When working on a large dataset, scatterplots might become difficult to read, especially if you are looking for concentrations (densities) to judge the relationship and you have many observations that have the same or very similar values (overplotted points).

A standard plot, displays a marker for every data point. To produce a binned plot, imagine a grid be placed on the scatterplot; then count the number of data points in each grid cell and display a marker with a size (or a colour intensity) that reflects the number of points in each grid cell.

Select the data points, then double-click to get the Properties dialog, and tab to Binning [If the tab is not visible, you did not select a data point when double-clicking, but just the chart!]. You can also use or the tool.

You can either use marker size or color intensity to reflect the number of observations. Other options let you determine how the bins are constructed.

lets you remove binning if required.
