SymPlot (Symbol Plot)
Symplot allows 2D symbol/line plots in the rectangular/polar coordinates. One can type the x, y, dz data labels in the input boxes. But an easier way is to follow the step 1 to 8 (Only 3, 4, and 8 steps are required to plot though) as shown in the picture below. For multi-data sets, one can plot one set first, and then add more by selecting the plot panel from the 'Graph Panel' drop menu. Or check the 'From all the tables' to plot all the data sets at once from all the tables.
The picture below shows the configuration panel that enables the Graph modifications afterward. If you put $ something $ for any labels ($\lambda$ for example), it will accept LaTex commands for mathmatical fonts.
