As a result, usually, in a tree map almost all the squares or nodes will appear blank. Hence, the area available to print the labels, become small. Summary: A slight disadvantage of using tree maps in Tableau is that, as the number of items increase, the amount of space allocated for each item decreases. Similarly, the greener the node, more is the profit in that state. Bigger the size of the node, greater is the sales in that state. Quick Hands- On: Show the sales and profit in all regions for different products category and Sub-Category.Īnalysis of the visualization: The profit (color) and sales (size) of products are given at a Category and Sub- Category level. In a tree map 1 or more dimensions & up to 2 measures are used to create such a map. The rectangles in the tree map range in size from the top left corner of the chart to the bottom right corner, with the largest rectangle positioned in the top left corner and the smallest rectangle in the bottom right corner.
Nested rectangles mean that hierarchy levels in the data are expressed by larger rectangles (above in the hierarchy) containing smaller ones (below in the hierarchy). The space in the view is divided into rectangles that are sized and ordered by a measure. In case of hierarchical (tree-structured) data these rectangles are nested. The ‘tree map’ is a chart type that displays hierarchical or part-to-whole relationships via rectangles. Tree maps are a relatively new feature in Tableau, first appearing in version 8.0. Hence, it is very easy to understand the performance of different products in different regions, at one glance, just by looking at the heat map. The total sales are represented by the size. Quick Hands-On: Shows the sales and profit in all regions for different products category and sub-Category.Īnalysis of visualization: The profit is represented by the color and ranges from red for loss to green for profit. In a heat map, one measure can be assigned to the color and another measure can be assigned to the size. In heat map, you can quickly see a wide array of information. The layout is similar to a text table with variations in values encoded as colors.
It helps to visualize measures against dimensions with the help of colors and size to compare one or more dimensions & up to two measures. Heat map is a type of visualization tool that is very apt to compare different categories. We the faculty at Dexlab Analytics, the premiere Tableau Training Institute in Gurgaon aim to clarify this common doubt with this brief discussion on these two maps. This article will help to draw a clear line between heat maps and tree maps, thus enabling analysts pursuing tableau certification, Gurgaon to create better visualizations. However, many a times, there is a confusion between the two due to which analysts either use misuse it or totally avoid using it. Heat maps and tree maps are highly insightful visualizations. There are two very useful charts which help in analyzing data, heat maps and tree maps. Are you planning to pursue a Tableau training course in Delhi? Then you must be well aware of this common confusion about the difference between these two widely used maps.
