Hi John, Hmm.... I have 3 use cases where I want to isolate individual tick labels and make them invisible: 1) the first tick (0; for stacked plots) 2) the last tick (-1; for stacked plots) 3) every other tick for the last few ticks (e.g. -2, -4, -6; for a log-scale axis with large tick labels, which can overlap on one end) Is there a way to force some sort of pseudo-draw event, such that the sizing is done and the ticks are created from the protoTick, but the draw isn't actually performed by the backend? That way one could set the visibility property rather than wrap the Formatter. Thanks, Mike ------------------------------------------------------------------------- Using Tomcat but need to do more?
