Canoco 5 Gallery

Working with graphs

Canoco 5 not only offers all the graphing facilities enjoyed by the users of CanoDraw program in the Canoco for Windows 4.5 package, but extends them in many ways, some of them illustrated below.

The visual attributes of diagram contents can be preset using up to three different configurations (Colour, Black & white, and Custom) available across the projects and Canoco 5 sessions, but you can also adjust the properties of individual (selected) items within a particular graph using the Attribute Editor, as shown in the following snapshot. Note that it was substantially reworked, including a new preview of symbol look.

Created graphs can be exported from the analysis notebooks into separate files (with .c5g extension) that can be exchanged easily among Canoco 5 users or exported in one of the widely used graphic formats. Following snapshot illustrates the enhanced set of formats supported by the graph export, now including the JPG, TIFF, or PDF formats, many with user-selectable options.

Another useful extension is the possibility to make symbols / lines / fonts / areas partially transparent. This comes handy particularly when a scatter of symbols should represent more the density than the location of individual symbols, as illustrated in the following scatter diagram.

The enclosing polygons for symbols belonging to particular class can be newly filled and for this the partial transparency is also very useful.

Although the enclosing polygons remain the most precise presentation of the location of individual classes within the ordination space, Canoco 5 offers by popular demand the enclosing ellipses, as illustrated in the following snapshot. As shown below, the length of the major and minor axes of the fitted ellipses can be further adjusted.

Another useful visualization tool offered by Canoco 5 are the case-shift plots, visualizing the discrepancy between the case scores calculated from the response variable scores and those based on the explanatory variable values.

When the explanatory variable is a single factor, combining such case-shift scatter with the centroids of explanatory variables creates the star plot offered also (when appropriate) by the Graph Wizard and illustrated below.

Canoco 5 also offers the pie diagrams popular with CanoDraw users, but with an improved look.
