EcoDATE Tutorial: Cone Production Data Case Study
This tutorial explains how to use the EcoDATE tool to explore the distribution patterns and temporal trends in a long-term ecological data set. The process can be broken up into three main steps: (1) import and configure data, (2) explore data with the multiple histograms views, and (3) explore data with the time-series line charts.
Figure 1: The EcoDATE interface for the cone production data set opened in a browser window. On the left is the multiple histograms view of a data subset. On the right is the time-series line chart showing the temporal trends of cone production among 14 individual trees.
