I'm testing a communication channel where I vary 2 parameters, call them X and Y. I include the values of X and Y in the message and I send N messages for each pair of X and Y. Each message either passes through the channel or does not - there are no partial messages. At a given pair of values for X and Y I get N or fewer (or no) successful messages.

My output file consists of rows of successfully received messages with the message data consisting of the values for X and Y. I'd like to create a 3D plot that shows the number of successful messages for each value of X and Y.

For example, I might have this:

2,3
2,3
2,3
3,3
3,3
3,3
3,3

In this case I want to plot two points, one at (2,3,3) and one at (3,3,4) where the z value is a count of the number of identical lines.

I don't have to worry about non-contiguous sets of identical lines because my source data never does that.

Can anyone suggest a good way to implement this in gnuplot?

Thanks,
Bret
