Labs(title='Demonstration of Raster Annotation') Geom_point(size=5,aes(shape=Feldspar,fill=Feldspar),color='black') + Theme_rgbw() + theme_nogrid() + theme_legend_position() +Īnnotation_raster_tern(FeldsparRaster,xmin=0,xmax=1,ymin=0,ymax=1) + Included in this ggtern 2.1.1 is raster-array data for Figure 6 from Elkins and Groves Feldspar, lets dive in and demonstrate how to overlay some fresh points over this existing figure, for the sake of convenience, lets use the data from the same paper for the points themselves.: Plagioclase feldspars are key components of terrestrial planets and deriving their phase diagram and activitycomposition relations has been the subject of. Several people have asked me how they can overlay their new data over the top of an existing ternary diagram, say from a publication and the like. This post will demonstrate the use of this requested feature. This includes a number of minor bug fixes, and an additional annotation, permitting the rendering of raster data, say for the inclusion of images. To display three variables in a ternary graph, their values must be normalized to a constant, usually either 1 or 100. Hi Folks, ggtern v2.1.1 has just been submitted to CRAN. A ternary or triangular diagram (chart/plot/graph) is a graphical way to display the relationship between three variables or components.
