Bug report for TimePeriodValues

The getMaxEndIndex() function does not work properly if you have two entries with the same time period.

Not sure if this is intended behavior or not

dave, any ideas about periodaxis class? I will look at this when I get time. I didn't write the segmented timeline code, so I don't know it so well. I know it works well for some people and not well for others - in the medium term, I'd like to find an alternative implementation that's easier to debu...

instead of messing around with this segmented timeline, how easy/difficult would it be to have an OHLCSeries that does not take into consideration the date of each item, but simply appends each item to the series giving it a uniformly increasing X value?

I figured out how to use SegmentedTimeline with intraday...

a 78 minute chart is 1/5 of a 6.5 hour trading day (9:30 to 4:00)

everything works from monday to friday--no gaps, but weekends do not seem to be excluded at all.
