Adjusting spacing between figure categoriesIs there a way to adjust the spacing between categories within figures. I frequently make bar graphs and dot plots with multiple categories and am unable to distinguish different groups. In this example I am plotting mass against SAID (Sample IDs) and number of cycles. I would like to separate the SAIDs to help visualize the samples separately. Is there a way to do this without changing the width of the bars or the spacing between cycles? Thanks for your help.

Re: Adjusting spacing between figure categoriesI suggest that you use your SAID column as an X Grouping variable and your PCR Cycles as the X axis variable.

You can then right click on the graph and select "Customize" and change the Bar's Width Proportion to whatever you need it to be, for each of the levels of the X Grouping
