## org.das2.graph.DasPlot

DasPlot is the 2D plot containing a horizontal X axis and vertical Y axis, and a stack of Renderers that paint data onto the plot. It coordinates calls to each Renderer's updatePlotImage and render methods, and manages the rendered stack image to provide previews of new axis settings.

## DasPlot( org.das2.graph.DasAxis xAxis, org.das2.graph.DasAxis yAxis )

create a new plot with the x and y axes.

## PROP_LEGEND_WIDTH_LIMIT_PX

## PROP_TITLE

title for the plot

## PROP_FOCUSRENDERER

property name for the current renderer that the operator has selected.

## PROP_MULTILINETEXTALIGNMENT

property name for multiline labels, the horizontal alignment, where 0 is left, 0.5 is center, and 1.0 is right.

## DUMP_TO_FILE_ACTION

Action to dump the first (0th) renderer's data to a file.

## INFO

These levels are now taken from java.util.logging.Level. Generally INFO messages are displayed.

## WARNING

mark the log message as a warning where the operator should be aware.

## SEVERE

mark the log message as severe, where an error condition has occurred.

## PROP_DISPLAYTITLE

turns the plot title off or on.

## PROP_BOTTOMDECORATOR

## PROP_TOPDECORATOR

## PROP_CONTEXT

property where the plot context can be stored.

## PROP_DISPLAY_CONTEXT

necessary place to put the range of the data actually displayed. The context is the controller, and the displayContext closes the loop. This is mostly here to provide legacy support to Autoplot which abused the context property as both a write and read, and note there's a small problem that displayed items may have different display contexts. So this property should be used carefully, and generally when just one thing is visible.

## PROP_RENDERERS

## PROP_LEGENDPOSITION

the location of the legend position, which can be one of the four corners, or outside and to the right of the plot.

## PROP_LEGENDRELATIVESIZESIZE

relative font size for the legend. For example, -2 will use sans-8 when the plot font is sans-10.

## PROP_LEGENDFONTSIZE

## PROP_FONTSIZE

## PROP_DISPLAYLEGEND

true if the legend should be displayed

## PROP_DRAWBACKGROUND

the background should be drawn, if alpha is >0.

## PROP_DRAWGRIDCOLOR

if not transparent, draw the grid in this color. Otherwise the grid is drawn with the tick color.

## PROP_DRAWGRID

If true, faint grey lines continue the axis major ticks across the plot.

## PROP_DRAWMINORGRID

If true, faint grey lines continue the axis minor ticks across the plot.

## PROP_DRAWGRIDOVER

if true, then the grid is on top of the data.

## PROP_LINETHICKNESS

## PROP_PLOTVISIBLE

## PROP_OVERSIZE

boolean property indicating that the data outside the axis bounds is rendered, to smooth animation when the axis is panned.

## PROP_LONGTITLES

## PROP_LOG_LEVEL

the log level for the messages on the screen.

## PROP_PRINTINGLOGLEVEL

the log level to indicate the log level when printing.

## PROP_LOG_TIMEOUT_SEC

number of seconds to show the log messages. If Integer.MAX_VALUE/100 or greater then there is no timeout.

## PROP_ISOTROPIC

true if the x and y scaling (pixel:data) ratio is locked together.

## PROP_DRAWDEBUGMESSAGES

draw a purple box in the lower right corner indicating the number of times each renderer has updated, rendered, and the plot itself has painted.

## addCustomizer
