Different plotting styles can be selected in the operation window of MIRA. We clicked the "subsets" in the "data" to adjust the color code of the graph, and then clicked "XLoadct" in the "tools" to select the color of the chart; we could also select "Modify" to remove the extreme value or background interference of the SECM image, and finally, in the "IDL image window," the two-dimensional and three-dimensional images could be plotted at the same time, showing the current values of the x, y, and z-axis.
