I need help customizing my chart in my wordpress website.
I really know nothing about putting shortcodes together or how to customize different items.
Situation:
I am using the wordpress plugin 'Inline Google Spreadsheet viewer' and do not know how to edit different aspects of my table. My chart looks like that below attached image.

How do I go about doing all this and where to put the shortcodes/html codes?
(I also have two charts on my and would like them to match aside from the number of rows.)
This is all i see in my wordpress dashboard:
