In Tableau, including a Pie Chart into a Scatter Plot is not an easy task to accomplish without some assistance. This blog has been written to walk you through a few visualization charts that can be used in Tableau to analyze data at a more in-depth level of understanding.
This article has been presented to guide you through a few visualization charts used in Tableau to analyse data at a greater level. The topics include how to create pie charts, scatter plot, Area Fill charts and Circular View in Tableau.
Compare the value of each kind of chart for displaying the information. All three charts are plotting the same data using Show Me to create the charts.

The line chart facilitates an accurate comparison of the relative sales by category. Since the area fill chart plots sales values as bands, it is easy to misinterpret the top band as being the largest value in the set. Area fill charts are best used for plotting a single dimension to avoid misunderstanding. Pie charts should be used for getting a general sense of magnitude and not for precise comparisons. A more effective use of a pie chart and area fill chart is provided in the below diagram.

Pie chart and area fill chart diagram:
By limiting the area fill chart to one dimension on each axis and using a pie chart with only three slices— the combination of chart types presents the information effectively. The pie chart acts as a filter for the area fill chart in the diagram. If you have limited space and are sure that your pie slices won’t be tiny, pie charts can be used effectively as filters.

Enabling analysis of granular data across multiple dimensions, scatter plots, circle views and side-by-side circles can be used to identify outliers.
Scatter plot, circle view, side-by-side circle view diagram:
All three charts in the above diagram are plotting over four thousand marks in a very small space. The scatter plot uses two axes for comparing profit and shipping cost. Color and shape provide insight into two dimensions. Size isn’t being used in the example but could be used for a third measure. The circle view uses one axis to plot a single measure. In both circle plots, size is used to denote the shipping cost amount. The side-by-side chart provides a more granular breakdown of the product categories.
