Is it somehow possible to update an existing candle-plot without redrawing the whole chart?

Meaning I want to add a candle when new data has arrived. Everytime redrawing the whole chart is rather slow.

If you save the handle to the plot, you can access its Data property

h = candle(ax, someData)
h.Data(end+1) = [1 2 3 4];

Ah I see, the candle is appended automatically at the end. Probably works through the included datetime. Nice!

Thank you very much!
