How to draw Candlestick chart in viewbox? I tried a lot and failed

[David Hoese]

Do you have some code for what you've tried already? There is nothing built in to vispy to do this. You'd have to do it yourself.

Hi,

David is correct, there is no special candlestick already implemented in
vispy. But you can try to build one of your own by taking MarkerVisual
('hbar' or 'vbar') at least for the body of the candles. You could try
to get the wicks with LineVisual, but this would need some treatment of
the segments.

That would only need two visuals and should be reasonable fast (taken
with a grain of salt).

Hi,

thanks for sharing. This looks very promising already. We could think
about adding this as an example to vispy if you are interested to share
your results.

Looking forward to seeing more of this.

Cheers,
Kai
