So I’m taking Algebraic Methods (math 211) out of general interest and its turning out to be a pretty sweet course. It seems like a more proving based course.
Anyways, I’m using gnuplot just for fun now. After science fair I really was able to discover some pretty cool functionality.
The above is a heatmap/graph thing of the running time of the Euclidian Algorithm, which is what we’re currently covering in math 211. We’re doing computational complexity in the cisc course now, so the overlap was pretty cool and I felt that a graph would be fun way to spend a friday afternoon.
geez, i’m a nerd.

Hi there,
I am working on a graphing project in New Zealand for internet data.
I like the graph you have made here and need to make a similar yet more basic version.
I think we need a 2d graph that will graph a server against time and latency. So 3 variables.
* time
* server
* response time (latency)
It will be similar to the graph here: http://gnuplot.sourceforge.net/demo_4.3/heatmaps.html
Except there will be a lot more data points and the x-axis will be time, y-axis the server name and the color will be based on the latency.
I am currently using gnuplot to try achieve this but am having problems.
Any chance you could have a look at my data and suggest a way of doing it?
The data is in this format:
ns3b.int.dns.net.nz 1254355290000 4
ns3b.int.dns.net.nz 1254355890000 5
ns3b.int.dns.net.nz 1254356190000 1
ns3b.int.dns.net.nz 1254356490000 1
ns4a.int.dns.net.nz 1254355230000 1
ns4a.int.dns.net.nz 1254355530000 6
ns4a.int.dns.net.nz 1254355830000 1
ns4a.int.dns.net.nz 1254356130000 25
Where the 2nd column is the unix time in milliseconds.
There is A LOT of data this is just a snippet.
Any help would be much appreciated!
Cheers.
