Prevent the word "Trace" appearing in annotations

Hi all,
I am building as test in the hope that we can use plotly.
I need a multi line with points annotated along the line.
I found a sample that I have begun to play with. "Main sources for news.
I can not find out how why the annotations that appear on hover are labelled trace 1, trace 2, etc
I am hoping to show users a label for each line and if we do further label it in annotations then surely the line label is what I would want to show them

Can anyone advise?



Those are the default trace "name" value. You can override them as in or choose not to display them on hover by setting hoverinfo: 'x+y+text' in both your traces.

That did it. You are a gent.
