Note that all these optional arguments exceptįlag can be customized through the axes entityĪs described before, the flag option deals with surfaceĮntity properties for mode (see surface_properties) and axes ,can be passed by a sequence of statements The optional arguments theta, alpha, leg ,flag, The surface entity properties (via tlist affectations)Īnd edited using color_flag option (see surface_properties). In this case positive values for colors mean The color argument must be a matrix of size nfxn giving the color nearĮach boundary of each facets. It is also possible to get interpolated color for facets. ![]() Id -colors(i) is used and the boundary of the facet is I and the boundary of the facet is drawn with current You can give a specific color for each facet by usingĬolors(i) is positive it gives the color of facet Through the surface entity properties (see surface_properties). Zf by multiple matrices assembled by rows as Plot3d(xf,yf,zf,)ĭraws a surface defined by a set of facets. X=1:m, y=1:n and =size(z) where m and n must be greater than 1. Plot3d(z) draws the parametric surface z=f(x,y) where If flag is missing,Įbox is not taken into account (by default ebox is missing).Īrgument acts on the data_bounds field that canĪlso be reset through the axes entity properties (see axes_properties). This argument isĬorresponding behaviour). It specifies the boundaries of the plot as the vector Through the axes entity properties (see axes_properties). Note that axes aspect can also be customized box=3:Ī box surrounding the surface is drawn andĪ box surrounding the surface is drawn, captions Only the axes behind the surface are drawn. Note that axes boundaries can be customized Rescales automatically 3d boxes with extremeĪspect ratios, the boundaries are specified by the valueĪspect ratios, the boundaries are computed using theģd isometric with box bounds given by optionalģd isometric bounds derived from the data, similarly toģd expanded isometric bounds with box bounds givenģd expanded isometric bounds derived from the The plot is made using the current 3D scaling (set Surface entity properties (see surface_properties). Note that the surface color treatment can be done modeĭrawn with current line style and color. Separator, for example (by default, axis have no label). ![]() String defining the labels for each axis with as a field Observation point (by default, alpha=35° and theta=45°). Real values giving in degree the spherical coordinates of the can be one of the following: theta,Īlpha ,leg,flag,ebox (see definition below). This represents a sequence of statements key1=value1, Of size (nf,n) giving color near each facet boundary (facet color is Each facetĬoordinates of the points of the ith facet are given respectively byĪ vector of size n giving the color of each facets or a matrix For more information on Scilab plots and Latex please read the article How to add Latex formatted text in a Scilab plot.Īfter running the Scilab instructions in a script file ( *.sce) or in the Scilab Console, we get the following graphical window.Row vectors of sizes n1 and n2 (x-axis and y-axisĬoordinates). Note that we used Latex notations for the y-axis. After, we use xlabel() and ylabel() to set the axes labels and title() for a title. Next instructions are setting the colour of the axis font and the thickness of the line. With gca() we read the current axes parameters and we assign them to the variable h1 for editing. The function y 1(x) is plotted with the instruction plot2d(). The functions are defined as: \[ \begin(x)=\sin(x)$","FontSize",3)įirst we create a colour variable c, which we are going to use as a setting for the axes and polyline (function curve). In this example we are going to plot 3 function y 1(x), y 2(2) and y 3(x) function of x, overlapping the curves, each with its own y-axis. This tutorial will teach you how to plot 2 or more y-axis plot in the same graphical window using Scilab. ![]() Scilab is very versatile at plotting multiple y-axes on the same graphical window. For this we need to plot several y-axes function of the same, common x-axis. When dealing with data we often need to compare different sets/series between themselves. ![]()
