Plotting functions


Graph

Plots one or more columns as separate graphs. The x coordinates are set automatically to 1,2,3,...
There are three plot styles available: Graph (lines), bars and points. The 'X labels' options sets the x axis labels to the appropriate row names.

XY graph

Plots two columns containing x/y coordinate pairs. The 'log Y' option log-transforms your Y values (if necessary, a constant is added to make the minimum log value equal to 0). The curve can also be smoothed using 3-point moving average.

Histogram

Plots histograms (frequency distributions) for one or more columns. The number of bins is 10 by default, but can be changed by the user.

Ternary

Ternary plot for three columns of data, normally containing proportions of compositions.

Survivorship

Survivorship curves for one or more columns of data. The data will normally consist of age or size values. A survivorship plot shows the number of individuals which survived to different ages. Assuming exponential growth (highly questionable!), size should be log-transformed to age. This can be done either in the Massage menu, or directly in the Survivorship dialogue.
