Passing large data to the chart

[User (Legacy)]

Hi! 

When I create a chart I have to pass every point to the chart. 

If the number of points and series is very large this process takes very 

long time. 

Also, this consumes lots of memory as I store all the data in internal 

structures and then duplicate them by passing to the chart. 

Is there any ways to avoid these problems? 

For example, it would be great to pass data on demand, ie when the chart 

need to draw a point (or range of points) it would send a notification and 

the app would return data. 

Is it possible?
