Syntax
[C/C++:]
void ggPlotGraph(int npts, GPOINT *points, int scx, int scy, int style, int axis);
[F90:]
subroutine ggPlotGraph(npts, points, scx, scy, style, axis)
integer, intent(in) :: npts, scx, scy, style, axis
type(GPOINT), intent(in) :: points(*)
Arguments
npts
The number of points to be plotted
points
Array of dimension
npts, giving the X and axis values of the points to be defined on the graph
scx
The type of scaling used on the X axis
|
= GLINEAR |
Linear scale on X axis |
|
= GLOG10 |
Log10 scale on X axis |
scy
The type of scaling used on the Y axis
|
= GLINEAR |
Linear scales on Y axis |
|
= GLOG10 |
Log10 scale on Y axis |
style
Type of graph
|
= GSYMBOLS |
Symbol drawn at each data point |
|
= GSTRAIGHT |
Points drawn with straight lines |
|
= GCUBIC |
Points joined with piecewise smooth parametric cubic curve |
|
= GAKIMA |
Point joined with smooth Akima curve |
|
= GSPLINE |
Points joined with parametric cubic spline |
Negative values of the above will add a symbol at each point.
axis
Type of axes
|
= GFRAME |
A frame is drawn |
|
= GAXES |
Axes are drawn through origin of data (if present) or at the bottom left corner of drawing area
|
Description
The routine ggPlotGraph() is a general purpose graph drawing routine that plots the data supplied in the components
points.x and
points.y according to the above arguments. The graph is drawn to fit the available drawing area or current window. Scaling and annotation are performed automatically.
The resultant curve drawn with
style=GCUBIC or GSPLINE can extend outside the graph frame or drawing area. The curve end conditions may be set by using the routines ggSetCurveStartConds() and/or ggSetCurveEndConds().
Graphs with
style= GSYMBOLS or GSTRAIGHT, can be affected by the current missing value mode as set by the routine ggDefineMissingValues().
The default axes annotation may be changed using the routines ggSetAxesAnnotation() and/or ggSetAxesAttribs().The default data ranges and axes intervals can be changed using the routine ggSetGraphScaling().
