The data and graph were contributed by Lu Tianrui in Hubei Engineering University.
This is a multiple-layer graph to shows XRD (X-ray diffraction) pattern. Peaks are compared with the standard substance plot (PDF card) and thus marked by different shapes of scatters representing different components.
To know how to plot this graph, please download the above project file (in the Zip file). There is a Note window to show the detail steps for plotting this graph.
