Charts Creator

It took me 2 hours to make a chart and I accidentally left it and it didn’t save and I didn’t get it back

I need 2 pie charts but I make one and it is gone😠

Yes

I though this app would be great for making multiple fun charts. But when I was making lots groups to track my food like, fruit grains, dairy... but when I wanted to make another chart I clicked the back button and when I came back to my first original chart that I had made had been deleted. So I recreated it then I hit back again, then when I came came back it was deleted I did this three more times and I tried every thing and I just couldn't save my chart! I tried all the different charts and they all got deleted. I want to know a way that I can keep my charts. And a way I can create the colors on my chart. Lastly a way I can make multiple charts of the same type.
