Step 5 - Set Class for Numeric Fields

Tutorial 1 for Pro Version: Aggregate and Visualize Your Data

Step 5 - Set “Class” for Numeric Fields

Note: If you are using SQL, skip this step. Do not change the class of your fields. With SQL, Jasper will automatically set the appropriate class for each field.

When you're importing data from a custom report, by default, all fields are read as text fields. You’ll need to tell JasperSoft Studio which fields are numeric by adjusting the “Class” setting.

• Click the Outline Tab

• Expand the “Fields” section in your Outline

• Select all your Integer fields

  • Use control-click or command-click to select multiple fields at once

  • Do not change the Student ID field

Next,

• Locate the Properties Tab

• In the Properties tab, set the appropriate “Class” of your numeric fields.

• Set Class for any Integer fields to java.lang.Integer

Repeat the process if you have any decimal numbers in your data.

• Set Class for any Decimal fields to java.lang.Double.

Class field is case sensitive.
