options

Advanced options specified as JSON. Checkout the Chart.js documentation for the available configuration options. In addition to the options that can be defined in the standard ChartJS library, the following options can be used in this macro:

"opacity": 0.8Makes it possible to define an opacity level for all the background colors.
"width": "400px"Overrides the chart container width that gets computed automatically.
"height": "400px"Overrides the chart's container height that gets computed automatically. If used in combination with the width option, the option maintainAspectRatio has to be set to false for both options to be taken into account.
"backgroundColors": ["#ff16e8", "#0018f4","#065d00"]For charts of type line, bar, horizontalBar or radar, this option makes it possible to define one background color per data set or one per value, withtout the need to define the colors for each data set individually.
"afterValue": "%"Suffixes the data label values with the given sign or string (e.g. "%", "€", etc.).
"options.scales.xAxes[0].ticks.afterValue: "%"(Same for yAxes) suffixes the data labels with the given string.
"skipZeros": trueInstructs the macro to not display values equalling to 0.
"tooltips": {"maxCharactersPerLine": 50}In case of long data labels, this option makes it possible to display the full data label in the tooltips, on several lines.
"tooltips": {"position": {"left": 0.5, "bottom": 0.2}}		Allows to position the tooltips at a specific position of the canvas computed as the canvas' width or height multiplied by the given value (of "left" or "bottom"). If no value is provided, the "average" positioner is used.
