Class EnvPlanePlotter

java.lang.Object
  uk.ac.starlink.ttools.example.EnvPlanePlotter

All Implemented Interfaces:

SinePlot.PlanePlotter

public class EnvPlanePlotter
extends Object
implements SinePlot.PlanePlotter

PlanePlotter implementation that uses the name/value pairs in the same way as the STILTS application command-line interface to set up a plot. This is much easier to do than the alternative, since the large majority of the options will assume sensible defaults if not set. It allows pretty much the same capabilities. However, it does not offer compile-time safety: there is no guarantee that a plot set up like this will not generate a run-time error.

Description copied from interface: SinePlot.PlanePlotter

Creates a JComponent holding a plot of the data in the first two columns of the supplied table. This plot is live, and can be resized (as required by Swing) and panned and zoomed (by various mouse drag and wheel gestures).

The dataMayChange parameter is used to determine whether the plot positions should be cached or not for repaints, either as required by Swing move/resize actions or as the result of the user navigating around the plot. It's always safe to set it true, but if the data is static, setting it false will give better performance.

Specified by:

createPlotComponent in interface SinePlot.PlanePlotter

Parameters:

table - table to plot

dataMayChange - true if the table data may change during the lifetime of the plot

Throws:

InterruptedException

IOException

uk.ac.starlink.task.TaskException
