Are there shortcodes available?

Charts can be embedded with the shortcode chartjs. The general syntax is as follows:

[chartjs attribute="attribute value"]CSV content[/chartjs]

Several attributes can be added at the same time. Example:

[chartjs attribute1="attribute1 value" attribute2="attribute2 value"]CSV content[/chartjs]

Here’s the list of supported attributes:

  • backgroundColors (string): list of custom background colors (separated by comma) to use for datasets. For example, if there are 3 datasets (d1, d2 and d3) and we want d1 to use the color #0000FF, d2 to use #FFFF00 and d3 to use #008000, the value of the attribute must be #0000FF,#FFFF00,#008000. If some colors are missing (ex.: #0000FF,,#008000), default colors from the theme (set with the attribute theme) are used as fallback (#0000FF,second theme color,#008000); default is no custom colors used
  • barThickness (int): thickness (in pixels) of a bar in bar charts; default is the default Chart.js thickness
  • beginYAxisAt0 (bool): make sure the Y axis begins at 0; default is false
  • borderColors (string): list of custom border colors (separated by comma) to use for datasets. See the description of the attribute backgroundColors for more details; default is the value of the attribute backgroundColors
  • class (string): class or classes to be added to the chart container; default is an empty string
  • fill (bool): fill the area under the line; default is false
  • height (int): chart height (in pixels); default is the default Chart.js height
  • indexAxis (string): axis to use as index; choices are x, y; note that y is automatically used for horizontal bar charts; default is x
  • max (float): maximum value for Y axes; default is no maximum value
  • opacity (float): opacity to apply to the lines or bars; it must be between 0 and 1; default is 0.8
  • showLine (bool): show (draw) lines; default is true
  • stacked (bool): enable stacking for line/bar charts; default is false
  • tension (float): add Bezier curve tension to lines; when set to 0, lines are straight; default is 0
  • theme (string): theme used for the chart colors; choices are Chart, Gutenberg, Rainbow, Tertiary, Visualizer, WordPress; default is Chart
  • time (bool): add support for time line on the X axis; default is false
  • timeUnit (string): time unit to use if time line is enabled; choices are year, quarter, month, week, day, hour, minute, second, millisecond; default is hour
  • type (string): type of chart; choices are bar, horizontalbar, line, pie; default is line
  • yAxes (string): list of Y axes to which the datasets are bound. It allows to enable multi-axis charts. For example, if there are 3 datasets (d1, d2 and d3) and we want d1 to use the first Y axis, and d2 and d3 to use the second Y axis, the attribute value must be y,y1,y1; default is an empty string, so multi-axis feature is disabled and all datasets are automatically bound to the first (and only) Y axis y

Here’s a fully functional example:

[chartjs backgroundColors="#008000" fill="true" opacity="0.35" tension="0.2" theme="Visualizer" time="true" timeUnit="month" yAxes="y,y1"]Year,Sales,Expenses
2020-08,5421.32,1151.21
2021-02,4823.99,887.23
2021-03,4945.32,958.00
2021-10,7086.65,1854.35
2022-05,7385.21,2009.01
[/chartjs]

Here’s the result:

Are there hooks available for developers?

The following filter hooks are available:

  • sb_chart_block_content: filter allowing to manipulate the content before it’s processed
  • sb_chart_block_options: filter allowing to add custom Chart.js options

For example, to customize the legend, use the sb_chart_block_options filter in your functions.php theme file as follows:

`php

function customize_legend($options, $atts, $series) {
$custom_options = to_array($options);

$custom_options['plugins']['legend']['labels']['font']['size'] = 16;
$custom_options['plugins']['legend']['labels']['color'] = '#0000FF';

return json_decode(json_encode($custom_options));

}
add_filter(‘sb_chart_block_options’, ‘customize_legend’, 10, 3);

function to_array($data) {
$array = [];

if (is_array($data) || is_object($data)) {
    foreach ($data as $key => $value) {
        $array[$key] = (is_array($value) || is_object($value)) ? to_array($value) : $value;
    }
} else {
    $array[] = $data;
}

return $array;

}
`

Here’s another way (without array conversion):

`php

function customize_legend($options, $atts, $series) {
if (!isset($options->plugins)) $options->plugins = new stdClass();
if (!isset($options->plugins->legend)) $options->plugins->legend = new stdClass();
if (!isset($options->plugins->legend->labels)) $options->plugins->legend->labels = new stdClass();
if (!isset($options->plugins->legend->labels->font)) $options->plugins->legend->labels->font = new stdClass();

$options->plugins->legend->labels->font->size = 16;
$options->plugins->legend->labels->color = '#0000FF';

return $options;

}
add_filter(‘sb_chart_block_options’, ‘customize_legend’, 10, 3);
`
