Data Features
The data to be represented in a chart can have different forms:
*Sets of data points with two coordinates
*Sets of data values
*Functions of the type y = f(x) that can be described by a script or a C++ callback
The data can be expressed in:
*A Cartesian system of coordinates (x, y)
*A polar system of coordinates (θ, ρ)
The abscissa values (x or θ) are plotted along the abscissa scale and the ordinate values (y or ρ) are plotted along the ordinate scale(s).
Graphical Representations of Data
The following predefined graphical representations of data are available:
*Scatter (data displayed with markers)
*Polyline, polygon, and marked polyline (polyline with markers)
*Bar and 3D bar
*Step (data displayed with only the steps of the stairs) and stair (data displayed with the entire stairs)
*Fixed step (data displayed with fixed steps centered on the data)
*Stock representations including high-low representation made of lines, high-low representations made of bars, high-low open-close representations
*Bubble (data displayed with bubbles)
*Pie charts
*Side-by-side bars
*Stacked representations (100% stacked or not) including stacked bars, stacked 3D bars, stacked polygons
