Cartesian charts represent data in a standard way. The data is expressed using a Cartesian system of coordinates (x, y). The x- and y-coordinates are plotted along the abscissa and ordinate scales, respectively. The scales are rectangular and are displayed orthogonally.

Polar charts represent data in a circular way. The data is expressed using a polar system of coordinates (θ, ρ). The abscissa values θ are plotted along a circular scale. The ordinate scale, along which the ρ-coordinates are plotted, is rectangular and is displayed radially.

Grids to help you locate the data points on a chart (see A Grid and a Legend in a Cartesian Chart)

Cursors that show the values of a given data point on the scales (see Cursors in a Cartesian Chart)
