What limitations do the charting components have?
Most limitations are related by the amount of available RAM and CPU, GPU, etc. but in general, it is best to load fewer than 50,000 bars, fewer than 1,500 objects (buy/sell/lines, etc.) and it is best to display fewer than around 50 charts at once (all charts are thread safe). If you want to display hundreds of thousands or millions of bars, then you must page through your database. This is what most charting applications do.
