Hello,
you can try to use css padding
Like

<style>
     .webix_axis_item_y{
        padding: ...;
     }
</style>

have a scroll bar for the x axsis
You can wrap your chart into the Scrollview with “x” scrolling mode. In this case you will have to set some fixed width to the chart component: https://webix.com/snippet/4714238f

Alternatively, you can couple the chart with a Rangechart (Pro) to view a particular portion of data: https://docs.webix.com/samples/60_pro/12_rangechart/01_basic.html

Is there a way to lock the y-axis so that it’s still visible while you scroll along the x-axis?

Hey @mjg, unfortunately this is not possible (from my experience), especially considering that this an interaction between two unrelated views - you are adding a chart inside a scrollview to add a scroll to the chart (which it doesn’t have by default). For it to also interact in the way you’ve described isn’t possible I’m afraid.
