@grishka Consider drawing data directly into view’s context, not bitmap at least.
1. New data comes.
2. Gets analysed and mapped into comfy numbers for drawing.
3. Switch to main thread, set it onto your custom view.
4. While on main thread, set needsDisplay on that custom view.
5. When appropriate, you `draw` method will be called in custom view. There you just take comfy numbers and draw directly on context.
