Help with Excel finale project! I do not have excel on my computer( Google Chromebook).

Hey there,

I am using a google chrome book and I do not have excel on it. I am using office online. It will not allow me to use a 3D chart only 2D. I am also not able to hold down control to select multiple cells-to insert into the chart. I currently can not afford a new computer or to purchase "office/excel". Can any one give me any advise on how to complete this project.

Thanks,

Kayelyn
