Plot Error Bars Idl


RGB_TABLE The number of the predefined IDL color table, or a 3 x 256 or 256 x 3 byte array containing color values to use for vertex colors. Keywords WIDTH The width of the error bars. The default value is [255, 255, 255] (white). Set this property to a scalar value to remove the background color. have a peek here

SYM_OBJECT Set this property equal to an object reference to be used for the plotting symbol. COLOR Set this property to a string or RGB vector that specifies the color of the plot line. Tip: If you want your graphic to share the same axes as an existing graphic, you should use the OVERPLOT keyword instead. Landsman Jan 1999 Handle NSUM keyword correctly W. http://www.harrisgeospatial.com/docs/ERRPLOT_Procedure.html

Fanning Last Updated 10 December 2013 IDL Reference Guide: Procedures and Functions ERRPLOT Syntax | Arguments | Keywords | Examples | Version History | See Also The ERRPLOT procedure plots If you want to create a smaller graphics window, you can use the NO_TOOLBAR keyword. The valid values are: (0) Nice range. Its source code can be found in the file errplot.pro in the lib subdirectory of the IDL distribution.

The default value is “Helvetica”. LOCATION Set this keyword to a two-element vector [X offset, Y offset] giving the window's screen offset in pixels. BUFFER Set this keyword to 1 to direct the graphics to an off-screen buffer instead of creating a window. Idl Horizontal Error Bars The default is 1.

POSITION Set this property to a four-element vector that determines the position of the graphic within the window. If only three parameters are input, they will be taken as X, Y and YERR, respectively. Added the following methods: Delete, GetData, GetValueAtLocation, MapForward, MapInverse, SetData. 8.2 Added AXES, BACKGROUND_COLOR, BACKGROUND_TRANSPARENCY, CLIP properties. 8.2.1 Added ANTIALIAS property. 8.2.2 Change POSITION from a keyword to a property. 8.2.3 http://idlastro.gsfc.nasa.gov/ftp/pro/plot/oploterror.pro The repeat indicates the number of times that individual bits in the bitmask should be repeated. (That is, if three consecutive 0’s appear in the bitmask and the value of repeat

Note: If the BACKGROUND_COLOR property is changed, and the current background transparency is 100, then the BACKGROUND_TRANSPARENCY will be automatically set to 0 (opaque) so that you can see the new Psym Idl For example, to create a plot with a solid red line of thickness 2, using the '+' symbol to mark data points, you would use the following: p = ERRORPLOT(data, '-r2+') If this property is not set then the symbol fill color will match the SYM_COLOR. This is useful if you want to later add another graphic that does have axes, and you want the two visualizations to be aligned properly.

Landsman, July 1995 Remove spurious call to PLOT_KEYWORDS W. http://idlastro.gsfc.nasa.gov/ftp/pro/plot/ploterror.pro This information is not subject to the controls of the International Traffic in Arms Regulations (ITAR) or the Export Administration Regulations (EAR). Idl Oploterr TRANSPARENCY The percent transparency of the lines. Oploterror Idl Default for all graphics except Image, Barplot, and Map. (1) Force the exact data range.

After creation the TITLE property may be used to retrieve a reference to the title text object, and the TEXT properties may be used to modify the title object. navigate here The bitmask should be specified as a 16-bit hexadecimal value. FONT_COLOR Set this property to a string or RGB vector that specifies the color of the title and axes (if present). See Linestyle Values for additional options. Idl Errplot

HIDE Set to 1 to hide the crosshair, 0 to show. ERRORBAR_COLOR Set this property to a string or RGB vector that specifies the color for the error bar. Format A string that sets line and symbol format properties using short tokens to represent color, symbol, linestyle, and thickness values. Check This Out CURRENT Set this keyword to create the graphic in the current window with a new set of axes.

The first dimension ncol is the number of columns in the grid, nrow is the number of rows, and index is the grid position at which to place the graphic (starting Idl Cgplot Landsman, August 1995 OPLOT more than 32767 error bars W. OPLOT keywords ] Input Parameters X = array of abcissae, any datatype except string Y = array of Y values, any datatype except string XERR = array of error bar values

Its source code can be found in the file errplot.pro in the lib subdirectory of the IDL distribution.

Training Want to learn from the experts? Note: When you retrieve the COLOR property, the returned value will always be a three-element RGB vector, regardless of how the color was initially specified. FILL_BACKGROUND A value of 1 fills the area under the plot. Idl Plot Linestyle For example, for a plot visualization: p = PLOT(/TEST) ax = p.AXES ax[0].TITLE = 'X axis' ax[1].TITLE = 'Y axis' ax[2].HIDE = 1 ; hide top X axis ax[3].HIDE = 1

If no current window exists, then this keyword is ignored and a new window is created.

ERRTHICK = the thickness of the error bar lines. For other graphics this property is ignored. Landsman November 1993 Add ERRCOLOR, use _EXTRA keyword, W. FONT_SIZE Set this property equal to an integer specifying the font size for the title and axes (if present).
