Class: c3.Polar
| Defined in: | js/c3-polar.coffee |
| Inherits: | c3.Chart |
Overview
A chart that uses a polar coordinate system.
r is the radial dimension and t is the angular dimension.
The top is 0 degrees and the range is expressed in radians so a full circle is 0 to 2Pi.
A polar chart can contain multiple layers.
Variables Summary
- version =
-
0.1 - type =
-
'polar' - layers =
-
[][Array<c3.Polar.Layer>] Array of polar layers
- data =
-
[][Array] Default data array for layers in this polar chart. This can be set for each individual layer or a default for the entire chart.
- r =
-
undefined[d3.scale] Scale for the radial dimension. Please set the domain(), c3 will set the range(). This can be set for each individual layer or a default for the entire chart.
- t =
-
undefined[d3.scale] Scale for the angular dimension. Please set the domain(), c3 will set the range(). This can be set for each individual layer or a default for the entire chart.
- angular_range =
-
[0, 2 * Math.PI][Number] Angular range for the polar chart in radians. 0 is up and the direction is clockwise. Defaults to the entire circle, which is [0, 2Pi]. Adjust this range to rotate the chart or use a semi-circle (e.g. [-Math.PI/2, Math.PI/2])
- zoomable =
-
false[Boolean] Enable this polar chart to be zoomable with the mouse wheel or touch pinching gesture
- zoom_extent =
-
undefined[Array
] Array of minimum and maximum zoom scaling if zoomable is enabled - layer_options =
-
undefined[c3.Selection.Options] Options to apply to each layer. For callbacks, the first argument is the layer object and the second argument is the index of the layer
