Method Detail
{!pv.FillStyle}
dimColor(color, type)
Gets a dimmed/gray-scale version of a given color.
- Arguments:
- {string|!pv.FillStyle|!pv.Color} color
- The color to transform.
- {string} type
- The type of graphical element for which the color will be used. Can be one of fill, stroke or text. Depending on the specified type, different effects may be used.
- Returns:
- {!pv.FillStyle} A Protovis color.
{!pv.FillStyle}
scaleColor(scene)
Gets the color to use for a given scene according to the color scale.
Usually, calling Context#delegate returns the color scale's color. However, in some rare cases, delegating already returns a modified version of it. For these cases, this method can be used to obtain a color directly from the plot's color scale.
When the associated panel has a color axis, its scale is used to encode the value of the color scene variable. If there is no color axis, the value of pvc.defaultColor is used.
- Arguments:
- {!pvc.visual.Scene} scene
- The scene.
- Returns:
- {!pv.FillStyle} A Protovis color.
