Adding a diagram
A diagram is similar to a map visualization. You use it to display spatial information in the form of shape, path, and symbol elements.
Then you assign data to these elements so that their appearance (such as color) will change based on data values.

2. Supported formats
The diagram visualization supports the SVG (Scalable Vector Graphics) format. Many tools can produce SVG diagrams, including Microsoft Visio.
An example SVG file looks like this:
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" version="1.1" height="100%" width="100%" viewBox="0 0 200 200"> <defs> <clipPath id="def_fLQzAQ==_1"> <path d="M20,112A12,12,0,0,1,8,100A92,92,0,0,1,192,100A12,12,0,0,1,180,112L116.970562748477,116.970562748477A24,24,0,0,1,83.0294372515229,116.970562748477z"/> </clipPath> ...
An example XAML file looks like this:
<Canvas xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Name="floorplan" Width="800" Height="600" Clip="F1 M 0,0L 800,0L 800,600L 0,600L 0,0"> <Canvas x:Name="Layer_1" Width="800" Height="600" Canvas.Left="0" Canvas.Top="0"> <Path x:Name="Path" Width="457.932" Height="461.235" Canvas.Left="72.4715" Canvas.Top="93.5018" Stretch="Fill" StrokeLineJoin="Round" Stroke="#FF000000" Data="F1 M 529.904,141.916L 481.918,94.0018L 120.078,94.0019L 72.9715,141.108C 72.9715,141.108 72.9715,499.975 72.9715,506.173C 72.9715,512.371 121.036,554.237 121.036,554.237L 486.085,554.237L 529.725,510.598L 529.904,141.916 Z "/> <Rectangle x:Name="Rectangle" Width="17" Height="17" Canvas.Left="115" Canvas.Top="125" Stretch="Fill" Fill="#FF000000"/> <Rectangle x:Name="Rectangle_0" Width="17" Height="17" Canvas.Left="139" Canvas.Top="125" Stretch="Fill" Fill="#FFFF0000"/> ...
3. Displaying a diagram
For this example, create a new dashboard from the main menu, and use the blank dashboard template.
Locate your diagram file in Windows Explorer or Finder.
Drag the file and drop it over the Explore window in Dundas BI.
The diagram file is imported into Dundas BI under the Diagrams folder in the Explore window.
3.2. Drag the diagram to the canvas
When editing a dashboard or other view, drag a diagram from the Diagrams folder to the dashboard canvas.
A diagram visualization appears on the canvas.
When editing a metric set full-screen, re-visualize your data to a Diagram before dragging the diagram from the Explore window.
You can go to the Properties window and change appearance settings for the diagram.
4. Add data to the diagram
When data is added to a diagram or re-visualized to a diagram, it is connected automatically to the names from one of the hierarchies you selected. A measure is assigned automatically to change the colours of diagram elements based on the values.
To change which hierarchy or measure is assigned to the diagram and where, go to the Data Analysis Panel, click Visualization, add or remove data from the visualization options.
Colors and sizes are determined using color rules and size rules, which you can configure via the Properties window.
For example, select the diagram, go to Properties window, and modify the shape color rule in order to change the colors of the shapes in the diagram.
Symbols can also be placed according to the coordinates from your data source if they correspond with the coordinates used in the diagram, the same way symbols can be plotted on maps with latitude and longitude coordinates. Paths can be set up to connect between pairs of symbol names that come from your data source.
For more details on changing colors and sizes of diagram elements based on data, or plotting symbols and paths from your data source, see Displaying symbols on a map.
5. Compatible names
In case the data you want to use has column values that cannot be matched against the names of elements from the file, Dundas BI will attempt to use alternate names. Uploaded diagrams will use groups and custom properties from the diagram file as sources of alternate names.
If the data does not match the names or the alternate names, you can manually set the Shape Compatible Name property for the shape element.
Path and symbol elements also have compatible name properties.
6. Using a diagram
Once your design is complete, go to the toolbar and click View.
In View mode, you can:
- Zoom in or zoom out on the diagram by using the mouse wheel.
- Pan across the diagram by clicking and dragging it in any direction.
- Hover over a shape on the diagram to view its corresponding tooltip (which shows the connected data values).
Note that zoom or pan changes that you make in View mode will persist even when you switch back to Edit mode.
