Visualisation of the measurement area in sample 9. A microscopy image of sample (a), showing the phloem fibres surrounded by other tissues. On right (b), the XRD image is constructed based on the intensity of the cellulose 200 reflection (i.e., the sum of the scattering intensities at q = 1.4–1.7 Å−1). The colour bar in image (b) represents the arbitrary intensity scale where the highest observed intensities are on white and the lowest on black. This same colour scale is used for all the XRD images representing the scattering intensities
