SVGGraph general settings

« Return to SVGGraph page

Many of the ways that things are displayed on the graphs may be changed by passing in an array of settings to the SVGGraph constructor:

<?php
require_once 'SVGGraph/autoloader.php';

$width = 500;
$height = 400;

$settings = array(
  'back_colour' => 'white',
  'graph_title' => 'Start of Fibonacci series'
);

$graph = new Goat1000\SVGGraph\SVGGraph($width, $height, $settings);

$graph->values(0, 1, 1, 2, 3, 5, 8, 13, 21);
$graph->render('BarGraph');

A list of options that are valid for all types of graph and their default values are shown below. Sizes are always in pixels - you should not append 'px' or any other CSS units.

Because the settings are stored in a standard PHP array, numbers, boolean values (true and false) and NULL values should be used without surrounding quotes. All other values (except arrays) are strings, and should be quoted with either single or double quotes.

A full list of all available options, which can be filtered by graph type or tag, is available on the options index page.

The table below lists all options tagged as global from the index.

For details of the options specific to each type of graph, please visit the relevant page:

• Bar graphs
• 3D bar graphs
• Horizontal bar graphs
• Line graphs
• Scatter graphs
• Radar graphs
• Pie graphs

For more examples and for complete explanations of some of these options, take a look at the background image page, the axis and grid dimensions page, the titles and axis labels page and the legends page.
