[Kst] How to do a simple graph in kst

[Bill Gee]

HELP!!!  Can anyone here help me out?  What am I missing?

I've been beating my head against every graphing program I can find trying get 
one that will create a simple graph.  So far I have not been able to figure 
any of them out.  They'll do complex stuff but not simple.  Urgh!

The data I want to graph is from water level loggers.  It is organized by date 
and consists of a water depth, water temp and air temp taken every 15 minutes 
over a period of about 8 months.  It is all in a txt file.  Here is a sample 
of the first few lines of the file:

"Time","Water Temp","Water Depth","Cave Air Temp"
Sat Oct 28 10:45:00 2006,56.75,1.03,60.02
Sat Oct 28 11:00:00 2006,56.58,1.04,58.65
Sat Oct 28 11:15:00 2006,56.58,1.03,57.96
Sat Oct 28 11:30:00 2006,56.58,1.03,57.61
Sat Oct 28 11:45:00 2006,56.58,1.03,57.27
Sat Oct 28 12:00:00 2006,56.58,1.02,57.1
Sat Oct 28 12:15:00 2006,56.58,1.03,57.1
Sat Oct 28 12:30:00 2006,56.58,1.03,56.92
Sat Oct 28 12:45:00 2006,56.58,1.03,56.92
Sat Oct 28 13:00:00 2006,56.58,1.03,56.92
Sat Oct 28 13:15:00 2006,56.58,1.03,56.92
Sat Oct 28 13:30:00 2006,56.58,1.03,56.92

So here is what I am fighting:

1) How the heck do you get dates to become the X axis?  I've tried every date 
format I can think of, but all kst will do is either give me garbage or give 
me what looks like about 10 seconds around midnight Jan 1 1969.  If I use the 
internally generated INDEX for the X-axis, kst will make a nice plot of the 
data.  Looking at dates that run from 0 to 22,000 is pretty useless, though.

2) How do you get multiple Y ranges?  The water depth ranges between about 1 
and 3 feet while the temperatures are in the 55-62 range.  I want both on the 
same plot with appropriate scaling.

3) I have other sets of data which do not exactly line up time-wise.  Rainfall 
events, for example ...  Every .01 inch generates an event with a time stamp.  
Is there a way to plot these events mixed in with the other data in 
time-sequence order?

My clue buffer is in an underflow condition.  Thanks for any help you can 
give.
