Creating Hierarchies

This option can be used if the acquired dataset contains data that can be converted to hierarchies like Time hierarchy or Region hierarchy.

Hierarchies are used to display data at different granularity level and you can drill up/down at different levels for better understanding of relationship between objects.

Creating a Geography hierarchy

When the data is acquired, the application looks for dimension containing location and present with an icon.

Step 1 − Click the icon in front of a dimension. From the available options, select Create a Geographic hierarchy → By Names (this option is available only for string dimensions).

Step 2 − A new window will open with the name Geographical data → select the dimension to map to hierarchy. Click Confirm.

Example −

Step 3 − If Region does not apply to the dataset, select None from the list.

Step 4 − It will show you, a list of all the analyzed values, Solved and Not Found. For all the solved values, it will create a hierarchy. Click Done.

You will observe the following −

• Locations mapped exactly are marked with green.

• Locations with more than one possible match (for example, if more than one city named London was found) are marked with yellow.

• Locations not found in the geographic database are marked with Red.

• Hierarchy will be added under Geographical data.

Step 5 − To use this chart, select any Geo chart like Geo Bubble chart.

Step 6 − Add Country to Geography and Measure to the chart. Select the value in the chart and you will get a drill option to the next level.

Step7 − If you click the Drill option, you will go to the next level and so on.

In a similar way, you can apply Time hierarchy.

Creating a Custom Hierarchy

You can create hierarchies using any available combination of dimensions in acquired dataset.

Example

Category → Product Line → Product

Follow the steps given below −

Step 1 − Select Category → Options → Create a Custom hierarchy

Step 2 − A new window will open. Enter the name of the hierarchy and select the other dimensions to add to the next levels. Click Create. The arrows can be used to change the level.

Step 3 − The Product hierarchy will be added under the Dimensions tab.

Step 4 − Add a Bar chart and then Add Category and QTY to measures.

Once you click the Category option, you will get an option to drill down to the next level (PROD).
