Notes:
The graphical representation of results is usually accomplished today on a computer using a program such as Microsoft’s Excel. There are many ways of visualizing data such as a bar graph, a line graph, or a scatter plot, but in most cases the numerical resulting from the changing of some parameter is recorded.
Line and scatter plots will be discussed here. If the parameter is being change at a constant rate, then only the response is necessary because value of the parameter being varied can be calculate. This is called a line plot.
If the parameter is being changed in a non linear fashion, the both the value of the parameter and the value of the results must be recorded and a scatter plot results.
In either case, a explanatory variable is varied and placed on the x-axis, and the results or response variable is recorded and placed on the y-axis. Several Y axis are available but only one X axis.
