B.17.2 Examples

Here are some examples of using plot2corner:

stilts plot2corner in=:attractor:100000,rampe
                   nvar=3 x1=x x2=y x3=z
                   layer_m=mark

Plots a grid of scatter plots for a 3-d dataset. This presents three plots: X vs. Y, X vs. Z, and Y vs. Z in the lower triangle of the grid.

stilts plot2corner in=:attractor:100000,rampe
                   nvar=3 x1=x x2=y x3=z
                   matrixformat=full
                   layer_m=mark layer_h=histogram

Same as the previous example, but also presents histograms (one each for X, Y and Z) along the diagonal. Additionally, the matrixformat=full parameter means that the full grid (with redundant plots also for Y vs. X, Z vs. X, and Z vs. Y) are plotted above the diagonal.

stilts plot2corner in=rrlyrae.fits
                   icmd_A='select best_classification==\"RRAB\"'
                   icmd_C='select best_classification==\"RRC\"'
                   color_A=red color_C=cyan
                   nvar=4 x1=peak_to_peak_g x2=p1 x3=r21_g x4=phi21_g x4min=3
                   layer_A_m=mark layer_C_m=mark
                   layer_A_k=kde layer_C_k=kde smooth_A_k=-50 smooth_C_k=-50
                   layer_f=contour color_f=light_grey smooth_f=10 nlevel_f=6
                   leglabel_A=RRAB leglabel_C=RRC legseq=_A_m,_C_m legpos=1,1

In this example there are two separate input datasets (different selections from the same input table) and four quantities to plot. One of the coordinates is restricted in range using the x4min parameter. As well as the mark and kde layers, an additional contour layer (of the whole input table) is overplotted on the scatter plot grid elements.
