A Sheet holds all data from an uploaded spreadsheet file along with the charts created to showcase this data.
A list of all of your Sheets can be viewed from the dashboard. Double click on a sheet to open it. Sheets can also be deleted and renamed from the dashboard via the row menu.
Add a new Sheet by clicking the Add New Sheet button, or drag a spreadsheet file from your local file system to the dashboard.
A Sheet can have multiple charts. Each chart has its own set of filters applied to the Sheet data. This makes it possible to show off different sets of data, while sharing the same underlying data set.
The same data is shared between all charts in a sheet. If the data is edited, this edit will apply to all charts.
