Hi,

I am trying to create an auto-loop functionality for the animation slider.

To achieve this, I need to know when the slider reaches the end so that I can add an auto-click functionality to the play button.

Is there anyway I can detect when the slider reaches the end or return the slider value dynamically?

Thank you

Found the answer! 🙂

Here’s the code if anyone is interested in using it 🙂

myPlot.on(‘plotly\_sliderchange’, function(e){  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;console.log(e.step.label);  
}
