![]() ![]() See the property descriptions for more details. Use the AlphaDataMapping property to control how the objects interpret the alpha data values. ![]() Then, specify flat transparencyīy setting either the MarkerFaceAlpha or MarkerEdgeAlpha property to First, specify the transparency values by setting the AlphaData property to an array the same size as the Scatter plots - Specify a different transparency value for each Then, specify flat or interpolated transparency by setting the FaceAlpha and EdgeAlpha properties to either 'flat' or 'interp'. First, specify the transparency values by setting the FaceVertexAlphaData property to a column vector with length equal to either the number of faces (for flat transparency) or the number of vertices in the patch (for interpolated transparency). Additionally, you can specify whether to use flat or interpolated transparency across each face or edge. Patches - Specify a different transparency value for each face and edge. Syntax: rectangle (‘Position’, xstart, ystart, length, breadth) where xstart and ystart are x and y coordinates respectively of the left bottom vertex of the rectangle. First, specify the transparency values by setting the AlphaData property to an array the same size as the ZData property. In MATLAB, we can draw a rectangle by just using the built-in ‘rectangle’ function which takes arguments as its left bottom vertex’s position and length and breadth. Specify the values by setting the AlphaData property to an array the same size as the CData property.Ĭhart and primitive surfaces - Specify a different transparency value for each face and edge. Images - Specify a different transparency value for each image element. % Replace default input arguments by input values % Default alpha value for the cube's faces % Default coordinates of the origin point of the cube % * COLOR : 3-elements vector that defines the faces color of the cube % * ALPHA : scalar that defines the transparency of the cube faces (from 0 % * ORIGIN: 3-elements vector that defines the start point of the cube % * EDGES : 3-elements vector that defines the length of cube edges % PLOTCUBE(EDGES,ORIGIN,ALPHA,COLOR) displays a 3D-cube in the current axes % PLOTCUBE - Display a 3D-cube in the current axes Here is the 'plotcube' code in case the link to the original code by Oliver breaks someday: function plotcube(varargin) This would require changing the code somehow to update all the XYZ data. I believe this is from calling the 'patch' function multiple times.Ī better solution would be to vectorise to put all your points (vertices/faces/whatever) together in a single matrix first and then call the function only once (no 'for' loop). running this 'plotcube' function in a 'for' loop in MATLAB over thousands of blocks. for large models (many cubes) this is very slow to run.Į.g. Parameters: xy(float, float) The anchor point. xy would be the bottom right corner if the x-axis was inverted or if width was negative. (above) change the section in Olivers code, adding in the four extra lines of code as follows: (replace the whole cellfun section with this including the new 'EdgeAlpha' and 'EdgeColor' lines): % Set this value to whatever you want even a variable / matrixįor more info on 'patch' please see patch documentation. One may picture xy as the bottom left corner, but which corner xy is actually depends on the direction of the axis and the sign of width and height e.g. ![]() fixed edge colour, or a colour that changes with Z-value etc.) Change the colour of the lines (EdgeColor).Īll of these can be constants, or variables.Change the transparency of the edges (EdgeAlpha), and/or,.Change the transparency of the faces (FaceAlpha), and/or,.The advantage of this solution is that you can: I understand this is a late reply but it is still valid in case anyone else is looking at doing the same thing.Īssuming you are plotting cubes (/their edges), an alternative to the answers already provided is to use the 'plotcube' code from Oliver: This table shows the difference between an opaque and semitransparent surface. Add transparency to graphics objects to customize the look of your charts or reveal details about an object that are otherwise hidden. X2(end+1,:,:) = NaN Y2(end+1,:,:) = NaN Z2(end+1,:,:) = NaN The transparency of a graphics object determines the degree to which you can see through it. It has the advantage that it creates a single graphic object: %# these don't all have to be the same ![]()
