TECHNIQUES FOR AUTOMATIC AND DYNAMIC OPACITY SETTINGS FOR SCATTERPLOTS

摘要

An opacity engine for automatically and dynamically setting an opacity level for a scatterplot based on a predetermined value for a mean opacity level of utilized pixels (MOUP) in the scatterplot. The opacity engine may automatically set the opacity level for the scatterplot to produce the predetermined MOUP value in the scatterplot. A utilized pixel in the scatterplot comprises a pixel displaying at least one data point representing data. The MOUP value in the scatterplot may be equal to the sum of the final opacity levels of all utilized pixels in the chart, divided by the number of utilized pixels in the chart. The predetermined MOUP value may be between 35%-45%, such as 40%. The opacity engine may adjust the determined opacity level for charts having relatively low over-plotting factors.

1. A computer-implemented method for setting opacity levels for scatterplot charts, the method comprising:
displaying a plurality of data points on a scatterplot chart, the data points being derived from a dataset; and determining an opacity level setting for the plurality of data points based at least in part on a predetermined value for a mean opacity level of utilized pixels (MOUP) in the scatterplot chart, wherein each utilized pixel in the scatterplot chart comprises a pixel that represents at least one data point in the plurality of data points.
