functions Array

An array of Javascript functions which should be evaluated to produce each column of the data set.

Once instantiated, the following methods of the JSPlot_FunctionEvaluator class can be used to generate JSPlot_DataSet instances:

Method Arguments Description
evaluate_linear_raster x_min – number
x_max – number
point_count – number
auto_update – boolean
Evaluate the functions at point_count linearly-spaced points between x_min and x_max.
evaluate_log_raster x_min – number
x_max – number
point_count – number
auto_update – boolean
Evaluate the functions at point_count log-spaced points between x_min and x_max.
evaluate_over_grid x_min – number
x_max – number
point_count_x – number
y_min – number
y_max – number
point_count_y – number
Evaluate the functions over a grid of linearly-spaced points along the x- and y-axes.
