Setting the ordinate of the y-axis at 0 ensures that the changes in the variable are accurately represented and avoids exaggerating the differences between values. This is particularly important with ratio data, which has a meaningful zero point and can have very large or very small values. Setting the y-axis at a value other than zero can distort the visual representation of the data and potentially lead to misinterpretation. Setting the axis at zero ensures that the graph accurately reflects the values of the data and helps to avoid misleading conclusions.
