1. A method performed at a computer system comprising one or more processors, for displaying one or more dimensionally transformed datasets, the method comprising: generating, at the computer system, a dimensionality reduction transformation function representing a first time series, including at least: receiving, at the computer system, the first time series collected from tracing a computer application at a first time, the first time series comprising performance data for a plurality of functions of the computer application observed while tracing the computer application at the first time; processing, at the computer system, the first time series data into one or more time series vectors; and creating, at the computer system, a dimensionality reduction transformation function by identifying one or more principal components within the one or more time series vectors; receiving, at the computer system, a second time series collected from tracing the computer application at a second time; applying, at the computer system, the dimensionality reduction transformation function to the first time series and the second time series to generate a transformed dataset comprising at least the identified principal components of the first time series and the second time series; and causing the transformed dataset to be displayed at a display of the computer system.
