Below are the older, original graphics procedures for IDL , called "Direct Graphics."

ANNOTATE Procedure - Starts IDL widget used to interactively annotate images and plots with text and drawings.

ARROW Procedure - Draws line with an arrow head.

AXIS Procedure - Draws an axis of the specified type and scale at a given position.

BAR_PLOT Procedure - Creates a bar graph.

BOX_CURSOR Procedure - Emulates operation of a variable-sized box cursor.

CONVERT_COORD - Transforms coordinates to and from the coordinate systems supported by IDL.

CONTOUR Procedure - Draws a contour plot.

CROSSP - Sets the various system variables required to define a coordinate system and a 3-D view.

CURSOR Procedure - Reads position of the interactive graphics cursor.

CVTTOBM - Creates a bitmap byte array for a button label.

DEFROI - Defines an irregular region of interest of an image using the image display system and the cursor and mouse.

DEVICE Procedure - Sets to plot in device coordinates.

DRAW_ROI Procedure - Draws a region or group of regions to the current Direct Graphics device.

EMPTY Procedure - Empties the graphics output buffer.

ERASE Procedure - Erases the screen of the current graphics device, or starts a new page if the device is a printer.

ERRPLOT Procedure - Plots error bars over a previously drawn plot.

FLICK Procedure - Causes the display to flicker between two output images at a given rate.

FORMAT_AXIS_VALUES - Formats numbers as strings for use as axis values.

IMAGE_STATISTICS - Overlays an image with a contour plot.

LABEL_REGION - Consecutively labels all of the regions, or blobs, of a bi-level image with a unique region index.

LOADCT Procedure - Loads a pre-defined color table.

OPLOT Procedure - Plots vector data over a previously drawn plot.

OPLOTERR Procedure - Plots error bars over a previously drawn plot.

PLOT Procedure - Draws a graph of vector arguments.

PLOT_3DBOX Procedure - Plots a function of two variables (e.g., Z=f(X, Y)) inside a 3-D box.

PM_FILTER - Plots a 2-D field. N random points are picked, and from each point a path is traced along the field.

PLOTERR Procedure - plots individual data points with error bars.

PLOTS Procedure - Plots vectors and points.

POLAR_CONTOUR Procedure - Draws a contour plot from data in polar coordinates.

POLY - Interpolates a surface from polar coordinates (R, Theta, Z) to rectangular coordinates (X, Y, Z).

POLYFILL Procedure - Fills the interior of a polygon.

POLYSHADE Procedure - Creates a shaded-surface representation of one or more solids described by a set of polygons.

PROFILER - Extracts a profile from an image.

PS_SHOW_FONTS - Interactively examines image profiles.

PROJECT_VOL Procedure - Returns a two-dimensional image that is the projection of a 3-D volume of data onto a plane (similar to an X-ray).

RDPIX Procedure - Interactively displays the X position, Y position, and pixel value at the cursor.

SCALE3 Procedure - Sets up transformation and scaling parameters for basic 3-D viewing.

SCALE3D Procedure - Scales the 3-D unit cube (a cube with the length of each side equal to 1) into the viewing area.

SETENV - Sets the output device used by the IDL direct graphics procedures.

SET_SHADING Procedure - Modifies the light source shading parameters that affect the output of SHADE_SURF and POLYSHADE.

SHADE_SURF Procedure - Creates a shaded-surface representation of a regular or nearly-regular gridded surface.

SHADE_SURF_IRR Procedure - Creates a shaded-surface representation of an irregularly gridded elevation dataset.
Given a 3-D volume and a contour value, SHADE_VOLUME produces a list of vertices and polygons describing the contour surface.

SHADE_VOLUME Procedure - Given a 3-D volume and a contour value, produces a list of vertices and polygons describing the contour surface.

SHOW3 Procedure - Combines an image, a surface plot of the image data, and a contour plot of the images data in a single tri-level display.

SURFACE Procedure - draws a representation of a two-dimensional array projected into three dimensions, with hidden lines removed.

THREED Procedure - Plots a 2D array as a pseudo 3D plot.

TV Procedure - Displays an image.

TVCRS Procedure - Manipulates the image display cursor.

TVLCT Procedure - Loads a predefined color table or a color table from specified variables.

TVRD - Returns the contents of the specified rectangular portion of the current graphics window or device.

TVSCL Procedure - Scales and displays an image.

WRITE_BMP - Creates a window for the display of graphics or text.

WSET Procedure - Selects the current window.

WSHOW Procedure - Exposes or hides the designated window.

XYOUTS Procedure - Draws text on currently-selected graphics device.

ZOOM Procedure - Zooms portions of the display.

ZOOM_24 Procedure - Zooms portions of true-color (24-bit) display.
