method display : bool Js_of_ocaml.Js.t Js_of_ocaml.Js.propIf false, do not display grid lines for this axis.
method circular : bool Js_of_ocaml.Js.t Js_of_ocaml.Js.propIf true, gridlines are circular (on radar chart only).
method color : Color.t Js_of_ocaml.Js.t Indexable.t Js_of_ocaml.Js.t
Js_of_ocaml.Js.propThe color of the grid lines. If specified as an array, the first color applies to the first grid line, the second to the second grid line and so on.
method borderDash : line_dash Js_of_ocaml.Js.propLength and spacing of dashes on grid lines.
method borderDashOffset : line_dash_offset Js_of_ocaml.Js.propOffset for line dashes.
method lineWidth : int Indexable.t Js_of_ocaml.Js.t Js_of_ocaml.Js.propStroke width of grid lines.
method drawBorder : bool Js_of_ocaml.Js.t Js_of_ocaml.Js.propIf true, draw border at the edge between the axis and the chart area.
method drawOnChartArea : bool Js_of_ocaml.Js.t Js_of_ocaml.Js.propIf true, draw lines on the chart area inside the axis lines. This is useful when there are multiple axes and you need to control which grid lines are drawn.
method drawTicks : bool Js_of_ocaml.Js.t Js_of_ocaml.Js.propIf true, draw lines beside the ticks in the axis area beside the chart.
method tickMarkLength : int Js_of_ocaml.Js.propLength in pixels that the grid lines will draw into the axis area.
method zeroLineWidth : int Js_of_ocaml.Js.propStroke width of the grid line for the first index (index 0).
method zeroLineColor : Color.t Js_of_ocaml.Js.t Js_of_ocaml.Js.propStroke color of the grid line for the first index (index 0).
method zeroLineBorderDash : line_dash Js_of_ocaml.Js.propLength and spacing of dashes of the grid line for the first index (index 0).
method zeroLineBorderDashOffset : line_dash_offset Js_of_ocaml.Js.propOffset for line dashes of the grid line for the first index (index 0).
method offsetGridLines : bool Js_of_ocaml.Js.t Js_of_ocaml.Js.propIf true, grid lines will be shifted to be between labels. This is set to true for a category scale in a bar chart by default.
