Next, place a Card visual onto the canvas with the measure placed into the “Values” section. "You must first select a Product Category from the slicer to see the results" "", - Give me nothing when Check Filtered returns True , - Check Filtered returns True or False based on selection in slicer ![]() To achieve this, we need a measure that will return nothing if the selection condition has been met, and display the message when it hasn’t. The message will be displayed by default, but when the user selects an item in the Product slicer, the message will disappear and will reveal the hidden visual. Next we will create a measure that will display or hide a message to the user on the card. Note: We’ll return to this measure at the end of the article to see what other options we have here. ISFILTERED(Products) - Returns True when Any selection is made on the Category slicer We’ll start with a simple measure that will return True whenever any selection is made in the slicer. The first measure that is needed is one that can return a True or False response based on the selection in our slicer. The Card is perfect for this.īefore we can proceed with building our background switching card we need some measures. ![]() The trick then lies in having a box that can switch its background between a colour white or transparent. So while #FFFFFF is white, #FFFFFF00 is 100% transparent (white). But as it turns out, you can change the transparency of a HEX colour like #FFFFFF by adding an optional additional 2 characters to the end (00 being 100% transparent). As described in the article about conditional based text colours linked above, you can set the result of a measure as being any HEX colour you want using conditional colour formatting. The key to this solution is the expression based formatting of colours using DAX. As a result, I decided to create a Walkthrough video to assist with the implementation of this strategy. Since adding the additional measures to the method, that allow the hidden visual to still be interactive after being revealed, significantly more questions surrounding implementation challenges have emerged. If there is nothing selected in the slicer, I don’t want to see the matrix at all, but instead see some instructions on what to do. In the sample report below, I want the matrix on the left to appear if the user selects an item in the category slicer on the right. Please note, this solution works well for most standard visuals, but the Waterfall chart, Scatter plot, and Map does not deliver the same effect due to the way these visuals are rendered. Write a measure that returns either the background colour or “transparent” based on the user selection (type Text), and set that to conditionally format the background colour of the card.Write a measure to render the visual blank when nothing is selected (type Whole Number).Write a measure to display a user message on the card based on the user selection (type Text).Write a measure to check if there is a filter on the desired column (type Boolean).Create a card to work as a mask for the visual. ![]() The solution to solve this problem (when trying to Show or Hide a Power BI Visual Based on Selection) involves: If you would like the Power BI development team to include this feature in their plans, be sure to vote for the idea. ![]() Microsoft is already working on further establishing expression based formatting across the breadth of Power BI, and currently allows one to change a number of settings ranging from the header in a chart to font colours, backgrounds and data colours. If you want the user to be able to interact with a report and see (or not see) a chart based on some valid selection across the report, for the moment, this article is the best solution available. It is possible to use bookmarks to show and hide an object, but the user must click a specific button to do this. The challenge of selectively showing report elements has plagued Power BI report developers for many years now, but there is no out of the box solution for this problem at this point in time. Since that time, the article has become the most in-demand solution encountered on our website, and hence deserved a redeux. Matt has written a few articles in the past that toy with the ideas of changing visibility and text colour based on selection, and this article was first penned by his hand in April 2019, as he started to wonder if it was possible to make a power bi visual appear (or not) based on a selection from the user. This is the 3rd iteration of this Power BI Visual Based on Selection article, attempting to address some of the confusion that has emerged since I added the measure into the mix in January 2020.
