I got a problem while using ApexChart and struggling so much on how do I could remove the one that I give 'X'?

So basically, what I want to achieve is like the light blue line that I draw. On ApexChart, there's a specific styling for this - Curve's Stroke.

I want to use Stepline and Straight at the same time but I don't know how. So what I did is using 2 different series (dummy random data) with line and area chart type, then the first one using stepline curve and the second one is using straight.

It turned out I almost achieving what I need to do but, the problem is the 'X' blue mark. I didn't want it like that. I want it just start a straight line after that specific last value/category/you know what I mean.

Is there any workaround for me to look? Can anyone help me? I've been struggling about this for days and I'm getting crazy about it.
