Select the ends for each columnΒΆ

A pollen diagram is defined through different columns, each column represents one taxa, species, PFT, etc.. To digitize the data, we have to know, where each column starts and ends exactly.

After having clicked the Column starts button, the software automatically estimates the starts of the columns and, based on that, the column ends as well. Clicking the ends button however lets you modify the automatically estimated column ends.

As for the column starts, there are two ways to modify the column ends:

  1. Hold the Shift button and left-click on the plot to create a new vertical mark.

    Then Left-click the mark and drag it to the start of one column.

  2. Delete a column start by right-clicking the mark.
