I was experimenting with your VisadTest.java source, and discovered this:
double xMin = 1.0;
double xMax = 1.0007;
double yMin = 0.0;
double yMax = 100.0;
int xRes = 1000;
int yRes = 10;
formally setting the ranges to decimal values fixes the problem for me.
We are visualizing mass spectrometry data, and if the user wants to plot a
single mass signal, we need to visualize a narrow range of m/z values, such as
179.0551 ~ 179.0558.
1.0 to 1.00007 did not work, I think this can be expected.
Hmm, why this can be expected?
