Visualisation of phloem fibres by using (a) the cellulose 200 reflection intensity vs. (b) the mean microfibril angle values in sample 16. In (a), the XRD data given is constructed of the highest intensity around the cellulose 200 reflection (q = 1.4–1.7 Å−1). In (b), the visual presentation of the same sample area is constructed by using the microfibril angle value. The units of the MFA values are in degrees. The bright yellow colour (45 degrees) in (b) does not correspond to a real MFA value (i.e., it represents the background). The length scalebar is the same for both the pictures
