Change width of multiple lines in 2d line chart, all at once

Hi ivgon,

Shift click or command click to select all the lines

Then change the thickness of them all at once in Format Panel > Style tab > Connection Line

"Also, the colours repeat for different fields, which looks like a limitation of Numbers?"

Colours do repeat through a limited range, but you can recolour them individually in the Style tab.

Save as Template to use for other data.

Regards,

Ian.

You can click one line, and while holding down shift or command, click other lines to select them.

While they are all selected then set the thickness of all of them at once.

Another way to select them all is to select one then use Command A (the "select all" command) to select all the others.
