If you're using Power BI to create reports and dashboards, you may have heard of DAX (Data Analysis Expressions). DAX is a powerful formula language that can help you create custom calculations and measures to gain valuable insights into your data.
ALLNOBLANKROW: This function returns all the rows in a table, except for any rows that contain blank values in all columns. This can be useful when you want to filter out irrelevant or incomplete data from your report.
GENERATESERIES: With this function, you can generate a table of values that start at a specified value and end at another specified value, incrementing by a specified step. This can be useful when you want to create a custom timeline or chart axis.
COMBINEVALUES: This function allows you to combine two or more columns into a single column with a specified delimiter. This can be useful when you want to consolidate data from multiple columns into a single field.
USERELATIONSHIP: Sometimes, you may need to create an explicit relationship between tables in Power BI, overriding any existing relationships.
ADDCOLUMNS: This function allows you to add a new calculated column to a table, based on a DAX e
xpression. This can be useful when you want to create a custom calculation that is not available in the source data.
DISTINCTCOUNTNOBLANK: This function returns a count of distinct values in a column, excluding any blank values. This can be useful when you want to analyze unique values in your data without including empty or null values.
DATESBETWEEN: With this function, you can return a table of dates between two specified dates. This can be useful when you want to create a custom date range for your report.
By leveraging these and other DAX functions, you can create custom calculations and measures that provide valuable insights into your data. Whether you're a business analyst, data s
cientist, or IT professional, DAX can help you take your Power BI reports to the next level.
