Hi Iwo,

Thank you for the helpful tutorial and nice code.
I have two question though.
1. When I use the scrolling (setting minimum and maximum), if I have something drawn on the chart (on it CartesianDataCanvas) and if the draw goes out of sight, next time I scroll back to its position, it is gone!
I use addDataChild to add a graphic.
2. Something similar happens if I add another LineSeries with less data. While scrolling, the line segments can disappear at once.
Can you please advice on this?
Thanks!

Hi, Excellent work, very helpful. I have a question about performance with Large Data Sets, I have a chart with 10000+ data points, it is slow when Scrolling and zooming the chart, but the CPU and ram is not fully in use.
Thx

hi!
Thank you for your work. I have a question:
1 I use your code to work with CandlestickChart. This chart is updated on a timer. How to make sure that-be when you add a new value, old moved to the left (with the axis Y)? There is now a zoom-out the whole chart.

Thank you.

Terrific!

Do you mind if I slightly changed your components and put your post on the Russian language to keep a reference to the source?
