I have another data set on underground water mineral content measured along a river basin at three locations: Upper, Middle and Lower. The measured values are Hydrocarbonate, Chloride, Sulphate content and EC. I intended to upload the data but unfortunately, the Excel file formats are not accepted. I want to plot boxplots like the ones shown in the attached image in R using ggplot2. Would anyone help how I can do it? The measure variable should be o
face_wrap, I know it does however, all the 4 element, each should be on the x-axis with three boxplots for each location and for all the four measured variables should share a single y-axis as shown in the picture.
