**SVG Charts for PHP**

This project aims to be a complete solution for creating SVG charts in PHP. It is especially useful when charts need to be generated on the back-end to be included in emails and PDFs.

[![examples](app/example.png)](app/example.png)

Available Chart Types
---------------------

[](#available-chart-types)

### Bar Chart

[](#bar-chart)

- Can be stacked
- Can have a right axis with the `nbYkeys2` option

### Line Chart

[](#line-chart)

- Can be curved or straight
- Can include a time scale
- Can display objectives
- Can display events
- Can display a trend line
- Can have a right axis with the `nbYkeys2` option

### Area Chart

[](#area-chart)

Same as Line chart, just set the option `fillOpacity` to a value greater than 0 (i.e. 0.3);

### Pie Chart

[](#pie-chart)

- Can be converted to a polar pie chart by adding a coefficient (see example below)

### Bubble Chart

[](#bubble-chart)

- Can include a time scale

### Radar Chart

[](#radar-chart)

- Can be stacked

#### Other options

[](#other-options)

- `numLines` number of horizontal grid lines in the chart
- `responsive` set to `false` to disable responsive mode
- `showYAxis` set to `false` will hide the Y axis
- `unitY1` / `unitY2` units for the Y axes
- `labelAngle` to rotate the labels of the X axis

Installation
------------

[](#installation)

```
composer require pierresh\simca
```

How to use
----------

[](#how-to-use)

Example to generate a SVG chart:

```
use Pierresh\Simca\Charts\BarChart;

$chart = (new BarChart(600, 400))
	->setSeries([[10, 45, 30, 25], [15, 20, 15, 25], [5, 2, 10, 15]])
	->setLabels(['A', 'B', 'C', 'D'])
	->setColors(['#2dd55b', '#ffc409', '#0054e9'])
	->setOptions([
		'stacked' => true,
		'nbYkeys2' => 1,
	])
	->render();
```

```
use Pierresh\Simca\Charts\LineChart;

$chart = (new LineChart(600, 400))
	->setSeries([[10, 45, 30, 25], [15, 20, 15, 25]])
	->setLabels(['2024-06-01 08:00', '2024-06-01 09:00', '2024-06-01 13:00', '2024-06-01 13:30'])
	->addObjectiveY1(20)
	->addEvent('2024-06-01 10:00')
	->addEvent('2024-06-01 12:15')
	->showTrend()
	->setOptions([
		'timeChart' => true,
		'unitY1' => 'T',
		'nbYkeys2' => 1,
	])
	->render();
```

```
use Pierresh\Simca\Charts\PieChart;

// The secondary value is an optional coefficient for polar pie chart
$chart = (new PieChart(400, 400))->setSeries([[14, 0.5], [3, 0.9], [5, 0.8], [5, 1], [5, 0.9]])->render();
```

```
use Pierresh\Simca\Charts\BubbleChart;

$chart = (new BubbleChart(600, 400))
	->setSeries([['2024-06-01 08:00', 40, 30], ['2024-06-01 09:00', 20, 15], ['2024-06-01 12:00', 30, 25]])
	->setOptions([
		'timeChart' => true,
	])
	->render();
```

```
use Pierresh\Simca\Charts\RadarChart;

$chart = (new RadarChart(600, 400))
	->setSeries([[65, 59, 90, 81, 56, 55, 40], [38, 48, 40, 19, 96, 27, 100]])
	->setLabels(['Eating', 'Drinking', 'Sleeping', 'Designing', 'Coding', 'Cycling', 'Running'])
	->setOptions([
		'fillOpacity' => 0.3,
	])
	->render();
```

Alternatively, you can replace `render()` with `renderBase64()` to get a base64 encoded SVG image.
