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
andd3
) and we wantd1
to use the color#0000FF
,d2
to use#FFFF00
andd3
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 attributetheme
) are used as fallback (#0000FF,second theme color,#008000
); default is no custom colors usedbarThickness
(int): thickness (in pixels) of a bar in bar charts; default is the default Chart.js thicknessbeginYAxisAt0
(bool): make sure the Y axis begins at 0; default isfalse
borderColors
(string): list of custom border colors (separated by comma) to use for datasets. See the description of the attributebackgroundColors
for more details; default is the value of the attributebackgroundColors
class

(bool): fill the area under the line; default isfalse
height
(int): chart height (in pixels); default is the default Chart.js heightindexAxis

,y
; note thaty
is automatically used for horizontal bar charts; default isx
max
(float): maximum value for Y axes; default is no maximum valueopacity
(float): opacity to apply to the lines or bars; it must be between0
and1
; default is0.8
showLine
(bool): show (draw) lines; default istrue
stacked
(bool): enable stacking for line/bar charts; default isfalse
tension
(float): add Bezier curve tension to lines; when set to0
, lines are straight; default is0
theme

,millisecond
; default ishour
type
(string): type of chart; choices arebar
,horizontalbar
,line
,pie
; default isline
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
andd3
) and we wantd1
to use the first Y axis, andd2
andd3
to use the second Y axis, the attribute value must bey,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 axisy
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 processedsb_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 yourfunctions.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);
