Changing the dimensions of the diagrams may have some unexpected consequences.
Note that a large swatch size makes a diagram slower to render. On slow devices like tablets and phones that might give the impression that links to pages with a large swatch size don’t work at all or block the device. So create links with patch sizes just large enough to recognize the pattern, visitors can easily increment the size.
When you specify a swatch that is too small, (or a link with no dimensions) the size will be automatically increased to contain at least one tile.
Right foot sides
When a diagram has a foot side on the right, it will usually match only for every so many columns. You may have to reassign the stitches.
If you want another number, go to the “Pattern definition” section: rotating the rows in the right field might help but you might need more changes. For example for this pattern you would have to change as shown below when switching between an odd and even number of spider columns. Other widths will match with neither of the variations.
