Dear Jacob, Do you want something like this? Using dummy data instead of yours. Copy-paste the output of dput() if you want to pass your data in a format that is easy to use.
library(ggplot2) dataset <- expand.grid(X = -3:3, Depth = seq(0, -1, by = -0.25)) dataset$Resistivity <- rnorm(nrow(dataset), mean = 1) ggplot(dataset, aes(x = X, y = Depth, fill = Resistivity)) + geom_tile() HTH, Thierry ------------------------------------------------------------------------ ---- ir.
