Get markers of current selected zoom area

[fishbonebob]

Hi Plotly community,

is there a way to get the index of all visible markers after zooming in to a graph.

This is my graph:

After I zoomed in, I see for example these points:

So the function should return the index oft the 3rd and 4th markers of the blue line and the 1st and the 2nd index of the orange line.

Any help would be very nice!

Thanks!!

Okay, after doing some research. I found such function is not implemented jet:

Get datapoints in currently zoomed view

I think I have a similar question in that I would like to select datapoint on the scatter plot for filtering purposes. I have created the scatter plot as https://plot.ly/r/shinyapp-plotly-events/ and using lasso or box, I get those datapoint I want to exclude return on screen. I am just wondering if there is a way to save the return point into R directly as a vector for downstream processing. At the moment, I need to cut and paste those return value into a text file… I guess there must be a …

I’v done it like so, quite sinple:

 myPlot.on('plotly_selected', function(eventData) {
console.log(eventData.points);//<---- all markers

//after that zoom in manually
Plotly.relayout('myDiv', 'xaxis.range', [+new Date(eventData.range.x[0]), +new Date(eventData.range.x[1])])
});

Hmm, dont like this solution though.
It’s too hacky and you can’t for example zoom back out, with the double click…
