NhlFrame

Updates and clears the given workstation objects.

Prototype

	procedure NhlFrame (
		wks  : graphic   
	)

Arguments

An array of any dimensionality of NCL Workstation identifiers. The identifiers are ones returned either from calling gsn_open_wks or calling create to create a Workstation object.

Description

The NhlFrame procedure updates and then clears the Workstation object ids passed to it as elements of the array wks. If the parameter references objects that are not valid, error messages will be generated.

Note: this procedure is identical to the frame procedure, and we encourage the use of frame instead (saves having to type longer names and capital letters).

Examples

Example 1

begin
;
; Create workstation.
;
  wks = create "poly" xWorkstationClass defaultapp end create

;
; Create a data object.
;
  npts = 500
  x    = fspan(0,npts-1,npts)
  y    = 500.+ 0.9 * x * sin(0.031415926535898*x)

  dataid = create "data" coordArraysClass noparent
    "caYArray" : y
  end create

  xy = create "xy" xyPlotClass wks
    "xyCoordData" : dataid
  end create

  text1 = create "text1" textItemClass wks
    "txString"      : "This is a string at the top"
    "txFont"        : 22
    "txPosYF"       : 0.5
    "txPosYF"       : 0.9
    "txFontHeightF" : 0.03
  end create

  text2 = create "text1" textItemClass wks
    "txString"      : "This is a string at the bottom"
    "txFont"        : 22
    "txPosXF"       : 0.5
    "txPosYF"       : 0.1
    "txFontHeightF" : 0.03
  end create

  NhlDraw((/xy,text1,text2/))   ; could also use draw((/xy,text1,text2/))
  NhlFrame(wks)                 ; could also use frame(wks)
end
