The August 2023 update for Power BI introduced new options for bubble chart sizes. New features enable users to define their own bubble size in relation to data range and magnitude.
In addition to scatter and bubble charts, Power BI now also supports dot plot charts, offering a swath of possibilities from comparing large quantities of data without a predefined time series to illustrating relationships between values.
Scatter charts plot two groups of numbers as one series of x and y coordinates, revealing relationships between these two numerical values and highlighting patterns in large data sets.
Bubble charts build upon scatter charts by adding a third data series, represented as bubbles of varying sizes.
Dot plot charts build upon scatter charts capabilities with added category information on the x axis.
Scatter, bubble, and dot plot charts play significant roles in advanced data visualization. These charts let us process and exploit raw data far beyond what numeric values alone can convey. By enabling trends, relationships, and patterns to be visually discernible, they help optimise data that otherwise may be inscrutable. Hence, Power BI's integration of these charts empowers organizations to make better, more informed decisions derived from their data.
Power BI provides three chart visualizations that can help to reveal relationships and patterns in data: scatter charts, bubble charts, and dot plot charts. Scatter charts display data along a horizontal (x) and vertical (y) axis, with data points representing the intersection of the two axes. Bubble charts expand on the concept of data points by representing two intersected values with a bubble, with the bubble size representing a third data dimension. Dot plot charts further expand on the capabilities of the scatter chart by allowing you to add categorical data on the horizontal axis. Tooltips are available for all data points in scatter, bubble, and dot plot charts, providing additional details for the data. Additionally, you can adjust the independent scales of the axes to reveal more information about the grouped values. Maximum data points of 10,000 can be set, and the chart visualizations can identify interesting information about your data that might not be readily apparent by just looking at the numerical values. This month, the Power BI team released two new options for representing bubble size in Power BI charts: Data range and magnitude. With these options, users can better analyze large sets of data and quickly identify trends, clusters, and outliers.
