Bar Chart Metrics
For a bar chart metric, just create a metric class like you normally would for a Partition
metric. All the available methods in a Partition
metric are also available for BarChartMetric
! Instead of extending Partition
you would just need to extend BarChartMetric
like so:
use Insenseanalytics\NovaBarMetrics\BarChartMetric; class BrandsPerCategory extends BarChartMetric { public function calculate(Request $request) { return $this->count($request, BrandCategory::class, 'category_name'); } }
You can also use the suffix
, prefix
, dollars
and euros
methods like in a TrendMetric
in Laravel Nova. Besides this, we also have a precision
method to set the precision of the avg
metric shown in the top right corner of the bar chart.
Frequency Distributions for Bar Chart Metrics and Partition Metrics
To create a frequency distributions chart, either extend the BarChartMetric
class or extend the Partition
class and use the trait HasFrequencyDistributions
. You can use the distributions
helper method to create the frequency distribution chart like so:
Example for BarChartMetric
use Insenseanalytics\NovaBarMetrics\BarChartMetric; class BrandFacebookFollowers extends BarChartMetric { public function calculate(Request $request) { return $this->distributions($request, Brand::class, 'facebook_followers', 100000); } }
In the example above, 100000 is the step size
to use for the ranges in the frequency distribution and facebook_followers is the column to distribute
by ranges.
Instead of providing the step size
, you may provide the max number of steps instead using the distributionsWithSteps
method and the package would automatically calculate the step size like so:
use Insenseanalytics\NovaBarMetrics\BarChartMetric; class BrandFacebookFollowers extends BarChartMetric { public function calculate(Request $request) { return $this->distributionsWithSteps($request, Brand::class, 'facebook_followers', 15); } }
For friendly formatted ranges (K for thousands, M for millions, B for billions), you can use the withFormattedRangeLabels
method like so:
public function calculate(Request $request) { return $this->distributions($request, Brand::class, 'facebook_followers', 100000) ->withFormattedRangeLabels(); }
Example for Partition Metric
use Laravel\Nova\Metrics\Partition; use Insenseanalytics\NovaBarMetrics\HasFrequencyDistributions; class BrandFacebookFollowers extends Partition { use HasFrequencyDistributions; public function calculate(Request $request) { return $this->distributions($request, Brand::class, 'facebook_followers', 100000); } }
Requirements & Dependencies
There are no PHP dependencies except the Laravel Nova package. On the frontend JS, this package uses vue
, chartist
, chartist-plugin-tooltips
and laravel-nova
, all of which are also used by Nova itself.
Installation
You can install this tool into a Laravel app that uses Nova via composer:
composer require insenseanalytics/nova-bar-metrics
Next, if you do not have package discovery enabled, you need to register the provider in the config/app.php
file.
'providers' => [ ..., Insenseanalytics\NovaBarMetrics\NovaBarMetricsServiceProvider::class, ]
Usage
You can use the console command php artisan nova:barmetric <classname>
to create new BarMetric classes
