Hello, I would like to create something similar with Dash Plotly.

 ![Screenshot 2021-01-10 at 23.30.48](https://us1.discourse-cdn.com/flex024/uploads/plot/original/2X/3/391b66838d73cde5d8d45e084f33a6f10557b349.png)

I would like to draw a horizontal line across candlestick chart, based on the values from a dataframe and display that value as “annotation” attached to a line.

I’ve managed to draw horizontal shapes based on values from a dataframe but that Limit and price label/annotation on the left is essential and I have no idea how to achieve it.

Is that possible in Dash/Plotly and could you please point me in the rigth direction please?  
Thank you

Do you want to show these annotations permanently or on hovering?

Permanently. Or at least on one of the y axis.
