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, except that the "cell" contains an entire series!

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. See illustrations here.

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

Editing

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.

Tab:

Formula

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

Sharing

The result of a Calculation is a distinct Series, which can be Series like any other as you see fit.

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