6 PDL::Graphics::PLplot - Object-oriented interface from perl/PDL to the
7 PLPLOT plotting library
8
10 use PDL;
11 use PDL::Graphics::PLplot;
12 my $pl = PDL::Graphics::PLplot->new (DEV => "png", FILE => "test.png");
14 my $x = sequence(10);
15 my $y = $x**2;
16 $pl->xyplot($x, $y);
17 $pl->close;
18 For more information on PLplot, see
20 http://www.plplot.org/
22 Also see the test file, t/plplot.pl in this distribution for some
24 working examples.
25
27 This is the PDL interface to the PLplot graphics library. It is
28 designed to be simple and light weight with a familiar 'perlish' Object
29 Oriented interface.
30
32 The following options are supported. Most options can be used with any
33 function. A few are only supported on the call to 'new'.
34 Options used upon creation of a PLplot object (with 'new'):
36 BACKGROUND
37 Set the color for index 0, the plot background
39 DEV
41 Set the output device type. To see a list of allowed types, try:
43 PDL::Graphics::PLplot->new();
45 PDL::Graphics::PLplot->new(DEV => 'png', FILE => 'test.png');
47 FILE
49 Set the output file or display. For file output devices, sets the
51 output file name. For graphical displays (like 'xwin') sets the name
52 of the display, eg ('hostname.foobar.com:0')
53 PDL::Graphics::PLplot->new(DEV => 'png', FILE => 'test.png');
55 PDL::Graphics::PLplot->new(DEV => 'xwin', FILE => ':0');
56 OPTS
58 Set plotting options. See the PLplot documentation for the complete
60 listing of available options. The value of 'OPTS' must be a hash
61 reference, whose keys are the names of the options. For instance, to
62 obtain PostScript fonts with the ps output device, use:
63 PDL::Graphics::PLplot->new(DEV => 'ps', OPTS => {drvopt => 'text=1'});
65 MEM
67 This option is used in conjunction with "DEV => 'mem'". This option
69 takes as input a PDL image and allows one to 'decorate' it using
70 PLplot. The 'decorated' PDL image can then be written to an image file
71 using, for example, PDL::IO::Pic. This option may not be available if
72 plplot does not include the 'mem' driver.
73 # read in Earth image and draw an equator.
75 my $pl = PDL::Graphics::PLplot->new (MEM => $earth, DEV => 'mem');
76 my $x = pdl(-180, 180);
77 my $y = zeroes(2);
78 $pl->xyplot($x, $y,
79 BOX => [-180,180,-90,90],
80 VIEWPORT => [0.0, 1.0, 0.0, 1.0],
81 XBOX => '', YBOX => '',
82 PLOTTYPE => 'LINE');
83 $pl->close;
84 FRAMECOLOR
86 Set color index 1, the frame color
88 JUST
90 A flag used to specify equal scale on the axes. If this is not
92 specified, the default is to scale the axes to fit best on the page.
93 PDL::Graphics::PLplot->new(DEV => 'png', FILE => 'test.png', JUST => 1);
95 ORIENTATION
97 The orientation of the plot:
99 0 -- 0 degrees (landscape mode)
101 1 -- 90 degrees (portrait mode)
102 2 -- 180 degrees (seascape mode)
103 3 -- 270 degrees (upside-down mode)
104 Intermediate values (0.2) are acceptable if you are feeling daring.
106 # portrait orientation
108 PDL::Graphics::PLplot->new(DEV => 'png', FILE => 'test.png', ORIENTATION => 1);
109 PAGESIZE
111 Set the size in pixels of the output page.
113 # PNG 500 by 600 pixels
115 PDL::Graphics::PLplot->new(DEV => 'png', FILE => 'test.png', PAGESIZE => [500,600]);
116 SUBPAGES
118 Set the number of sub pages in the plot, [$nx, $ny]
120 # PNG 300 by 600 pixels
122 # Two subpages stacked on top of one another.
123 PDL::Graphics::PLplot->new(DEV => 'png', FILE => 'test.png', PAGESIZE => [300,600],
124 SUBPAGES => [1,2]);
125 Options used after initialization (after 'new')
127 BOX
128 Set the plotting box in world coordinates. Used to explicitly set the
130 size of the plotting area.
131 my $pl = PDL::Graphics::PLplot->new(DEV => 'png', FILE => 'test.png');
133 $pl->xyplot ($x, $y, BOX => [0,100,0,200]);
134 CHARSIZE
136 Set the size of text in multiples of the default size. "CHARSIZE =>
138 1.5" gives characters 1.5 times the normal size.
139 COLOR
141 Set the current color for plotting and character drawing. Colors are
143 specified not as color indices but as RGB triples. Some pre-defined
144 triples are included:
145 BLACK GREEN WHEAT BLUE
147 RED AQUAMARINE GREY BLUEVIOLET
148 YELLOW PINK BROWN CYAN
149 TURQUOISE MAGENTA SALMON WHITE
150 ROYALBLUE DEEPSKYBLUE VIOLET STEELBLUE1
151 DEEPPINK MAGENTA DARKORCHID1 PALEVIOLETRED2
152 TURQUOISE1 LIGHTSEAGREEN SKYBLUE FORESTGREEN
153 CHARTREUSE3 GOLD2 SIENNA1 CORAL
154 HOTPINK LIGHTCORAL LIGHTPINK1 LIGHTGOLDENROD
155 # These two are equivalent:
157 $pl->xyplot ($x, $y, COLOR => 'YELLOW');
158 $pl->xyplot ($x, $y, COLOR => [0,255,0]);
159 LINEWIDTH
161 Set the line width for plotting. Values range from 1 to a device
163 dependent maximum.
164 LINESTYLE
166 Set the line style for plotting. Pre-defined line styles use values 1
168 to 8, one being a solid line, 2-8 being various dashed patterns.
169 MAJTICKSIZE
171 Set the length of major ticks as a fraction of the default setting.
173 One (default) means leave these ticks the normal size.
174 MINTICKSIZE
176 Set the length of minor ticks (and error bar terminals) as a fraction
178 of the default setting. One (default) means leave these ticks the
179 normal size.
180 NXSUB
182 The number of minor tick marks between each major tick mark on the X
184 axis. Specify zero (default) to let PLplot compute this automatically.
185 NYSUB
187 The number of minor tick marks between each major tick mark on the Y
189 axis. Specify zero (default) to let PLplot compute this automatically.
190 PALETTE
192 Load pre-defined color map 1 color ranges. Currently, values include:
194 RAINBOW -- from Red to Violet through the spectrum
196 REVERSERAINBOW -- Violet through Red
197 GREYSCALE -- from black to white via grey.
198 REVERSEGREYSCALE -- from white to black via grey.
199 GREENRED -- from green to red
200 REDGREEN -- from red to green
201 # Plot x/y points with the z axis in color
203 $pl->xyplot ($x, $y, PALETTE => 'RAINBOW', PLOTTYPE => 'POINTS', COLORMAP => $z);
204 PLOTTYPE
206 Specify which type of XY plot is desired:
208 LINE -- A line
210 POINTS -- A bunch of symbols
211 LINEPOINTS -- both
212 SUBPAGE
214 Set which subpage to plot on. Subpages are numbered 1 to N. A zero
216 can be specified meaning 'advance to the next subpage' (just a call to
217 pladv()).
218 my $pl = PDL::Graphics::PLplot->new(DEV => 'png',
220 FILE => 'test.png',
221 SUBPAGES => [1,2]);
222 $pl->xyplot ($x, $y, SUBPAGE => 1);
223 $pl->xyplot ($a, $b, SUBPAGE => 2);
224 SYMBOL
226 Specify which symbol to use when plotting "PLOTTYPE => 'POINTS'". A
228 large variety of symbols are available, see:
229 http://plplot.sourceforge.net/examples-data/demo07/x07.*.png, where *
230 is 01 - 17.
231 SYMBOLSIZE
233 Specify the size of symbols plotted in multiples of the default size
235 (1). Value are real numbers from 0 to large.
236 TEXTPOSITION
238 Specify the placement of text. Either relative to border, specified
240 as:
241 [$side, $disp, $pos, $just]
243 Where
245 side = 't', 'b', 'l', or 'r' for top, bottom, left and right
247 disp is the number of character heights out from the edge
248 pos is the position along the edge of the viewport, from 0 to 1.
249 just tells where the reference point of the string is: 0 = left, 1 = right, 0.5 = center.
250 or inside the plot window, specified as:
252 [$x, $y, $dx, $dy, $just]
254 Where
256 x = x coordinate of reference point of string.
258 y = y coordinate of reference point of string.
259 dx Together with dy, this specifies the inclination of the string.
260 The baseline of the string is parallel to a line joining (x, y) to (x+dx, y+dy).
261 dy Together with dx, this specifies the inclination of the string.
262 just Specifies the position of the string relative to its reference point.
263 If just=0, the reference point is at the left and if just=1,
264 it is at the right of the string. Other values of just give
265 intermediate justifications.
266 # Plot text on top of plot
268 $pl->text ("Top label", TEXTPOSITION => ['t', 4.0, 0.5, 0.5]);
269 # Plot text in plotting area
271 $pl->text ("Line label", TEXTPOSITION => [50, 60, 5, 5, 0.5]);
272 TITLE
274 Add a title on top of a plot.
276 # Plot text on top of plot
278 $pl->xyplot ($x, $y, TITLE => 'X vs. Y');
279 VIEWPORT
281 Set the location of the plotting window on the page. Takes a four
283 element array ref specifying:
284 xmin -- The coordinate of the left-hand edge of the viewport. (0 to 1)
286 xmax -- The coordinate of the right-hand edge of the viewport. (0 to 1)
287 ymin -- The coordinate of the bottom edge of the viewport. (0 to 1)
288 ymax -- The coordinate of the top edge of the viewport. (0 to 1)
289 # Make a small plotting window in the lower left of the page
291 $pl->xyplot ($x, $y, VIEWPORT => [0.1, 0.5, 0.1, 0.5]);
292 # Also useful in creating color keys:
294 $pl->xyplot ($x, $y, PALETTE => 'RAINBOW', PLOTTYPE => 'POINTS', COLORMAP => $z);
295 $pl->colorkey ($z, 'v', VIEWPORT => [0.93, 0.96, 0.15, 0.85]);
296 XBOX
298 Specify how to label the X axis of the plot as a string of option
300 letters:
301 a: Draws axis, X-axis is horizontal line (y=0), and Y-axis is vertical line (x=0).
303 b: Draws bottom (X) or left (Y) edge of frame.
304 c: Draws top (X) or right (Y) edge of frame.
305 f: Always use fixed point numeric labels.
306 g: Draws a grid at the major tick interval.
307 h: Draws a grid at the minor tick interval.
308 i: Inverts tick marks, so they are drawn outwards, rather than inwards.
309 l: Labels axis logarithmically. This only affects the labels, not the data,
310 and so it is necessary to compute the logarithms of data points before
311 passing them to any of the drawing routines.
312 m: Writes numeric labels at major tick intervals in the
313 unconventional location (above box for X, right of box for Y).
314 n: Writes numeric labels at major tick intervals in the conventional location
315 (below box for X, left of box for Y).
316 s: Enables subticks between major ticks, only valid if t is also specified.
317 t: Draws major ticks.
318 The default is 'BCNST' which draws lines around the plot, draws major
320 and minor ticks and labels major ticks.
321 # plot two lines in a box with independent X axes labeled
323 # differently on top and bottom
324 $pl->xyplot($x1, $y, XBOX => 'bnst', # bottom line, bottom numbers, ticks, subticks
325 YBOX => 'bnst'); # left line, left numbers, ticks, subticks
326 $pl->xyplot($x2, $y, XBOX => 'cmst', # top line, top numbers, ticks, subticks
327 YBOX => 'cst', # right line, ticks, subticks
328 BOX => [$x2->minmax, $y->minmax]);
329 XERRORBAR
331 Used only with "xyplot". Draws horizontal error bars at all points
333 ($x, $y) in the plot. Specify a PDL containing the same number of
334 points as $x and $y which specifies the width of the error bar, which
335 will be centered at ($x, $y).
336 XLAB
338 Specify a label for the X axis.
340 XTICK
342 Interval (in graph units/world coordinates) between major x axis tick
344 marks. Specify zero (default) to allow PLplot to compute this
345 automatically.
346 YBOX
348 Specify how to label the Y axis of the plot as a string of option
350 letters. See "XBOX".
351 YERRORBAR
353 Used only for xyplot. Draws vertical error bars at all points ($x, $y)
355 in the plot. Specify a PDL containing the same number of points as $x
356 and $y which specifies the width of the error bar, which will be
357 centered at ($x, $y).
358 YLAB
360 Specify a label for the Y axis.
362 YTICK
364 Interval (in graph units/world coordinates) between major y axis tick
366 marks. Specify zero (default) to allow PLplot to compute this
367 automatically.
368 ZRANGE
370 For "xyplot" (when "COLORMAP" is specified), for "shadeplot" and for
372 "colorkey". Normally, the range of the Z variable (color) is taken as
373 "$z->minmax". If a different range is desired, specify it in "ZRANGE",
374 like so:
375 $pl->shadeplot ($z, $nlevels, PALETTE => 'GREENRED', ZRANGE => [0,100]);
377 or
379 $pl->xyplot ($x, $y, PALETTE => 'RAINBOW', PLOTTYPE => 'POINTS',
381 COLORMAP => $z, ZRANGE => [-90,-20]);
382 $pl->colorkey ($z, 'v', VIEWPORT => [0.93, 0.96, 0.13, 0.85],
383 ZRANGE => [-90,-20]);

421 $pl->setparm (TEXTSIZE => 2);
423 xyplot
425 Plot XY lines and/or points. Also supports color scales for points.
426 This function works with bad values. If a bad value is specified for a
427 points plot, it is omitted. If a bad value is specified for a line
428 plot, the bad value makes a gap in the line. This is useful for
429 drawing maps; for example $x and $y can be the continent boundary
430 latitude and longitude.

450 $pl->xyplot($x, $y, PALETTE => 'RAINBOW', PLOTTYPE => 'POINTS', COLORMAP => $z);
451 stripplots
453 Plot a set of strip plots with a common X axis, but with different Y
454 axes. Looks like a stack of long, thin XY plots, all line up on the
455 same X axis.
456 Arguments:
458 $x -- 1D PDL with common X axis values, length = N
459 $ys -- 2D PDL with M Y-axis values: N x M

483 COLOR => ['GREEN', 'DEEPSKYBLUE', 'DARKORCHID1', 'DEEPPINK'], XLAB => 'X label');
484 In addition, COLOR may be specified as a reference to a list of colors. If
486 this is done, the colors are applied separately to each plot.
487 Also, the options Y_BASE and Y_GUTTER can be specified. Y_BASE gives the Y offset
489 of the bottom of the lowest plot (0-1, specified like a VIEWPORT, defaults to 0.1) and Y_GUTTER
490 gives the gap between the graphs (0-1, default = 0.02).
491 colorkey
493 Plot a color key showing which color represents which value
494 Arguments:
496 $range : A PDL which tells the range of the color values

515 $pl->colorkey ($z, 'v', VIEWPORT => [0.93, 0.96, 0.15, 0.85]);
516 shadeplot
518 Create a shaded contour plot of 2D PDL 'z' with 'nsteps' contour
519 levels. Linear scaling is used to map the coordinates of Z(X, Y) to
520 world coordinates via the "BOX" option.

565 bargraph
567 Simple utility to plot a bar chart with labels on the X axis. The
568 usual options can be specified, plus one other: MAXBARLABELS specifies
569 the maximum number of labels to allow on the X axis. The default is
570 20. If this value is exceeded, then every other label is plotted. If
571 twice MAXBARLABELS is exceeded, then only every third label is printed,
572 and so on.

631 close
633 Close a PLplot object, writing out the file and cleaning up.
634 Arguments: None
636 Returns: Nothing
638 This closing of the PLplot object can be done explicitly though the
640 'close' method. Alternatively, a DESTROY block does an automatic close
641 whenever the PLplot object passes out of scope.
642 $pl->close;
644
646 The PDL low-level interface to the PLplot library closely mimics the C
647 API. Users are referred to the PLplot User's Manual, distributed with
648 the source PLplot tarball. This manual is also available on-line at
649 the PLplot web site (<http://www.plplot.org/>).
650 There are though two differences in way the functions are called. The
652 first one is due to a limitation in the pp_def wrapper of PDL, which
653 forces all the non-piddle arguments to be at the end of the arguments
654 list. It is the case of strings ("char *") arguments in the C API.
655 This affects the following functions [shown below with their prototypes
656 in PDL, with arguments preceded by "(pdl)" are piddle-convertible; see
657 the PLplot manual for the meaning of the arguments]:
658 plaxes ((pdl) x0, (pdl) y0, (pdl) xtick, (pdl) nxsub, (pdl) ytick,
660 (pdl) nysub, (string) xopt, (string (yopt))
661 plbox ((pdl) xtick, (pdl) nxsub, (pdl) ytick, (pdl) nysub,

663 plbox3 ((pdl) xtick, (pdl) nsubx, (pdl) ytick, (pdl) nsuby,
664 (pdl) ztick, (pdl) nsubz, (string) xopt, (string) xlabel,
665 (string) yopt, (string) ylabel, (string) zopt,

670 The second notable different between the C and the PDL APIs is that
672 many of the PDL calls do not need arguments to specify the size of the
673 the vectors and/or matrices being passed. This size parameters are
674 deduced from the size of the piddles, when possible. For now, the
675 following interfaces are affected:
676 plcont (f, kx, lx, ky, ly, clevel)
678 plfill (x, y)
679 plhist (data, datmin, datmax, nbin, oldwin)
680 plline (x, y)
681 plline3 (x, y, z)
682 plpoly3 (x, y, z, draw, ifcc)
683 plmesh (x, y, z, opt)
684 plmeshc (x, y, z, opt, clevel)
685 plot3d (x, y, z, opt, side)
686 plpoin (x, y, code)
687 plpoin3 (x, y, z, code)
688 plscmap1l (itype, intensity, coord1, coord2, coord3, rev)
689 plstyl (mark, space)
690 plsym (x, y, code)
