DIY platform - Any C# coders? Need info, not code!

Hi i want to create a type of cluster chart on C#, probably windows form. I know that .net has a chart, but i want to create mine. The problem is that i cannot i understand what i need. And i mean:

1) Are those clusters of clusterdelta, text label objects or are something else (any other type of pre built chart type)
2) If they are i heard that .net has a limit of 10000 objects on user so i will must have always plot labels below that limit?
3) How to terminate axis (time price) again i will plot labels??

Thank you and sorry for the confusing question.

example

My guess is that it's a table with conditional formatting on the cells. That would be a lot easier to manage than a ton of label objects.

The clusters have to be based on a certain principle and some related formulas. coding can then be derived in C#.

GUYS thank you first of all for giving time and thought to answer me. But still its not clear to me, most of that type of charting platforms are written on .net, so i mean is there any type of chart they already use or they reach on this level using separated objects (like labels)?
