 What is the parameter in power bi ?

A parameter in Power BI can refer to two different things:

1. Query parameters: These are values used to control how data is retrieved from a data source in Power Query. They allow you to dynamically change the output of your queries depending on the parameter value. For example, you could have a parameter that specifies the date range to be included in the query, or a parameter that selects which columns to retrieve.

2. Visual parameters: These are values used to control how data is displayed in a Power BI visualization. They allow users to interact with the visualization and see different subsets of the data. For example, you could have a parameter that filters the data by a specific region, or a parameter that changes the color of a chart.

Here's a table summarizing the differences between query parameters and visual parameters:

Feature	Query Parameter	Visual Parameter
Purpose	Controls how data is retrieved from a data source	Controls how data is displayed in a visualization
Location	Defined in the Power Query Editor	Defined in the Formatting pane of a visualization
Scope	Affects the entire dataset for a report	Affects only the specific visualization where it is used
User interaction	Not available to users of the report	Can be used by users of the report to interact with the visualization

I hope this helps! Let me know if you have any other questions.
