Dear Andrew,

As mentioned in the previous question. we are getting ready to implement a comprehensive annotation and labeling functionality to our application. Although I know how to add scalable custom-annotations (your team guided us with the implementation in the past), an important part of of annotation functionality is. ability to edit the annotations. But I am having trouble accessing and interacting the the annotations.

How can I access the svg polygon nodes from the custom annotation and drag and move them? I have attched a video to show the existing functionality.

I have a real-time updated chart with multiple series. Is it possible for me to add a custom annotation to the chart by just providing the x1 value? i.e. The y1 value will be the y value of the data point in certain series with the provided x1 value. It will look like that the annotation will be sticked to the series with a fixed x1 value while the chart is updating.

Hi SciChart Team,

Thank you all for your help and support.

I finally got the multiple symbols on the stock chart with reference to this and with this clear explanation
IAnnotation annotation = builder.newCustomAnnotation().withContent(R.layout.example_custom_annotation_view).withYAxisId(PRICES).withPosition(i, prices.getHighData().get(i)).withVerticalAnchorPoint(VerticalAnchorPoint.Bottom).build();

The above code worked for me and hope it helps to others too who all are trying this.

Hi Yura,

Thank you for the answer here

I already did tried that way before also but was unable to display the custom annotations, even though I give the YAxisId the symbols are not visible on the chart…

I would be really grateful if you could help me out with this please
