• Add/remove labels.
• Plot data with various combinations of lines, markers, and error bars.
• Change the appearance/style of the of the plot, for example converting all text into Roman Font.
• Plot the data as a function of a different x variable.
• Change the number of panels in which the data is plotted.
• Define models and to calculate the 'best fit' parameter values.
