Hi,
The filter code, along with most all of timeline is courtesy of David H.
I'm sending this from the road, so I don't have access to the src. My
recollection is that the filtermatcher function returns true or false for event
to be included or not. Your code sample shows where the fultermatcher function
is registered with timeline, you are not showing the implementation of the
filtermatcher function itself.
To change the sense of the filter function, just change the function by
inverting its output value. You don't need to change timeline itself, just your
function. Hope this is clear, ask if not.
Regards,
Larry

Subject: examples.js - filter/highlight
I have been very pleased with the functionality offered by the filter
routines. Many thanks to the author (whoever that might be).
What I want to do is invert the action of the filter, such that it
hides that which I type in, leaving unmatched events visible.
I am afraid my coding skills lie primarily in perl, not javascript
however. Thus, if there is someone who could point me in the right
direction, I am pretty sure I can modify my own copy of examples.js to
do what I would like it to do.
Following is the piece that I think does the work, but I don't know
how:
104 for (var i = 0; i < bandIndices.length; i++) {
105 var bandIndex = bandIndices[i];
106 timeline.getBand(bandIndex).getEventPainter
().setFilterMatcher(filterMatcher);
107 timeline.getBand(bandIndex).getEventPainter
().setHighlightMatcher(highlightMatcher);
108 }
109 timeline.paint();
Thanks in advance for any constructive input.
