How to Draw Arrows, Lines, and Rectangles on CartesianChart with CandlesticksSeries<FinancialPoint>?

[Denis Knaack]

At first, thanks for the great work!

I am working with a CartesianChart using CandlesticksSeries<FinancialPoint>. I need to draw additional shapes like arrows above or below the candlesticks, as well as lines and rectangles on the chart. I couldn't find any examples or documentation on how to achieve this.

I have searched through the official documentation and example projects and looked for similar issues in the repository, but I have not found a solution. Any help or pointers to the relevant documentation would be greatly appreciated.

I am using it in my WPF application.

Thank you!
