bmp format, yes, but when I change the resolution the output changes from my pretty figure with transparency, etc. Next week I will describe how we can customize plot line markers in ways that you never thought possible.
#Matlab 2014a plot cycle through colors update
Of course, we could always update the line’s fully-documented MarkerSize, MarkerFaceColor and MarkerEdgeColor properties, in addition to the undocumented customizations above. As far as I know, this cannot be set separately for each marker – they are all updated together. This is important for transparent lines, since it controls the brightness of the markers: “on top” (in front) they appear brighter. Therefore, the markers are only visible when the surrounding pixels are less opaque (i.e., lighter).Īs a related customization, we can control whether the markers appear “on top of” (in front of) the line or “beneath” it by updating the Edge.Layer property from ‘middle’ to ‘front’ (there is also ‘back’, but I guess you won’t typically use it). Since the lines are wide, the markers are surrounded by pixels of the same color. This is because the markers have the same color as the lines in today’s example. Note how the markers are clearly seen in the transparent lines but not the opaque ones. (Type " warning off MATLAB:gui:array:InvalidArrayShape" to suppress this warning.) Markers
Warning: Error creating or updating LineStrip So, for example, let’s modify the middle (30%-transparent) red line to something more colorful: (the data values themselves are kept as a 3xN matrix of single values in Edge.VertexData). Then we can modify Edge.ColorData from being a 4×1 array of uint8 (value of 255 corresponding to a color value of 1.0), to being a 4xN matrix, where N is the number of data points specified for the line, such that each data point along the line will get its own unique RGB or RGBA value. The tricky part is to change the Edge.ColorBinding value from its default value of ‘object’ to ‘interpolated’ (there are also ‘discrete’ and ‘none’). If anyone finds a documented reference anywhere, please let me know – perhaps I simply missed it.

In some rare cases (e.g., for patch objects) Matlab has separate Alpha properties that are fully documented, but in any case nowhere have I seen documented that we can directly set the alpha value in the color property, especially for objects (such as plot lines) that do not officially support transparency. This Alpha element is not documented anywhere as being acceptable, but appears to be supported almost universally in HG2 wherever a color element can be specified. So, for example, means a 70%-transparent red. In other words, color in HG2 can still be specified as an RGB triplet (e.g., to symbolize bright red), but also via a 4-element quadruplet RGBA, where the 4th element (Alpha) signifies the opacity level (0.0=fully transparent, 0.5=semi-transparent, 1.0=opaque). Producing this, while this changes the color order to MATLAB's previous default co = [ 0 0 1.In the past few weeks, I discussed the new HG2 axes Backdrop and Baseline properties with their associated ability to specify the transparency level using a fourth (undocumented) element in their Color. This uses the default R2015 color order x = linspace(0,4*pi)

Multiple lines in the same plot should then cycle through the RGB triplets specified in co.Įdit: Reading your post again, it seems you've tried this, so I tested it myself to show you it works and give you some sample code to look at. What you want here is set(groot,'defaultAxesColorOrder',co), as shown here: You're actually trying to change the default 'LineColor' cycle. If you want to use plot handles, I think colormap(handle, name) is what you're looking for, though I've never used it personally.Įdit: On second thought, I think I completely misinterpreted your question. % as the default colormap (in R2015 at least) As in sphere(10) % Creates a sphere surface plot using parula Assuming I'm understanding correctly what you're trying to do, you should be able to do colormap name.
