How to adjust center axis width in a butterfly chart in Tableau

Question

I'm currently working on a butterfly diagram. With the "Text" type, I generate a centre zero axis. Except for one issue, everything goes smoothly.

I want to modify the width of the central axis since it is too wide. But I'm not sure how to go about doing it.

When I reduce the centre axis, I also shrink the left and right axes. The width ratio appears to be constant.

Concatenated by Dashboard

Instead of using a single worksheet, we may utilise a dashboard to concatenate the centre margin.

Right-click on the sheet tab and replicate three copies to divide into three worksheets. Remove the remaining components from each worksheet.
Concatenate three segments into a Dashboard and drag them to the appropriate spots.
Change the size of the dashboard to 1200 x 4500 pixels. dashboard concatenated
Set Standard for the left and right portions, and Fit Width for the central segment. After that, resize them to fit into a logical arrangement.
Right-click Legends and choose Floating, then drag them to the desired location.
Clean up the graph: Only the left title should be kept, while the others should be removed. The left and right axes should be visible and renamed."
