dashurve
Dashurve is a term used in data visualization and time-series analysis to describe a stylized pattern in which short, transient events (dashes) punctuate a longer, smooth curve (urve). The concept is used informally to discuss how data can simultaneously exhibit both abrupt changes and gradual trends within the same series. The term combines dash and curve, and first appeared in visualization discussions in the mid-2010s. It has no formal mathematical definition in standard statistics; rather, it serves as a heuristic to describe data behavior.
Typically, a dashurve pattern features a high-frequency component of rapid spikes or dashed events overlaid on
In practice, analysts invoke the dashurve concept to discuss multimodal or bursty behavior and to motivate
