Both of these graphs depict the same information correctly. However, visually, the shape of the data is quite different. Curve manipulation is possible through the variability of the y-axis range. By changing the vertical axis field limits, the graph itself changes. In Version 1 of the data, the y-axis min/max scale has been calibrated to [40, 80]. The “slope” of the curve is steep, implying a drastic change. However, in Version 2 of the data set, the vertical axis limits have been set to [0, 100], which produces a flattened shape of the curve, which suggests a mellow increase. Here, two graphs depicting identical data sets can be represented in notably different ways, showing how the y-axis scale technique can be used to distort statistical details.
