H.

Theme Copy h surf (peaks (50)) set (h,'edgecolor','none','facecolor'. I am a bit surprised by the way isoview acts on a surf plot. surf (peaks (20)) colormap summer shading interp Or, you can just set the color to be a boring, flat, greenish hue. Zmax=max(max(z1),max(z2)) //Absolut maximum of all data sets Scilab-users surf & isoview: bug or unexpected feature. If not specified, those properties are available for both Polyline and Fac3d objects (created respectively by plot or surf ) and, as previously said, they are applied to the new created objects (lines or surfaces). Zmin=min(min(z1),min(z2)) //Absolut minimum of all data sets Here is a complete list of the PropertyName you can specify (using plot or surf) and their available associated PropertyValue. And as a surface it has the cdata_mapping property, which can be changed from scaled to direct and scale the color matrix (which defines the color of each facet) according to the actual range used: x=-5:0.1:5 Please note, that surf generates a 3D plot, but you can rotate it to seem as a 2D plot.

color_flag = 3 // interpolated shading mode.I don't know how to do it with contourf, but if you can use surf instead, I have a suggestion. cdata_mapping = ' direct ' // default is ' scaled ' relative to the colormap e. Z initialisation Z = //simple surface surf ( Z ) // Note that X and Y are determined by Z dimensions //same surface with red face color and blue edges scf ( 2 ) // new figure number 2 surf ( Z, ' facecol ', ' red ', ' edgecol ', ' blu " ) // X and Y initialisation // NB: here, X has the same lines and Y the same columns X = Y = // example 1 scf ( 3 ) surf ( X, Y, Z ) //example 2 // As you can see, the grid is not necessary rectangular scf ( 4 ) X ( 1, 4 ) = - 1.5 Y ( 1, 4 ) = - 3.5 Z ( 1, 4 ) = - 2 surf ( X, Y, Z ) // example 3 // X and Y are vectors = > same behavior as sample 1 // With vectors, the grid is inevitably rectangular scf ( 5 ) // new figure number 5 X = Y = X surf ( X, Y, Z ) //LineSpec and GlobalProperty examples: xdel ( winsid ( ) ) // destroy all existing figures surf ( Z, Z + 5 ) // color array specified e = gce ( ) e. Note that all these properties can be (re-)set through the surfaceĮntity properties (see surface_properties). That you can set multiple properties : the face & edge color,Ĭolor data, color data mapping, marker color (foreground andīackground), the visibility, clipping and thickness of the edges of PropertyValue (which can be a string or an integer or.Īs well depending on the type of the PropertyName). It must always be a couple statement constituted of a stringĭefining the PropertyName, and its associated value This option may be used to specify how all the surfaces areĭrawn. Here is a brief description on how it works: GlobalProperty The GlobalProperty arguments sould be used to customize Vertices), the last row and column of C are ignored. When 'flat' (default mode) is enabled we use a colorįaceted representation (one color per patch).

Please note that the recommended version of Scilab is 2023.0.0. The FaceColor property sets the shading mode : it canīe 'interp' or 'flat' (default mode).
