New columns not displaying?

When adding data into the dashboard from either a spreadsheet, text file or ODBC data source, the data must be in one of the following data types listed below. If the data is not in one of the following types, it shall be rejected by the dashboard. This may lead to the datafeed either not displaying any data or the column not being usable in its current state.

• String - used to store characters or sentences in the dashboard.
• Integer - used to store whole numbers in the dashboard (1, 2, 3, etc).
• Decimal - used to store decimal point numbers in the dashboard (1.1, 1.2, 3.2, etc).
