plotframe - plot a frame with scaling and grids
Calling Sequence
- plotframe(rect,tics,[arg_opt1,arg_opt2,arg_opt3])
Parameters
- rect
: vector [xmin,ymin,xmax,ymax].
- tics
: vector [nx,mx,ny,my] where mx, nx (resp. my, ny) are the number of x-axis (resp. y-axis) intervals and subintervals.
- arg_optX
: optional arguments up to three and choosen among.
- flags
: vector [wantgrids,findbounds] where wantgrids is a boolean variable (%t or %f) which indicates gridding. findbounds is a boolean variable. If findbounds is %t, the bounds given in rect are allowed to be slightly modified (in fact always increased) in order to have simpler graduations: then tics(2) and tics(4) are ignored.
- captions
: vector of 3 strings [title,x-leg,y-leg] corresponding respectively to the title of the plot and the captions on the x-axis and the y-axis.
- subwin
: a vector of size 4 defining the sub window. The sub window is specified with the parameter subwin=[x,y,w,h] (upper-left, width, height). The values in subwin are specified using proportion of the width or height of the current graphics window (see xsetech).
Description
plotframe is used with 2D plotting functions plot2d,
plot2d1,... to set a graphics frame. It must be
used before plot2d which should be invoked with
the "000" superposition mode.
Examples
x=[-0.3:0.8:27.3]';
y=rand(x);
rect=[min(x),min(y),max(x),max(y)];
tics=[4,10,2,5]; //4 x-intervals and 2 y-intervals
plotframe(rect,tics,[%f,%f],["My plot","x","y"],[0,0,0.5,0.5])
plot2d(x,y,2,"000")
plotframe(rect,tics,[%t,%f],["My plot with grids","x","y"],[0.5,0,0.5,0.5])
plot2d(x,y,3,"000")
plotframe(rect,tics,[%t,%t],..
["My plot with grids and automatic bounds","x","y"],[0,0.5,0.5,0.5])
plot2d(x,y,4,"000")
plotframe(rect,tics,[%f,%t],..
["My plot without grids but with automatic bounds","x","y"],..
[0.5,0.5,0.5,0.5])
plot2d(x,y,5,"000")
xset("default")
