Algorithm (Workflow)
This function, CPLplothatched, is designed to plot a Contour Path Line (CPL) with a hatched pattern. It is part of the SolidGeometry library and was introduced in version 5.2. The function takes in a CPL and optional parameters for color and hatch pattern, and returns a handle to the plot.
Input Parameters
- CPL: The main input, representing the Contour Path Line to be plotted.
- c: An optional parameter for color. If not provided, it defaults to 'r' (red).
- al: An optional parameter that defines the hatch pattern. It is an array with three elements: [alpha, width, distance]. If not provided, it defaults to [60, 0, 4].
Output
- h: A handle to the plot, which can be used for further manipulation or querying of the plot.
Algorithm Steps
- The function starts by retrieving the color parameter
c using getfuncparams. If not specified, it defaults to 'r'.
- It then retrieves the hatch pattern parameters
al using getfuncparams. If not specified, it defaults to [60, 0, 4].
- The function calls
CPLhatch with the CPL and the hatch pattern parameters al(2:3) and al(1) to generate the hatched pattern.
- Finally, it plots the CPL using
CPLplot and the hatched pattern using CPSplot, both with the specified color c. The handles to these plots are combined and returned as h.
