I’m trying to stream data (line charts) using extendTraces and the code looks like the following:
Plotly.extendTraces(graph, { x: [[time], [time]], y: [[data[‘ap’]], [data[‘bp’]]] }, [0, 1])
However when I try to add text to the same, I get an error. Following are the line and the error I get:
Plotly.extendTraces(graph, {x: [[time], [time]], y: [[data[‘ap’]], [data[‘bp’]]], text: [[data[‘a’]], [data[‘b’]]]}, [0, 1])
plotly.min.js:7 Uncaught Error: cannot extend missing or non-array attribute: text

Am I doing something wrong here?
