Comma Seperated data set

Hello,

I am trying to create a chart from a data set that contains 20 comma separated data points per row. To give a brief description, we receive a data sentence 1/second from a USB Device. That data sentence contains 20 distinct data points (a 20 Hz sampling rate), plus some additional information. I only care about fields 4-23. An example sentence looks like:

$<Type>,1,PLOT,207,206,206,205,205,205,205,206,208,210,211,210,209,208,207,206,206,205,205,205,DC,106,AC,018

Any help or suggestions would be appreciated file.

What kind of chart do you want to create? are there multiple series here or just a single series? With a little more detail we can get things laid out for you quickly.

Only a single data series. Either a scatter (with trend line) or a line chart is what I am thinking with the x-axis being time. I am using a flat file for a data source, so I know the first record processed will be time 00:00:00 and each line is 1 second a part. The outcome should be a waveform.

Also, the data sets can be pretty large, so I would also like to be able to specify a time range to build the chart from to improve granularity.

Thanks for the quick response and let me know if you need any more information.
