Do I need to build this block?
No. The plugin is delivered with the production version of the block.
If you do wish to modify the code then you can find instructions in the src folder.
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:

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);
`
