# 18. Variables Analysts are often faced with the challenging task of navigating large datasets that span across multiple dimension categories and time frames - this is where Inforiver variables can save the day. Variables offer a range of options to efficiently traverse your datasets, apply filters, and even run ad-hoc scripts. Variables are graphical controls like buttons, checkboxes, or steppers that can accept user input to perform actions like setting a filter or changing the layout. See how variables can make report navigation and editing easier without creating Inforiver filters or manually editing the header or visual measures.

Let's take a deep dive into Inforiver variables. ## 1. Creating variables **STEP 1:** You can create variable controls in your reports by clicking the **Variables** button in the **Insert** ribbon.

**STEP 2:** Click the **Add Variable** button in the **Define Variables** window. You'll need to specify the * **Label**: Set a name to identify the variable. * **Type**: Choose the type of variable: numeric, options, text, button, boolean, date range, etc. * **Value**: Set a default value for the variable.

**STEP 3:** Click the edit

icon to customize the variable. We'll cover the various options in detail in subsequent sections.

**STEP 4:** You can display variables in a side panel. Check the **Include in Variables Panel** option if you want to expose the variable in the Variables panel. You can also provide a description of the variable's function.

Variable names are automatically displayed by default in the writeback matrix visual when a variable is defined. The **Show Label in Variables panel** is auto-checked when a variable is defined. You can uncheck this option while defining a variable to hide the label name.

After you create variables, the variables side pane is displayed from where users can input values for calculations, apply filters, and trigger scripts.

## 2. Referencing variables in functions You can create a calculated measure that references the value set in a variable. Each variable has a **Technical Name** that can be referenced in formulas.

In this example, the calculated measure, Tax will change based on the toggle variable.
