Hi I wish to create a kind of audience chart on C#, likely windows form. I know that .net includes a chart, but I would like to create mine. The problem is that I cannot understand what I want. And mean:

1) Are those clusters of clusterdelta, text tag objects or are something else (some other sort of pre constructed chart kind )
2) If they're heard that .net includes a limit of 10000 objects on user so I will have to have always plot labels under that limit?
3) How to terminate axis (time price) again I will plot labels??

Thank you and sorry for the perplexing question.
