The Epi Curve diagram can be created from the Comparison Table. It shows the distribution of Samples (y axis) during a time period (x axis). Sample groups are indicated by colors.

The Time Scale can be changed to year, quarter, month, week or day. Sample with an inaccurate date according to the selected scale (e.g., scale is day, but Sample has only the year as collection date) are drawn with a white inner border.

The Cell Height can be controlled with the slider. Note that no boxes are painted around the Samples if the cell height is very low.
