Merge lp://staging/~richardw/jarmon/independent-ds-transformers-1188220 into lp://staging/jarmon

I just tested it on our setup - it has the desired effect, I'm almost completely satisfied, but other thing turned up.

When the resulting graph is mostly negative (let's imagine Y-axis has max = 100 and min = -1000000, in other words, there is a lot more TX than RX for example), it sets the prefix incorrectly (according to the max value only) and it generates lot of steps.

I propose using the greater value of axis.min and axis.max in "this.options.yaxis.ticks" instead of axis.max only. Other possibility is to use difference (axis.max - axis.min), but that seems a bit more tricky to me.

Other than that it works fine, thanks a lot!

Just to be a bit more precise - I don't propose using greater value, but the value that is farther away from zero :)

It seems a quick fix, could you add this small change? Then I'll approve :)

< if( Math.pow(1000, si+1)*0.9 > axis.max ) {
---
> if( Math.pow(1000, si+1)*0.9 > axis.max && -(Math.pow(1000, si+1))*0.9 < axis.min) {

I applied your diff and it does give properly spaced negative ticks, but I couldn't clearly understand why.
I came up with a slightly different condition which seems to have the same effect and which I think I understand.

See what you think and let me know if it works for you.

I also added a couple of extra step sizes because (on my system ) I was graphs with only two tick labels.

Thanks again for testing.

Works as expected, great job!
