I have a page that contains a large, detailed graphic with multiple buttons you can click to open various hidden states of additional information. As there are so many buttons you can click, when viewed on a mobile phone, a single finger press, may inevitably be difficult for some users. It's a busy, but nessecary graphic. Ah ha, I can pinch zoom into the graphic, and view the buttons and the graphical content in much greater depth. Sorted! however now when I do click a button, the new object state that pops up, is now already zoomed into at the degree Ive used to view the original page graphic. Not great.
How can I set the new object state, to force itself back to 100% normal zoom state when being triggered?
