As a rule, each individual point in a scatter chart is based on a single unit. As such, these charts cannot be published unless the data has been grouped so that each point represents multiple observations.
Scatter charts may only be published if the underlying data would meet anonymisation requirements in tabular form. The assessment must also consider whether the combination of variables used could enable individual identification.
You can improve the anonymity of scatter charts by replacing them with a graph depicting the frequency of observations in grid cells or by adding randomness to your points.
