Figure 18.   Example algorithm

Each algorithm, typically, has at least one DataSourceBlock, which is linked to other algorithm blocks. Blocks are chained together with links from the output of one block to an input on the next block. It is easy to mis-connect an Out to an In. Make sure you connect from the Out slot, and not from another slot.

To open a block’s Property Sheet, double-click the block. TheNiagara Analytics Framework Reference and online Help system document the properties for each specific block. If you edit a property, click Save.

The UniMath and BiMath objects indicate the number of inputs. Something similar is true for the switches. You must connect all inputs required for each math block. For example, do not use a bi block if you have only one input.

To add comparison logic, drag a BiSwitch from the palette’s Switches folder. Using this block you define the Operator (Greater Than, Less Than, etc.), then connect the appropriate Out slot(s) to it.

Some blocks provide actions. Right-click the block and select the action. For example, right-clicking a constant block assumes you want to set its value.
