This page is dedicated to specialized ways of controlling the look of contours, via shading, transparency (NEW in V6.1.0), color fill, line thicknesses, and dashed patterns.Three new resources were added in V6.1.0, allowing you to specify a color palette for filled contours (and whether to span that color palette), and controlling the opacity of color colors.cnFillPalette - allows you to specify a color palette for your filled contours. This can be a color map name, or an array of color indexed values, RGB values, or RGBA values.cnSpanFillPalette - a True/False resource allowing you to indicate whether the current fill palette should be fully spanned.cnFillOpacityF - a resource that allows you to SET the opacity of all colors in a contour plot.In addition, in V6.1.0, the cnFillColors resource can now be given an n x 4 array of RGBA values, allowing to specify the opacity of individual colors.Three other popular resources and a function include:gsnContourZeroLineThicknessF - a resource for setting the thickness of the zero contourgsnContourNegLineDashPattern - a resource for setting the dash pattern for negative contoursgsnContourPosLineDashPattern - a resource for setting the dash pattern for POSITIVE contoursgsn_contour_shade - a function for controlling the shading and filling of contoursThis page MENTIONS some older methods for doing shading and color fill, all of which have been superceded by gsn_contour_shade:ColorShadeLeGeContourColorNegDashZeroPosContourShadeLtContourShadeGtContourShadeLtGtContourShadeGeLeContourplease mark me brain mark list
