In my last post I showed lots of examples of how Power BI’s new custom format string feature can be used to format numbers. This post, looking at dates and times, will be a bit different for two reasons: there are a lot more useful examples of custom date and time formats built into Power BI Desktop, and some of the format placeholders listed in the VBA documentation aren’t supported in Power BI.
Now that we can apply custom format strings to fields and measures in Power BI in the September 2019 release, I thought it would be useful to provide some examples of what’s possible with this very flexible new feature because the existing documentation for VBA isn’t easy to make sense of. In fact there’s so much to say I’m going to have to write a series of blog posts to cover everything! In this first post I’m going to look at formatting numbers.
Following on from my last two posts on Power Query performance, I thought I would write about another trick that can make a big difference to your query execution times. It’s actually something that Ehren from the dev team mentioned in a forums thread that I blogged about here but it deserves to be better known.
A few years ago I blogged about the Table.Profile M function and how you could use it to create a table of descriptive statistics for your data:
Since that post was written a new, optional second parameter has been added to the function called additionalAggregates which allows you to add your own custom columns containing aggregate values to the output of Table.Profile, so I thought I’d write a follow-up on how to use it.
With data clearly taking the position as king in today’s business world, it’s important to have a tool that can help you tame it and use it to your advantage. Microsoft is all about helping you create a “data culture” in your organization—in other words, taking advantage of data across the organization to tackle any problem and meet any goal. Microsoft Power BI does just that…but what about other tools? Yes, there are other options, but there are so many benefits offered by Power BI that we believe it’s clearly the best choice. Here are 5 reasons why we love Power BI:
If you’ve ever built a BI solution it’s likely you will have had to integrate third party data, and if that’s the case you will know how painful it often is to get your hands on that data. Badly designed portals you have to log into every week to download the data, CSV files emailed to you, APIs with complex authentication – it’s usually an unreliable, slow and manual process.
The problem of blank values being shown in a Power BI slicer is fairly well known, but did you know that in some circumstances slicers can show other values that you would not expect to see? While there’s a good reason for this it can nevertheless be mildly confusing for developers and end users alike when it happens.
