2. Treemap Visualization in Qlik Sense

The treemap visualization has got its name from the fact that data is referred to and handled as tree parts i.e. branches, nodes, leaves. It is used to display hierarchical data i.e. data that is present in many layers of logic. The hierarchical data is represented in nested rectangles or boxes i.e. small boxes within large boxes.

Let us understand this with the help of an example, suppose we want to analyze sales of an online shopping site. The data of such a site will be hierarchical that is, there will be many groups like electronics, clothing, home & kitchen, health & beauty, sports, automobiles, entertainment etc. These categories will become the branches of a treemap chart and the sub-categories within these categories like mobile phones, TV, laptops, tablets, cameras, stereo systems etc. will be the leaves of the branch, electronics.

Notice in the image of a treemap chart given below.

Branches in Treemap

This treemap has seven branches shown in the bigger boxes titled, Food, Beverages & Tobacco, Home & Garden, Health & Beauty, Hardware, etc. Each of these boxes further has smaller boxes i.e. leaves of the branches namely, Frozen vegetables, Cereals, Power equipment, face pack etc. We can divide or drill down these leaves into smaller boxes having sub-sub category entries. The color and size of each box are in proportion with the quantity of that has been sold. More the sold quantity, darker the color, and bigger the box. You can set the color and size gradation from the properties panel in three ways, by dimension, by the expression, and by measure. In the sections to follow, we will learn how to create a treemap visualization and configure it accordingly using the properties panel.

3. When to Use a Treemap Visualization?

A treemap is the best choice to make when you have loads of hierarchical data and not that much space on the sheet. Treemaps save a lot of space on the sheet as it can contain as many data values as it can in the form of small to smallest boxes (nested rectangles). The color scheming and size grading reveals the highs and lows of the situation and tells you at an instant which product is doing good and which needs more attention and strategy. The one major drawback of a treemap chart is that it does not show negative values.

4. How to Create Treemap Visualization in Qlik Sense?

As you can see, the treemap created here is a simple one having leaves that show product quantity of each product specified on the smaller boxes/leaves. The color grading is in play here as well, where the color is getting lighter and the box size is getting lighter as the quantity of the product decreases.

5. Properties Panel in Treemap in Qlik Sense

The properties or exploration panel appear at the left of the editor and consist of three sections that we will discuss below.

a. Data

From this section, you can add dimensions and measure fields. You can add expressions and labels to individual dimensions and measures. You can add as many dimensions (rationally possible) as you require. Alternative dimensions and measures can also be added.
