Is drawing on canvas
drawing bar chart with random data generated by button click
chart is right way up, shows horizontal lines. (Only displays in debug, must fix)
replaced bars with scatter plot
shows sd and mean. Uses Gaussian random for testing.
Button loops 300 tests. Added a DataGenerator.
Tests executed as AsyncTasks, run by a parent AsyncTask
Plotter.refresh runs on UiThread, now it all works in run and debug modes.
Thread.yield in refresh method
