Plotting Routines

---

List of Routines

• ADD_LABELS Add labels to an axis. Ticks are not added, so it is recommended
• ADD_TITLE Add a title to a plot. Designed to create a single title for an
• BEGPLOT Redirect plotting to the 'PS' device. See also ENDPLOT.
• DCENTER Center up the display
• DEFSYMBOLS Define symbols in true-type and vector type fonts. System variables
• DISPLAY_EXISTS Test if there is an X display. Works on *nix systems with the sh shell.
• ENDPLOT Closes and saves the current plotfile and returns to 'X'. See also BEGPLOT.
• ERRFILL Fill in the region x, y, y+/-yerr, which is the allowed range around x,y
• HISTOGRAM_POINTS Return as set of points which when plotted show a histogram representation
• IMPLOT_SETUP Given an image, generate position vectors and xrange/yrange vectors which
• LOGLABELS Generate nice labels for a log plot.
• MAKE_RAINBOW Return a set of N colors equally spaced along the rainbow. By default
• MARKSTRUCT_COPY_DEFAULTS GNU General Public License for more details.
• MARKSTRUCT_EXTRACT GNU General Public License for more details.
• MARKXY Mark the specified x,y point on the current device using one of the
• MULTIPLOT
• PLOT_BOX Plot a box with input set of coords.
• PLOT_CROSS Plot a cross with input size and center.
• PLOT_ELLIPSE Draw an ellipse on the current graphics device.
• PLOT_NE_ARROWS Plot a north and east arrow, with tails back to
• PLOTH histogram first and displays that as an image with tvim2
• PLOTHIST Plot the histogram of an array with the corresponding abcissa. This is an
• PLOTPOSITION Return the normalized plot position. If !p.position is set it is
• PPLOT A complete replacement for plot and ploterr that allows plotting of error bars in x and y as well as a user defined axis ratio.
• PSLANDFIX Fix the upside-down landscape that IDL generates.
• PSLAYOUT Set up the system variable !PSLAYOUT which contains information for
• PUT_CLR_SCL
• RAINBOW_RGB Produce rgb colors based on hue. Wrapper for COLOR_CONVERT so the
• RDIS Wrapper for tvim2. One can zoom, rescale, flip across x or y, or
• RDIS_SETUP Set up a parameter structure for rdis
• RDIS_ZOOM
• RGBVIEW Create and display a RGB image from red, green, and blue input images.
• SETFONT Set the font. Currently only supports vector fonts, for which it is
• SETUPPLOT Set up default plotting parameters. Parameters are taken from
• SIMPCTABLE Define a set of colors for plotting. If the display is 8-bit, a color
• TEXTOIDL Translate all occurences of one substring to another.
• TVASINH Display an input image using an asinh stretch (Lupton, et al...)
• TVIM2 Display an image.
• TVIM2_SCL View a peice of an image and retain the coordinates of the original image
