I assume you are referring to the
volatility action? There is not an easy way to adjust y-axis directly in the visualization, and I have opened an issue to add this feature at some point in the future.
For now, it would be possible (with some difficulty for beginners) to adjust the y-axis limits by using the “vega editor” to edit your plots. Use the visualizer to navigate to the feature you want to visualize, and format the plot to the extent that you desire. Then click “vega editor” to open the plot in vega editor, which is an external program for editing the plot data — you will need to read up a little bit on how vega works (the editor page will link to documentation), but it should be possible to define yaxis limits in there somewhere.
Thanks for suggesting this feature!
