Each interface captures the content of a particular type of science content.

Jot list of data types of potential interest:

Note: all data interfaces are implied to be immutable (no mutator methods on the interface; client usage can expect no changes)

linear data

• number of values
• values (1-D)
• x-axis values(not necessarily a gauge!) (time
• possibly gauged (time, or more generally non-strictly monotonic
• different flavors: scatter plot data, line plot data
• uncertainties
• units
• name of x variable; name of y variable
• description
• fill value
• max x-gap for connecting dots OR max gap function of x OR max gap as function of index
• plotting metadata: plot color, symbol, line thickness, axis labels

Simplest Interface: XYData

• size()
• getX(i)
• getY(i)

Then have a separate interface with:

EnhancedXYData extends XYData

• isFill(index)
• xunits, yunits (TBD probably some object)
• name of x variable; name of y variable
• labeler for axis values
• Optional getUncertProviderX()
• Optional getUncertProviderY()

interface UncertProvider {

 double getUncertPlus(i)
 double getUncertMinus(i)

}

EnhancedXYDataWithUncert extends XYData

spectrum / 1D histogram

• has x bins
• has y data values for each bin
• has uncertainties?

spectrogram / 2D histogram

• not just with functions of time

trajectory
