Tutorial Processes

Setting a positive value

Some operators need to know an attributes's positive value to function correctly. This example shows you how to set the positive value of one or more attributes . Click on the Set Positive Value operator to show its parameters. Then click on the Select positive values button to open a dialog. Here you can select one or more attributes and assign positive values to them. In this example we have selected the data set's label attribute 'Play' and assigned the positive value 'yes' to it.
