Optimize Visio Flowcharts: Swimlane Reordering Tips

Microsoft Visio desktop Plan 2 and Professional editions provides the ability to create and synchronize cross-functional flowcharts between the diagram and an Excel table. This is great, and widely used for many types of processes. The Excel table normally has a Function / Swimlane column that contains text that becomes labels on the swimlane containers, and a Phase / Timeline column that contains text that becomes the label of the phase or separator containers. The import provides the option to order the diagram by Function and/or Phase, but it is impossible to get them ordered by both! This article provides a solution using a free macro-enabled Visio stencil.

Linking Data to Shapes in Visio after using Data Visualizer

Data Visualizer (DV) in Visio Plan 2 (Data | Create from Data | Create ) is great because it provides a way of automatically creating a diagram from data, but it also prevents some of the other data-linking features in Visio from being used. This is because DV wants to take control of the data in the shapes to provide refreshes from the data source or send updates to the data source. This can be very annoying if you use DV to create the initial layout, then you enhance this, so it looks just perfect, and then you just want to update some of the data without affecting the layout. DV may re-layout your carefully crafted diagram, even if there are no updates to the data that should do that. Also, you may want to integrate data from other sources that were not available or accessible to the table or query used for by Data Visualizer. This is when you may want to use Data | External Data | Custom Import which also provides a much greater number of data source types. In this article, you will learn how you can do this manually, or automate it with the help of a little VBA code (or similar).

In this example, I have used table of personnel that I have used before, but added an extra column, Shape Type, that simply has the value Rectangle, which is simply the name of a simple Master shape that I have added to my macro-enabled stencil, ExDataLinker.vssm.

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:

Pushing Data Visualizer in Visio to the limits!

Regular readers of my blog will know that I like to use the Data Visualizer (DV) in Visio Plan 2, but I recently tried to help a user who really decided to push it to the limits. In this scenario, there were multiple connections, but with different labels, being created between the same flowchart shapes, and the plea was how to make it work! Well, I experimented with this, and found that DV does not really work well in this way, and then proposed an alternative approach, which I will explain in this article.

First, I will show how it fails by setting up an Excel table that does contains multiple connections, but fails to update the labels consistently.

Binding Visio and Excel with Data Visualizer

I re-vamped some of my content about the Visio Data Visualizer add-in for Excel in my last post, so I thought I should expand a bit more on the Data Visualizer feature in Visio for Desktop (Visio Plan 2) and Excel for Desktop. I have described it in detail in previous posts, but I never published the process diagram I created for the Data Visualizer Wizard in Visio. So, I thought I would use it to demonstrate a few cool features of Visio for Desktop.

Editing Visio Data Visualizer in Excel

I have previously described how to use the Visio Data Visualizer add-in in Excel, but I didn’t make it clear how you can edit the diagram created if you have a Visio license. So, I have recorded three short videos to briefly explain this.
