Hello,
It's very interesting. But unfortunally it doesn't work. When I added csv file - appear error.

Input string has incorrect format.

can you send me your csv file? 

Hallo dickeytk, I was trying to run this app too, but I have found the same error message as easy_admin (but in Czech language). Here is a sample csv file, I was trying to open ~ 10 files, but withou any success:
http://rapidshare.com/files/213424761/acc2009.3.22_2_3A3_3A29.csv.html
Error message:
http://www.postimage.org/image.php?v=Pq8oW90

Any ideas how to solve this problem? :]

What a great idea! I would love to see that too! I have no idea how to do it but keep trying!

- i also get the "unhandled exception" like others here
- the log output is below

- in the meantime somebody might come up with an Microsoft Excel graph equation to apply on the CSV data to turn the numbers into simple Excel graph

LOG OUTPUT:

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Thanks dickeytk for this wonderful tool!!

It works on Windows vista... Please see the attached image:

I used a file named "acs2009.**********.csv" as input.... the "*" represents that it could be anything.
I guess that the .csv filename should start with "acs".

The first few lines of the file look like this:

Hope that will help someone! :-)

Great! That worked for me! My graph is a lot messier though, do you use the accurate sensor or the attached method?
And thanks for making the tool TS!
