Mark, this is a bit different than the way I figured I would
implement multi-data tick charts. Just to make sure I understand
what you're doing here:
>From your comment on the last screen shot ("...the data streams are
totally independent of TIME") I suspect that you're displaying the
N-tick bars basically as they'd look if you stacked 3 independent TS4
N-tick charts above each other -- none are sparse, all are lined up
at the right border, and they all have different time scales. Right?
(& if so, does the time scale at the bottom of your chart indicate
the time scale for the primary "Data1" series?)
I haven't put a lot of thought into how I would implement multi-data
tick charts, but I sort of figured I would use the same time scale
for all data series, and anchor each bar to the closing time for the
bar. Obviously that would result in sparse bars (with space between
the bars on the slower series), just like a 5-min / 10-min chart in
TS, but that's probably not what you want. I'll have to think a
while about how you interpret & use parallel tick charts with wildly
different time scales. Basically the X axis represents "equal volume
chunks" instead of "equal time chunks" as on a standard multi-data
time-based chart.
(Actually I guess you're only charting "equal volume chunks" if you
are plotting the same # of ticks in each data series. If you plot 5-
tick bars on one series and 10-tick bars on another, the 10-tick
series represents 2x the volume as the 5-tick chart shows in the same
X-axis space.)
Hmmm. :-)
