Pushing Data Visualizer in Visio beyond its limits

My last post was about some of the lessons learnt when trying to push Data Visualizer to its limits, but this one has some ways of overcoming these limitations. The main lesson learnt is that DV binds the shapes within the DV container shape, CFF Data Visualizer, and controls some of the ShapeSheet cells that are normally available for customization. The label of the connector is bound to the respective column in the Excel table, and that, combined with the ability to modify the Dynamic connector master shape provides a way of overcoming some of the limitations discovered.

So, given that we want to use DV, and we need to have multiple flows between the same shapes, then they cannot be separate connectors. We need to combine multiple flows onto the same connector, and then find a way to selectively display different flows somehow by controlling the visibility of the connectors. However, we cannot make them invisible because they will be deleted by DV, so we need to control their transparency instead. We can do this by interpreting the label somehow, and we are going to modify the Dynamic connector to react to the text of the label, and we can also change the colour and line pattern too.

The following screenshots show the Excel table with the multiple flows between the same shapes concatenated with pipe characters, and the diagram created by Data Visualizer when this table is imported into a custom template using Data \ Create from Data \ Create:

A Visio List Shape is also a Container

Structured diagrams have been around in Microsoft Visio since 2010 and I have always known that list shapes are a specialized container shape, however it still came as a surprise to me recently that a list shape can simultaneously act as a container shape!

There are a few examples of both container and list shapes in the Microsoft provided content in all versions of Visio desktop, and even in the subscription Visio for web. The most popular of these is the Cross-Functional Flowchart template which contains container shapes (the Swimlane and Separator shapes) within list shapes (Swimlane List and Phase List), which are within another container shape (CFF Container).

In Visio desktop, the Insert / Diagram Parts / Container allows you to choose from a number of pre-built container shapes. There is no button to insert a list shape, but you can create your own or easily modify one of the pre-built ones to behave as a list shape.

Taking Visio Actions Rows to the limit

I recently (re-)discovered that there is a limit to the number of Actions section rows that will be evaluated for display on the right mouse menu of a Visio shape. I have not hit a limit (yet) for the number of rows that can be added to the Actions section … so why is there a limitation to the number that will be displayed on the right mouse menu? In Visio for desktop, any rows over this limit will simply not be displayed, but in Visio for web it prevents any Actions from being displayed at all on the shape.

  • Visio for desktop evaluates the first 50 Actions
  • Visio for web can only display 49 Actions

Update any Visio ShapeSheet cell with External Data

When Microsoft introduced a new way of linking external data to Visio shapes in 2007, I initially bemoaned the inability to update anything but Shape Data row values, unlike the old database add-on that I had been using for 10 years. The new method, though, has many advantages over the old way, not least that it is part of the Visio code library, for any Visio desktop user except the Standard edition.

The smartness of Visio shapes is derived from the formulas in the ShapeSheet that lies behind everything. There is a developer interface into this ShapeSheet in every desktop edition, but there is none in any of the web editions, even though the formulas, for the most part, work perfectly well (see my series of posts ShapeSheet Functions A-Z ).

The newer methodology of linking Visio shapes to data can also be used to refresh Visio diagrams automatically, even if the Visio document is not opened in the desktop edition. The Visio documents merely need to be stored in OneDrive, SharePoint (or Teams). This makes it suitable for solution development without assuming that every consumer has a desktop license. Indeed, the Visio Data Visualizer utilizes these newer external data recordsets embedded within the Visio document.

For my example, I used the Visio Sample Database that has been installed with Visio since 1997 for demonstrating the old database linking technology. It is an old style Access database (mdb), and can be found in a sub-folder of the Visio installation folder. I simply used the Data \ External Data \ Custom Import command to import the Bolts – Square Head table.

Referencing Container Data in Visio

Microsoft Visio has a useful Structured Diagramming concept that consists of Containers, Callouts and Connectors. The first of these features make it possible for shapes to know what they are contained within, as a better option to grouping shapes together. Grouping can hide or break the grouped shapes smartness, so Visio provides two ways of allowing shapes to be members of one or more containers. There are a few built-in Container shapes that can be added with the Insert / Diagram Parts / Container gallery, but shape developers can also create their own. Member shapes can be positioned anywhere within the container. There is a second type of container, List, that provides the ability to have ordered member items. There is no ribbon command to add these, but there are a number of these special shapes provided in the OOTB Visio stencils. For example, dragging and dropping a List box shape from the Software and Database / Software / Controls stencil will automatically add three List box item shapes to it.
