Select at least one data column and one factor column to create main effects plot by factor(s).

Origin's Main Effects plot allows you selecting multiple response data as Input data and multiple categorical varaibles as Factors. Each input column will be plotted as a seperate Main Effects plot, and each factor will be plotted as a graph layer. In each layer, each value of the factor will be plotted as a data point with its mean response values. The mean of whole response data will be plotted as a dash reference line.
