• is3D (true/false) make some charts 3D
• pieHole (0.0 to 1.0) controls the relative size of the pie hole for donut charts
• jsTypes is an array of series types for mixed series ChartJS charts

Most of the options have sensible defaults from the config file and can be left out.

Blade

Available charts

• Pie
• Donut
• Bar
• Column
• Line
• Area
• Multi/Mixed Bar, Line, Area (ChartJS only)
• Candlestick (Google only)

Just replace pie in the blade example above with donut, bar, column, etc.

Note that for a candlestick chart the builder should return 5 columns.

Colors

You can specify the color pallete for the chart by adding a colors array to the options.
Any color that will work in HTML will work eg:

Mixed/Multi chart types

For a ChartJS chart with mixed bar/line/area data series just add a jsTypes array with the types.

Other Library Options

Any other options can be passed to the chart library by simply adding an options array to the chart options:

This package was originally an extension of the excellent Helvetitec/lagoon-charts Google charts package by Helvetitec.
Except these ones are "live" :-)
