regions's Issues

Button function

The run and pause buttons currently don't work. Pause doesn't show and run will trigger another thread.

Can't load my log

Hi, I've replaced the testdata.log with a G1 log produced by my application. The application starts but with an empty canvas. When I press the play button it throws an exception.

Whith your test data the application seems to work correctly.

My G1 conf is as follows:

-showversion -XX:+PrintCommandLineFlags
	-XX:+PrintGCDateStamps -XX:+PrintGCDetails
	-XX:+ParallelRefProcEnabled -XX:+PrintReferenceGC
	-XX:+PrintTenuringDistribution -XX:+PrintAdaptiveSizePolicy
	-XX:+DisableExplicitGC -XX:+UseG1GC -XX:MaxGCPauseMillis=250
	-XX:InitiatingHeapOccupancyPercent=45

The exception is:

File loading

Active the file load button. I fear this may not be as easy as it sounds as the grid will be constructed until the file is loaded. Grid shape may change when a new file is loaded.

Annotate CSet region

Annotate any regions that will be included in the CSet. Currently that data is not collected in the model.

Add legend

describe region type and CSet annotation

Build system

Needs a non-de build system

help screen

Add a help screen

3D view

The idea here is to add some idea of how full each region is. Current thinking the view would be tiled and converted to a 3D perspective where the height of the rectangle could be used to indicate fullness.

data popup

Have the data associated with a rectangle popup on mouse over.
