During multichart analysis I struggled to get the annotations to the correct position. These were the challenges: - How to get an annotation to each subplot of a chart-grid? - I had log-Y-axes and I missed that the annotation value must be logged as well - for coupled axes, the XRef and YRef must be set differently as if the axes were uncoupled The [annotation documentation](https://plotly.net/reference/plotly-net-layoutobjects-annotation.html) could be updated with descriptions of how to solve these problems.
