org.das2.graph.EventsRenderer

Draw colored horizontal bars for the dataset, marking events datasets or modes of the data. This expects a QDataSet with the canonical scheme:

{@code
    Events[:,BUNDLE_1=4] where the columns are:
      BUNDLE_1=startTime,stopTime,Color,Message
    startTime,stopTime are in some time location unit.  stopTime may also be an offset from startTime (e.g. seconds)
    Color is an int, that is either 0xRRGGBB or 0xAARRGGBB.
    Message is any datum, so typically an enumeration unit is used.
}

Note this also contains systems for coloring data in old schemes, such as the colorSpecifier interface and textSpecifier. These should not be used when a dataset will be sufficient.

setColor

setColor( java.awt.Color color ) → void

set the color to use when the data doesn't specify a color. If an alpha channel is specified, then this alpha value is used, otherwise 80% is used.

Parameters

color - a Color

setColorSpecifier

setColorSpecifier( org.das2.graph.EventsRenderer.ColorSpecifier spec ) → void

set this to be an object implementing ColorSpecifier interface, if more than one color is to be used when drawing the bars. Setting this to null will restore the initial behavior of drawing all bars in one color (or with rank 2 bundle containing color).
