In my scatterplot I would like to give a single dot a different colour when I click it. I read in the “Does plotly.js scatter/line graph handle point selection?” topic that it is possible to do this by using restyle, e.g.
Plotly.restyle('graph', 'marker.color', [['red', 'green','blue']]), which would give the first marker a red colour, the second green etc. If I have 10000 markers and want to change the colour of 1 of them, does that mean I have to pass a complete array every time? Or is there an easy way to just update the colour of e.g. marker 8750 to ‘blue’?
