After applying 3D plot, it became slows.

Hi guys, I really need some help from you guys.

I'm recieving some data from DAQ devices and after processing these data from ADC to what i want to express like distance,

I plot data to 3D graph using 3D Scatter plot helper. 

Before Applying 3D plot helper, data aquisition and data processing was not slow (almost sensable in real time),

but atfer that, 3D plot Graph's speed remarkably slows down.

I think that data flow which go into 3D plot helper has improper code.

How can i get help and what can i change?

please help me!!
