The configuration is used to change how the chart behaves. There are properties to control styling, fonts, the legend, etc.
method _animation : animation Js_of_ocaml.Js.t Js_of_ocaml.Js.propChart.js animates charts out of the box. A number of options are provided to configure how the animation looks and how long it takes.
method layout : layout Js_of_ocaml.Js.t Js_of_ocaml.Js.propLayout configurations.
method legend : legend Js_of_ocaml.Js.t Js_of_ocaml.Js.propThe chart legend displays data about the datasets that are appearing on the chart.
method title : title Js_of_ocaml.Js.t Js_of_ocaml.Js.propThe chart title defines text to draw at the top of the chart.
method hover : hover Js_of_ocaml.Js.t Js_of_ocaml.Js.propmethod tooltips : tooltip Js_of_ocaml.Js.t Js_of_ocaml.Js.propmethod elements : elements Js_of_ocaml.Js.t Js_of_ocaml.Js.propWhile chart types provide settings to configure the styling of each dataset, you sometimes want to style all datasets the same way. A common example would be to stroke all of the bars in a bar chart with the same colour but change the fill per dataset. Options can be configured for four different types of elements: arc, lines, points, and rectangles. When set, these options apply to all objects of that type unless specifically overridden by the configuration attached to a dataset.
method plugins : 'a Js_of_ocaml.Js.t Js_of_ocaml.Js.propPlugins are the most efficient way to customize or change the default behavior of a chart. This option allows to define plugins directly in the chart plugins config (a.k.a. inline plugins).
method legendCallback : (chart Js_of_ocaml.Js.t ->
Js_of_ocaml.Js.js_string Js_of_ocaml.Js.t)
Js_of_ocaml.Js.callback
Js_of_ocaml.Js.optdef_propSometimes you need a very complex legend. In these cases, it makes sense to generate an HTML legend. Charts provide a generateLegend() method on their prototype that returns an HTML string for the legend. NOTE legendCallback is not called automatically and you must call generateLegend yourself in code when creating a legend using this method.
method responsive : bool Js_of_ocaml.Js.t Js_of_ocaml.Js.propResizes the chart canvas when its container does.
method responsiveAnimationDuration : int Js_of_ocaml.Js.propDuration in milliseconds it takes to animate to new size after a resize event.
method maintainAspectRatio : bool Js_of_ocaml.Js.t Js_of_ocaml.Js.propMaintain the original canvas aspect ratio (width / height) when resizing.
method aspectRatio : float Js_of_ocaml.Js.optdef_propCanvas aspect ratio (i.e. width / height, a value of 1 representing a square canvas). Note that this option is ignored if the height is explicitly defined either as attribute or via the style.
method onResize : (chart Js_of_ocaml.Js.t ->
chartSize Js_of_ocaml.Js.t ->
unit)
Js_of_ocaml.Js.callback
Js_of_ocaml.Js.opt
Js_of_ocaml.Js.optdef_propCalled when a resize occurs. Gets passed two arguments: the chart instance and the new size.
method devicePixelRatio : float Js_of_ocaml.Js.optdef_propOverride the window's default devicePixelRatio.
method events : Js_of_ocaml.Js.js_string Js_of_ocaml.Js.t
Js_of_ocaml.Js.js_array
Js_of_ocaml.Js.t
Js_of_ocaml.Js.propThe events option defines the browser events that the chart should listen to for tooltips and hovering.
method onHover : (chart Js_of_ocaml.Js.t,
Js_of_ocaml.Dom_html.event Js_of_ocaml.Js.t ->
'a Js_of_ocaml.Js.t Js_of_ocaml.Js.js_array Js_of_ocaml.Js.t ->
unit)
Js_of_ocaml.Js.meth_callback
Js_of_ocaml.Js.opt
Js_of_ocaml.Js.optdef_propCalled when any of the events fire. Called in the context of the chart and passed the event and an array of active elements (bars, points, etc).
method onClick : (chart Js_of_ocaml.Js.t,
Js_of_ocaml.Dom_html.event Js_of_ocaml.Js.t ->
'a Js_of_ocaml.Js.t Js_of_ocaml.Js.js_array Js_of_ocaml.Js.t ->
unit)
Js_of_ocaml.Js.meth_callback
Js_of_ocaml.Js.opt
Js_of_ocaml.Js.optdef_propCalled if the event is of type 'mouseup' or 'click'. Called in the context of the chart and passed the event and an array of active elements.
