Understanding Visio Data Graphic’s Color by Value

The desktop Visio editions, Visio Professional and Visio Plan 2, have a great way of automatically displaying data as Data Bars, Icon Sets, Text Callouts and Color by Value. The first three types of Data Graphics require sub-shapes to be inserted into each shape that they are applied to, but the last one, Color by Value (CBV), merely requires some User-defined Cells and formulas. However, unlike the first three, there can be only one Shape Data value displayed as colours in each Data Graphic (DG). So, how can we easily update the colour assigned to each value using code, rather than manually using the manual dialogs provided?

Linking Data to Visio Shapes in Code

One of the most useful capabilities of Visio Professional and Visio Plan 2 is to link external data to shapes and have them refreshed by changes in the data source. So, many of my solutions involve writing code to make these links, and they are covered with some VBA examples in my book, Mastering Data Visualization with Microsoft Visio Professional 2016, but I mostly write C# code in VSTO add-ins, so I thought it would be useful to demonstrate how easy it is to create data links by dropping a shape, and by adding links to an existing shape. The book, by the way, is still relevant for the current Visio Professional and Visio Plan 2 editions!

Keeping Visio Data Graphic Items Level

My good friend Scott Helmers, Visio author and trainer, of Harvard Computing Group , recently asked for some help in keeping data graphic items level when their target shape is rotated. Fortunately, I was able to assist, so I thought I would explain how this can be done, and also update my Icon Maker macro from a few years ago. The updated macro is available to download for free and includes the extra ability of sizing the icons. I chose to use some bee stickers from the Insert / Illustrations / Icons tool in Visio Plan 2, and the Status options from the Process shape in the Basic Flowchart Shapes stencil to demonstrate.

Duplicating Visio Data Graphics

I was recently asked about switching between different Visio Data Graphics within a page, so I thought I should record a few short videos to explain how Visio Data Graphics work, how they can be edited and duplicated, and how to automate switching between them.

Visio 2010 MVP Session videos reprise

Back in 2012, my fellow Visio MVPs, Scott Helmers and Chris Roth, and I recorded a series of 24 videos about Visio 2010. They were first hosted on Microsoft’s web site, then they put them up on YouTube, they they got deleted :-(. Well, we have managed to retrieve them, and put them back up on YouTube in a new list :-). Most of them are still very relevant and useful!

Displaying Visio Number Shapes data clearly

Visio has had a Number Shapes add-on for many years, even since before Microsoft bought the application in 2000. The add-on autmatically creates three Shape Data rows to hold the number, any prefix text, and a value to indicate whether the shape number text should be shown. It is useful, but it can also be very annoying if you also want to label your shapes, such as with process flow shapes, or you want the shape number to be displayed outside of the main shape. Fortunately, there is a solution….
