Prism also now has semi-transparent color schemes built in so that overlapping symbols can be more clearly seen. However, now the color of the symbol represents that country's birth rate per 1000 individuals on a continuous scale.

In this graph, the X-coordinate, Y-coordinate, and size of the symbols is the same as before. This final variable (color) in this case is a categorical variable, but color in Bubble Plots can also be defined by continuous variables: Finally, the color of each symbol represents the continent in which the country is located. The size of each symbol is proportionate to the population of the country it represents (with the two largest symbols representing China and India, respectively). The X-coordinate of each circle represents that country's GDP (PPP), while the Y-coordinate represents the average life expectancy at birth. On this graph, over 100 countries are shown as individual circles. Prism provides an extensive library of analyses from common to highly specific t tests, one-, two- and three-way ANOVA, linear and nonlinear regression, dose-response curves, binary logistic regression, survival analysis, principal component analysis, etc. Note that both symbol color and symbol size can be defined using a categorical (grouping) OR a continuous variable. GraphPad Prism can help you perform detailed analysis and graphing of your data. Create Bubble Plots directly from raw data, encoding variables for symbol position (X- and Y-coordinates), size, and fill color.
