Join Chris Dutton for an in-depth discussion in this video Data validation, part of Building a Dynamic Heat Map in Excel.
- Okay, so at this point our heat map…incorporates all of the data in our sample.…But, what if we want to allow the user to…filter the view to only show a certain type of accident?…So, what if we want to see the difference…between auto accidents, and pedestrian accidents…and bicycle accidents?…We're going to do that by creating…a drop-down filter using an Excel tool…called data validation.…Data validation allows you to specify exactly…what values a particular cell can take.…
And, when you use data validation…just a heads up that once you have a rule in place,…deleting the content of a cell will not remove…any existing validation rules.…You need to revert the data validation…settings back to allow the cell to…once again take any value.…So there are a number of different data validation options.…For example, you can allow a cell to only take…whole numbers between one and 10,…only values from within a specific list,…only text longer than a specified number of characters.…
There are really a number of different options here.…
Chris Dutton provides hands-on examples designed to showcase why certain functions—DATEVALUE, VLOOKUP, COUNTIF, and more—are so valuable to mapping data. He also shows how to use conditional color-scale formatting to map your data matrix, and find different ways to examine the same data with different criteria, using dynamic filters. The course wraps up with a few finishing touches to make your heat map even more useful and engaging, including a preview of what's possible with the Power Map addin.
