Keyword Parameters


Keywords


        VMIN=vmn Minimum value of color bar parameter (def=0).
        VMAX=vmx Maximum value of color bar parameter (def=top).
        CMIN=cmn Color that represents vmn (def=0).
        CMAX=cmx Color that represents vmx (def=top).
          where top = !d.table_size-1.
        CCLIP=cc Actual max color index allowed (def=!d.table_size-1)
        /HORIZONTAL Colors vary horizontally (def).
        /VERTICAL Colors vary vertical.
        /BOTTOM Horizontal axis on bottom (def).
        /TOP Horizontal axis on top.
        /RIGHT Vertical axis on right (def).
        /LEFT Vertical axis on left.
        /AXES_ONLY Plot only the axes and labels, no bar image.
        COLOR=clr Color of axes and labels. Use 24 bit color
          value, may obtain from clr=tarclr(r,g,b,/c24).
        /KEEP_SCALING Keep color bar axes scaling on exit.
        LAST_IMAGE=z Return last color bar image.
        LAST_POS=pos Return last position used.
        LAST_XSAVE=xs Return last !x used.
        LAST_YSAVE=xs Return last !y used.
        LAST_PSAVE=xs Return last !p used.
          If any LAST_* keywords used then other keywords are ignored.
        XSAVE=xs, YSAVE=ys, PSAVE=ps returned original scaling.
          Use /KEEP to plot in cbar coordinates (x=[0,1],y=[vmn,vmx]).
          May then restore original scale: !x=xs & !y=ys & !p=ps
        Plus all keywords accepted by PLOT.

Notes


      Notes: Bar is positioned using the POSITION keyword.
        To display a title use TITLE and so on.
        Almost the same as cbar with a few added options.
