Tip: If you want your graphic to share the same axes as an existing graphic, you should use the OVERPLOT keyword instead. Syntax ERRPLOT, [ X, ] Low, High [,WIDTH=value] Arguments X A vector containing the abscissa values at which the error bars are to be plotted. The valid values are: (0) Nice range. Error bars can also be created on plots using the ERR_* keywords available on the cgPlot command. have a peek here

However, it may be restricted from transfer to various embargoed countries under U.S. This keyword has no effect if the window is already created. The default is 1. [XYZ]TICKDIR Set to 1 to draw the tickmarks facing outwards. BUFFER Set this keyword to 1 to direct the graphics to an off-screen buffer instead of creating a window. http://www.harrisgeospatial.com/docs/ERRPLOT_Procedure.html

ERRORBAR_COLOR Set this property to a string or RGB vector that specifies the color for the error bar. If the argument is a vector, each value will be applied as both a negative and positive error and the error bar will be symmetric about the plot vertex. For Plot graphics, if SNAP is enabled, then only the X coordinate needs to be supplied. FILL_COLOR Set this property to a string or RGB vector that specifies the color for the filled area.

The default value is [128,128,128] (gray). CROSSHAIR (Get Only) Use this property to retrieve a reference to the Crosshair graphic. This argument is converted to double-precision floating-point before plotting. Idl Errplot Example The following lines create the plot shown at the right.

The default behavior is to plot the entire data range. Idl Ploterr COLOR Set this property to a string or RGB vector that specifies the color of the plot line. Landsman June 1998 Ignore !P.PSYM when drawing error bars W. For example, if NSKIP = 2 then every other error bar is plotted; if NSKIP=3 then every third error bar is plotted.

This is the default for images. 1 - Single X, Y (and Z if 3D) axes located at the minimum data value. Idl Horizontal Error Bars Note: You must still provide valid input arguments. This is the default for 2D graphics. 3 - Crosshair-style axes - located at the midpoint of each data dimension. If a 3 x N array of colors is provided, the colors are used directly and the color values provided with RGB_TABLE are ignored.

This argument is converted to double precision floating-point before plotting. http://www.idlcoyote.com/graphics_tips/yerrorbars.html SYM_TRANSPARENCY An integer between 0 and 100 that specifies the percent transparency of the symbols. Idl Oploterr TRANSPARENCY An integer between 0 and 100 that specifies the percent transparency of the plot line. Ploterror Idl X with both X and Y errors and no lines connecting the points IDL> oploterror, x, y, xerr, yerr, psym=3 (2) Like (1) but overplot only the Y errors bars and

The margins will be adjusted to leave space for the axes. navigate here The STYLE property may be used to automatically draw the crosshair, while the LOCATION property may be used to manually draw the crosshair. ERRCOLOR = scalar integer (0 - !D.N_TABLE) specifying the color to use for the error bars NSKIP = Positive Integer specifying the error bars to be plotted.

If you have a graphic in another window that is not currently selected, you can also set this keyword to that graphic's reference to overplot on top of that graphic. Use the returned reference to manipulate the graphic after creation by changing properties or calling methods.

[XYZ]SHOWTEXT Set to 1 to show text labels or 0 to hide the text labels. [XYZ]STYLE

The default value is 1, which places a symbol on every vertex.

Set HIDE to 0 to show the graphic. The default is 'dot'. I typically do plots in black on a white > background (so I can copy the image into documents, etc.), rendering the > error bars invisible. Idl Cgplot For Plot graphics the default behavior is to display the crosshair when a Mouse_Down event is received.

By default, margin values are expressed in normalized units ranging from 0.0 to 0.5. The title is displayed in the window's title bar. ANTIALIAS, ASPECT_RATIO, AXES, BACKGROUND_COLOR, BACKGROUND_TRANSPARENCY, CLIP, COLOR, CROSSHAIR, ERRORBAR_CAPSIZE, ERRORBAR_COLOR, ERRORBAR_LINESTYLE, ERRORBAR_THICK, FILL_BACKGROUND, FILL_COLOR, FILL_LEVEL, FILL_TRANSPARENCY, FONT_COLOR, FONT_NAME, FONT_SIZE, FONT_STYLE, HIDE, LINESTYLE, NAME, POSITION, RGB_TABLE, SYM_COLOR, SYM_FILLED, SYM_FILL_COLOR, SYM_INCREMENT, SYMBOL, SYM_SIZE, this contact form Buie, Lowell Obs., Feb 1998 Rename to OPLOTERROR W.

Landsman Jan 1999 Handle NSUM keyword correctly W. DEVICE Set this keyword if values are specified in device coordinates (pixels) for the MARGIN and POSITION keywords. (Normalized coordinates are the default for these keywords.) DIMENSIONS Set this keyword to Landsman Jan 2002 Fix Jan 2002 update to work with log plots W. SYM_FILLED Set this property to 1 to fill the symbols.

The default is 50. The ERRPLOT procedure plots error bars over a previously drawn plot. Xerror Either a vector or a 2 x N array of error values to be displayed as error bars for the X dimension of the plot. This approximation is meaningful only when the neighboring error bars have similar sizes. /LOBAR = if specified and non-zero, will draw only the -ERR error bars. /HIBAR = if specified and

y = [20.1, 19.9, 20.0, 20.0, 19.9, 20.0] yerror = [0.329, 0.186, 0.147, 0.086, 0.234, 0.196] x = INDGEN(6)+1 ; Create the plot p = ERRORPLOT(x, y, yerror, XRANGE=[0,7], $ The two graphics items will then share the same set of axes.
