Visualize Your Dataset is the third of the 5 part series – SAP Lumira for Beginners.
A primary goal of data visualization is to communicate information clearly and efficiently via statistical graphics, plots and information graphics. – Wikipedia
Once the majority of the data preparation is completed, we can move to the Visualize room to make effective visualizations. This is where we can find patterns, test hypothesis and figure out what your data mean efficiently.
Lumira has a pretty easy interface to build visualizations. Most of the functionalities involve drag and drop.
1) Chart Selection :
Lumira offers a wide range of charts, maps and plots that can be accessed from the drop downs. Custom charts can also be built and installed as an extension which would be available in the Chart Builder.
There are some great articles on selecting the correct visualization and how keeping things simple will convey more information. Below is a quick summary of chart suggestions based on the kind of analysis.
For more detailed information, I would refer to blogs by Stephen Few : Visual Business Intelligence
2) Datasets in Use : This represents the datasets which are used to build the current visualization. It is very handy when we would want to link dimensions from two datasets during Data Blending.
3) Depending upon the chart type we can choose the suitable Measure(s) to be used.
4) Depending upon the chart type we can choose the suitable Dimension(s) to be used.
5) Trellis : This can be used to represent multiple dimensions across rows or columns.
6) Tooltip : A summary of the values for the portion of the chart which is selected.
7) Legend : Summary of Dimensions which are visible in the chart.
8) Filter : This would be the easiest option to add, modify or remove filter conditions.
9) Related Visualizations : Lumira is a data-discovery tool as well. This option provides a series of suggested charts with a combination of measures and dimensions that can be used for your analysis.
10) This option helps us adding new visualizations and access existing ones.
Other options that can be leveraged using the settings are,
11) Ability to export records as a Excel or CSV file.
12) Rules that can be created and managed for conditional formatting.
13) Calculations which can be done on the fly include,
14) Option to sort dimensions in ascending or descending order.
15) Option to rank based on measures.
16) Option to clear the chart.
17) Other settings include,
18) Option to maximise the view and perform analysis on a single chart.
