Yuck!

The problem you’re having with setYValues(double, double) seems to be a rounding issue. I’ll see if that can be handled more cleverly in a future release.

I am using setYValues(Object[]) method, where the argument is an array of doubles starting from 0.0 to 0.9. I am still getting the same type of heatmap. No change. :/

I tried using setYValue(double, double), but it only works partially. Meaning that numbers are all messed up and are over written over one another. Take a look: http://dl.dropbox.com/u/9008927/aBTLA_5F5_mutant_HC_DTT_IAA_GluC_37C_ON_top10_msmsIT_042308_2_b_vs_y_charge3.png

You can reverse the y axis in two ways. The easiest of which is to call setYValues(double, double) with a negative interval between each value. In the example above, this means adding the following line:

map.setYValues(data.length-1, -1.0);

The other approach is to use setYValues(Object[]) and pass an array of the values to plot along the y axis which you generate yourself.

I have one question for you: Heatmaps I generated using your lib are like the red and blue example above, meaning the y axis scale does not start from 0 as the bottom value. How do I make it so that 0 is the bottom value of y axis? Maybe I overlooked the code and am not seeing a function in your lib that allows me to do that. I really appreciate your help. Thank you in advance!

i, j = j, i // Swap i and j.

I haven’t really had the opportunity to do much more than dabble with it, but I really like what I have seen so far.

“… the point is that Go gives you concurrency, a concurrency specifically suited to modern systems programming. It gives you concurrency that runs close the metal, but it also gives you a new breed of concurrency you won’t find in other languages, including Erlang. And this comes from goroutines.

Goroutines aren’t threads or lightweight threads. They aren’t callbacks. They’re processes within a single address space that can communicate with each other. Communication is provided by “channels” running between goroutines, and these channels can transmit multiple signals at once. You can use a channel to send any variable, including other channels.”

Sounds quite Occam-Pi like.

Or to put it another way, why not just use C++ or Python, whichever is more appropriate?
