a Gradients of each elements with violin plots showing the distribution of values over all samples and bar plot showing the average value of each of these distributions. b Averaged Raman signal colored by the sample-averaged gradients (top panel), and the sample-averaged gradients are also plotted in the bottom panel (black line) with the respective ±1 standard deviation (green area) representing variation over the sampled parameter space. c, d The relationship between P and each composition (c) and spectrum (d) dimension of the source data, as quantified by Random Forest feature importance (Rand.For. FI), Maximal information coefficient (MIC), and Pearson correlation coefficient (Pearson)
