Calculations

Calculations are math formulas that calculate new data series from other series.

A calculation in dataZoa works just like a cell in a spreadsheet, only applied to an entire time-series in one shot!

Your calculations are stored in your account and evaluated in the dataZoa ComputeCloud.

Common Features

All dataZoa calculations share some common features:

• Live - automatically updated whenever underlying data or calculations change

Creating

From the dropZone

From the dropZone, open the Gear menu, check Pick individual series, select your input series, then pop open Make a ComputeCloud Formula. See illustrations here.

From the Workbench

From the Workbench, checkbox the series you want to include, then click the + button in the header to pop open the formula editor.

This will bring up the appropriate display editor and give you an immediate preview of your new display. Once you give it a name and save it, it will be added to your list of displays of that type.

If you want to build several calculations from the same general group of data, consider using the dZCorkboard.

To edit an existing calculation, use the dropZone or Workbench.

Your calculated series are marked with a blue formula flask. When you hover on the series and click on its flask

you get a menu with several calculation options. The first one opens the formula editor with the formula and setting for the calculation being edited.

Inputs Section

The Series you checked are the inputs to your Formula:

Formula Section

Use V1, V2, etc. as your formula variables:

By their very nature, Formulas are an open-ended topic. These are excellent points of departure:

• The dataZoa ComputeCloud Reference documents all of the intrinsic functions and arguments that can be used in Formulas. Download it here.
• Nothing teaches quite like examples. See some ComputeCloud Formula Examples here.

Buttons Section

Use these buttons to test and finally save your Formula:

Options (Advanced)

These options are used to override the natural default behaviors for NA handling and the padding/trimming of series that do not start and end at the same point in time.

• NA Handling
• Missing_Values
