Dash subtabs content

hi there, struggling to get this right. Based on the script below if I put ‘example-graph’ in the callback then graph will update but it propagates to all pages; if I put ’ sub-content- on the callback then graph does not propagates to other pages but it does not refresh. I can I add content to subtags while managing mulitple call back ? many thks
