Wave 105: Dashboards

How to build a dashboard? 

You start by exporting the dataset.  

When you clip a lens it goes to the left corner.  

Process of building a dashboard is to choose a widget and combine with a  dashboard and placing it.  

Certain widgets act as input and some as output.  

With a list object only one grouping lens' are compatible. 

On the right there are widget and lens properties.  

 For a number widget only the non-grouped lens' are compatible.  

Alignment of the widgets can be done by mouse of by using the arrows.  

The name of the widget can be changed from the widget properties. 

In a chart widget, you need to go to chart properties and choose the chart type icon to change a chart from bar to pie or whatever is required. 

Display legend can be used to display the legend in the chart widget. 

Widget is the visual representation of the query. The real magic happens in the lens or the snapshot which is the query. 

Majority of the data work is done at the lens level. 

Lens Properties: 

By default all filterting is by single. By changing to multi, it goes from radio button to a check box and multiple values can be selected. When multiple values are clicked the widget refreshes. To prevent this you uncheck the update box in the lens property.  

Filter by selection is a feature is when you open the dashboard and choosing a particular value and choosing this feature which would set it as a default value. 

Global filter can be applied to the whole dashboard and that is the purpose of the global scope. Click Scope and you will see the compatible lens. Since it is a global filter, the filter lens will work. Choosing a filter lens with count type would help.  

You can clip it to the designer and the new lens is created.  

So now you can now get the data based on the filter.  

Facet Concept: 

It is making change in one part of the dashboard and seeing the change reflected through the rest of the dashboard is called facets/faceting. 

Faceting changes the visualizations based on the global filter. So when we touch one part of the dashboard it transforms all the widgets on the dashboards. 

Choosing the same lens on the dashboard, you cannot have one lens as a faceted and others are not.  

UseCase: for global averages don’t facet some values to get some interesting data through. 

Issue: How to show the end user that it’s a static number and its not a glitch.  

Ideally, use some aesthetics to do it, like having a different color.  

Types of Widgets? Filter, Display and Layout 

What are layout widgets? 

Box, text box and other properties like those are called layout widgets.  

I.e. it’s a way of formatting.  

Box widgets allows changing of background color as well, border color can also be changed. You can embed images or documents as well, but it should be publicly accessible image for the org. 

Link object is a way to link to another lens or dashboard or widget.
