For Plot graphics, if SNAP is enabled, then only the X coordinate needs to be supplied. If any of the time units are utilized, then the tick values are interpreted as Julian date/time values.

BACKGROUND_TRANSPARENCY Set this property to an integer between 0 and 100 giving the percent transparency of the background color. NO_TOOLBAR By default the graphics window will have a toolbar containing some common tools such as Print and Save. I want error bars in both the X and Y directions. Latest from Exelis VISManage Vegetation Encroachment and Utility Assets Efficiently and Programmatically Geospatial Analytics in the Cloud with ENVI and Amazon Web Services | Recorded Webinar The only thing limiting us http://www.harrisgeospatial.com/docs/ERRPLOT_Procedure.html
CURRENT Set this keyword to create the graphic in the current window with a new set of axes. Tip: If you want your graphic to have a new set of axes, you should use the CURRENT keyword instead. If no current window exists, then this keyword is ignored and a new window is created. AXES (Get Only) This property retrieves an array that contains all of the AXIS objects within the visualization.
The default value is [128,128,128] (gray). A popular data analysis and visualization programming environment, IDL is used worldwide by scientists and engineers in fields as diverse as the physical sciences, medical physics, and engineering test and analysis. See the LINESTYLE property below for the list of allowed values. Idl Errplot NODATA Set this keyword to 1 to create the graphic, but without any data attached to it.
WIDGETS By default, when running from the IDL Workbench, the graphics window will use the native widgets for your platform. Use the scalar value 0 to not draw X error bars. The title is displayed in the window's title bar. http://www.harrisgeospatial.com/docs/ERRORPLOT.html While only modest prior programming experience is assumed, readers with experience in any procedural language will quickly translate their skills to IDL, learning the best programming practices for this new environment.
The default is 0.5. [XYZ]TEXT_COLOR A string or RGB vector containing the axis text color. [XYZ]TEXT_ORIENTATION The angle (in degrees) of the tick mark labels.

The coordinates [X1, Y1, X2, Y2] define the lower left and upper right corners of the graphic. You can set the following properties on the axes: Property Description [XYZ]COLOR A string or RGB vector containing the axis color. [XYZ]GRIDSTYLE A string, integer, or 2-element vector giving the linestyle
LINESTYLE An integer or string giving the line style. http://idlastro.gsfc.nasa.gov/ftp/pro/plot/ploterror.pro Valid values are: null (the default, signified by empty quotes), Years, Months, Days, Hours, Minutes, Seconds, Time, exponent for exponential notation, or scientific for scientific notation. Idl Oploterr Since the axes are in the middle, decrease the margins so the graphic almost fills the window. Ploterror Idl NAME A string that specifies the name of the graphic.
The default value is [0, 0, 0] (black). his comment is here If the argument is a vector, each value will be used as both a negative and positive error and the error bar will be symmetric about the plot vertex. The margins will be adjusted to leave space for the axes. If you want to create a smaller graphics window, you can use the NO_TOOLBAR keyword. Oploterror Idl
Low A vector of lower estimates, equal to data - error. He presents concise information on how to develop IDL programmers that are well structured, reliable, and efficient. The default value is "black". this contact form The default is 50.
This property is ignored if FILL_BACKGROUND is not set. Psym Idl Set this keyword to instead use IDL widgets for the graphics window. Examples To plot symmetrical error bars where Y is a vector of data values and ERR is a symmetrical error estimate, enter: ; Plot data: PLOT, Y ; Overplot error
Use the VERT_COLORS property to specify indices that select colors from the values specified with RGB_TABLE. A thickness of 0 displays a thin hairline. If you want to create a smaller graphics window, you can use the NO_TOOLBAR keyword. Idl Cgplot 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.
The default is 1. Social IntelliEarth Solutions Geospatial Products Custom Services IntelliEarth Marketplace Industries Defense & Intelligence Environmental Monitoring Academic Learn Videos Blogs Events & Webinars Training Case Studies Whitepapers Resources Support Forums Help Articles X only needs to be provided if the abscissa values are not the same as the index numbers of the plotted points. navigate here Default for Image, Barplot, and Map. (2) Pad the axes slightly beyond the nice range. (3) Pad the axes slightly beyond the exact data range.
Social IntelliEarth Solutions Geospatial Products Custom Services IntelliEarth Marketplace Industries Defense & Intelligence Environmental Monitoring Academic Learn Videos Blogs Events & Webinars Training Case Studies Whitepapers Resources Support Forums Help Articles The default is 1% of plot width. 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. You can also add Greek letters and mathematical symbols using a TeX-like syntax.
SYMBOL A string giving the symbol name. The two graphics items will then share the same set of axes. Examples To plot symmetrical error bars where Y is a vector of data values and ERR is a symmetrical error estimate, enter: ; Plot data: PLOT, Y ; Overplot error If STYLE is currently "None", then setting the LOCATION will automatically set the STYLE to "Manual".
Gumley is a researcher at the Space Science and Engineering Center at the University of Wisconsin-Madison. The default value is 16 points. If two elements are provided, the center of the graphic will be translated to that position. A thickness of 0 displays a thin hairline.
