Hello, I'm producing multiple dotcharts and I want each plotting area (the area containing the dots only- not the labels) to be the same width. Currently, the width of the area depends on the length of the labels. I've tried different margin arguments but they change the parameter of the whole plot (dots + labels) rather than just the dot area. A reproducible example is below; I want the dot area to be the same physical width across charts regardless of the label width. Any suggestions would be greatly appreciated!
