2D Density Scatter Plot - Color Points by Kernel Density Estimate

Density Dots is a plot type introduced to create scatter plots to show data density.

The data is presented as a scatter plot where the points are color-mapped to the data density. The density is computed using Kernel Density Estimate

To calculate Kernel Density Estimate, OriginPro uses a fast algorithm that utilizes 2D binned approximation and 2D interpolation. It can create density dots plots from very large datasets on the order of millions of data points in seconds.

The algorithm has been validated by comparing Origin and R results from the same dataset.


From same dataset, OriginPro can generate similar plot to R. See details in Density Scatter Plot Validation page
