zingchart data grouping and down sampling

I'm currently building an application with zingchart with vary large set of data(500,000 pts plus). It has great performance, however, I found that there seems to be doing some data grouping or downsampling to enhance the performance. When this happens, the data is not rendered or displayed correctly.

Is there a way I can turn this feature off?

"plot" : { .... "exact" : true, "smart-sampling":true, .... }

Leaving just exact:true will paint all nodes (500K) so it will be slow. The smart sampling will sample the data, but in such a way that you will see spikes that you would otherwise miss on a "blind sampling"

I believe 

plot: {
  exact:true
  ...
}

will do the trick. Any and all modifications you will need (for this issue) will be inside of the plot object.

One plot example, if you have many nodes you can turn off events for a majority of the nodes with maxTrackers:1000. This would benefit performance and as you zoom in you will get the events back on the 1000 nodes in view. I bring this up so you know there is a lot more configurability than you currently know about, so feel free to ask more questions!
