问题 In my PowerBI desktop, I have table that is calculated from over other tables with a structure like this: Input table: <table border="1" class="dataframe"> <thead> <tr style="text-align: right;"> <th>Firstname</th> <th>Email</th> </tr> </thead> <tbody> <tr> <td>Scott</td> <td>ABC@XYZ.com</td> </tr> <tr> <td>Bob</td> <td>ABC@XYZ.com</td> </tr> <tr> <td>Ted</td> <td>ABC@XYZ.com</td> </tr> <tr> <td>Scott</td> <td>EDF@XYZ.com</td> </tr> <tr> <td>Scott</td> <td>LMN@QRS.com</td> </tr> <tr> <td>Bill

问题 Let's say I have the following data frame. I want to calculate the average number of days between all the activities for a particular account using Dax in power bi Let say I have this: I want a desired result like this How do I achieve this using DAX in power BI 回答1: Assuming you have the data in a table as in your picture, create a calculated column like this: AvgerageDaysInbetween = var thisCustomer = [Customer] var temp = SUMX( FILTER( SUMMARIZE( 'Table'; [Customer]; "avg"; DIVIDE(

问题 When our power bi report runs it runs it for current date which is created by Relative slicer. Our user would also like to have some options to select different date ranges using an actual calendar and clicking on it after the initial report has been run using a current date filter. The way which is done in SSRS. 回答1: Use a data slicer other than List, Dropdown or Relative, all other visualizations (Between, Before, and After) provide a calendar interface when you select the date: 来源： https:/

问题 I’m trying to represent some continuous data via binning. Continuous weighting data of an area should be binned as: VeryHigh, High, Low, VeryLow. The weighting values are based on an interaction between certain Types of events grouped by an Area and so can change depending on the Type selected by the report user. I have included some sample data below and an outline of what’s been done so far. Start with five sets of area data (A-E). Within each is one or more incident Types. Each incident

问题 I created a measure using joined tables to show me a rate of something. The problem I'm having is that the rounding of my value is always 2 places. It's a very finite rate that requires at least 3 rounding places. I've tried using ROUND , but that doesn't work. I've included a screen cap of my visual and my measure. 回答1: The ROUND function does round it to 4 decimal places but what you want is to format it to show more decimal places. Select your measure and go to the Modeling table at the

问题 Let's say I have a large list of names in a single column. I want to see if the names have the letters "y" or "z" in them, with a calculated column that just tags the row as "Y" or "Z". My question is not just about searching with wildcards in DAX. My main question is whether I can create the following table: +-------+-------+ | Y | Z | +-------+-------+ | "*y*" | "*z*" | +-------+-------+ and then use the contents of that table in a DAX search (without creating any relationship). In DAX-ish

问题 I'm gathering my data from a third-party REST API which has many thousands of records but updates each day with many more and so refreshing my data sources becomes a long task. So I was wondering if there was any way to do incremental loads and only scrape the last 30 days worth of data from the API and append that to a table in PowerBI Desktop. I've looked into the append queries feature but this seems to only be able to join 2 queries and return a single table, which would eventually run

问题 Is there a way to differentiate between a blank value in a column and a 0 value in a column, when I tested with an if statement they were treated as the same value... any suggestions? 回答1: Yes, there is. In a calculated column, first test a value for being blank, then test for beign zero: So, create a flag and filter your sum measure by it, i.e, No blanks sum = CALCULATE( SUM(Table[Amount]), Test <> "Blank") 回答2: Not really. You see, the SUM function in DAX sends a SUM function to SQL, and

问题 I want to reference a table column by a variable while creating another column but I can't get the syntax: t0 = Table.FromRecords({[a = 1, b = 2]}), c0 = "a", c1 = "b", t1 = Table.AddColumn(t0, "c", each([c0] + [c1])) I get the error the record's field 'c0' was not found . It is understanding c0 as a literal but I want the text value contained in c0 . How to do it? Edit I used this inspired by the accepted answer: t0 = Table.FromRecords({[a = 1, b = 2]}), c0 = "a", c1 = "b", t1 = Table
