In this experiment, the gain in mass should be plotted along the Y axis while the time (in weeks) should be plotted along the X axis of the graph.

The easiest pattern of reporting experimental results in science is by the use of a graph. A graph is a diagrammatic representation of the relationship between two variables along the X-Y Cartesian axes.

In this experiment, we are trying to represent the relationship between the gain in mass and time taken. The experiment is scheduled to run over a course of ten weeks.

The X axis ought to represent the time in weeks while the Y axis ought to represent the gain in mass.

This derives from the fact that it is conventional for the dependent variable (in this case gain in mass) to be plotted along the Y axis while the independent variable (time) to be plotted along the X axis.
