To investigate the crystal structure of a material sensitive to changes in environment, it is necessary to obtain diffraction data rapidly and accurately under a precisely controlled measurement environment. By combining a two-dimensional (2D) detector with attachments that precisely control ambient conditions such as temperature, humidity, and inert gas, even fast structural changes are revealed in the 2D diffraction patterns. Massive 2D data obtained during the in-situ measurement can easily be converted to 2θ-intensity (I) data by the Data Visualization (DV) plugin of SmartLab Studio II. In addition, the DV plugin includes useful functions that batch-process all structural parameters, such as peak position, d-value, crystallite size, etc., and plot all of them on one graph. Here, this outstanding feature of the DV plugin is demonstrated through the data pro- cessing of a large number of 2D images of vegetable based cream (VBC) obtained by DSC and HyPix-3000.
