The importance of #layers in Visio for Power BI

Judging by the number of downloads of my free Visio and Power BI GuIde, there is an increasing recognition of this great feature. I recently started to prepare an example for someone, but found that their sample Visio document has just over the 1,000 shape limit, so what can you do about that? The answer is to modify the master shapes so only the top level of the group has a # symbol at the start. This ensures that only the shapes on these layers are counted. In this particular example the count of shapes was reduced from 1,084 to 278 … well within the limit!

So, how is this done? Well, this can be done manually by editing each master shape. In this following example the shape count is reduced from 6 to 1 using this method, and there are 45 instances of this master shape on the page. so that makes 45*5=225 less shapes just by editing this one master.

  • Master structure with # layer for the top level group

How to migrate from Lucidchart to Visio

I am pleased to announce that I will be presenting a webinar on Thursday 10th October 2024 where I will be demonstrating how to convert many types of diagrams from Lucidchart to Visio, and keep their smartness. Over the 30 years that I have been using and developing solutions with Visio, I have seen many imitators come and go. Lucidchart, however, has carved out a niche over the years because it is available on Macs, whereas Visio only relatively recently became available in the web browser. Now that Microsoft provide a version of Visio as part of Microsoft 365, and more capable web versions for a subscription that is less than the equivalent Lucidchart cost. Moreover, Microsoft Visio Plan 2 has the ever popular Windows desktop edition that has many more features and can be used as a design studio for diagrams to be used in the web editions.

The following examples are conversions from Lucidchart to Visio Plan 1.

  • Org Chart
  • Configuration Management
  • Cluster Chart
  • AWS Web Application
  • Flow Chart

Setting Default Measurement Units in Visio Pages

Microsoft Visio can handle many different units of measurements which can be set for a page and separately for shapes, such as dimensions, within the page. This can confuse some users who expect them both to be the same all the time. In fact, the dimension units can be set to be the same as the page units, but not necessarily so. It is possible to have different units on different dimension shapes, but is also possible to set all the same with one click, and to synchronise them with the page units.

  • Page Units
  • Dimension Units
  • Page Scale

Refreshing the cached installed files of Visio

I have created many Visio solutions over the past 25 years and used a number of methods of creating an installation that includes Visio templates and stencils. I have just wasted many hours trying to debug an installation created with Advanced Installer until I realised that the problem was that Visio was not properly updating the cache of installed templates and stencils. In the end, the answer was to delete the cache and let Visio re-create it. The screenshots below show the custom shapes opened with the custom template and the More Shapes context menu. Before I deleted the cache, Visio incorrectly displayed the file name of some of the stencils (those with a trailing “_M” ) rather than the display name as entered into the PublishComponent table in Advanced Installer. In addition, the context menu did not show those stencils as being present in the workspace.

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.

Synchronizing Visio Shape Fill Color (or almost any cell) across pages

I was recently asked how the color of one shape can be changed and for other shapes to be automatically updated to the same color … even if they are on different pages! Well, it is possible with Microsoft Visio’s awesome ShapeSheet formulas. In fact, this capability is not limited to the FillForegnd cell … check out the Microsoft Learn page about SETATREF(…), and view the video below to find out more.
