What variables are plotted on a graph?
A graph is made to better interprete the data. Typically, the x-axis is used to plot the independent variable. If you are plotting a time series, then the time variable (hours, days, years) is shown on the x-axis. Chosing which variables to plot can be difficult. Let's say I want to study employees salary. I would by convention plot on the X-axis, a factor which I think effects salary, say years of employment or education level. What variables should not be plotted? If my data set is very small, or not reliable, then the graph will add little value.
