’g:’, will produce a green dotted line with no symbol, use the format string.’r+ ’, will produce a set of red + symbols at every data point,Īrguments which are not needed can be left out.’gs-’, will produce a green solid line with squares at every data point,.We can combine this three to form a format string, for instance: linespec can be any of – solid, : dotted,.shape can be any of o circle, x x-mark, + plus, * star, s square, d diamond, v triangle (down), ^ triangle (up), triangle (right), p pentagram, h hexagram.

color can be any of b blue, g green, r red, c cyan, m magenta, y yellow, k black.Where xi and yi are vector of the same size and format i is a format string of the form color shape linespec. axis can also be used to tighten the axes to include only the minimum space required to express the data using the command axis tight.The axis can be changed by calling axis() where the z-variables are only allowed if the figure is 3D.AX will be a row vector of the form where zlow and zhigh are only included if the figure is 3D. To retrieve the current axis limits, enter AX = axis().axis, axis can be used to both get the axis limits and set the axis limits.xlabel, ylabel and zlabel produce text labels on the x, y and if present z axes respectively, standard.title,title of graph, title (’Figure Title’).legend,labels the various elements on a graph, legend(’Series 1’,’Series 2’).These four are the most important, there are many more. We explore now the basic functions of graphics in MATLAB.
