I’m stuck here: I do not know of any possibility to vary the marker sizes individually. (2) use individual marker sizes to encode a 4th variable (e.g. (1) use individual marker transparencies to encode a 3rd variable (e.g. One more question: in MATLAB, I frequently need to generate a 2D scatter plot with: Thank you very much for these very valuable tips! They really open up a plethora of charting options that come in very handy, in my case.ĭo you have any further details / documentation about ‘MarkerHandle’? For example, I am wondering about how to use the xxBinding properties how exactly do ‘object’, ‘interpolated’, ‘discrete’ and ‘none’ work? For example, bar charts have internal Face and Edge properties that correspond to internal objects that can be similarly modified: – other chart types have similar internal objects that can be customized. If you’re into experimentation, you might also try ‘colormapped’ and ‘texturemapped’. Throughout today, we’ve kept the default FaceColorType/EdgeColorType value of ‘truecolor’ (which is really the same as ‘truecoloralpha’ as far as I can tell, since both accept an alpha transparency value as the 4th color element). In fact, it opens up Matlab plots to a whole new spectrum of customizations that were more difficult (although not impossible) to achieve earlier. We can also use it to overlay meta-data information, such as buy/sell indications on a financial time-series plot. This can be useful for plotting comet trails, radar/sonar tracks, travel trajectories, etc. Matlab plot markers with color and transparency gradients > set(hMarkers,'FaceColorBinding','interpolated', 'FaceColorData',colorData) > set (hMarkers, 'FaceColorBinding', 'interpolated', 'FaceColorData',colorData ) > hMarkers.FaceColorData' % 4-element uint8 arrayĪs we can see, we can separately attach transparency values to the marker’s edges and/or faces. ![]() > hMarkers.EdgeColorData' % 4-element uint8 array > hMarkers = hLine.MarkerHandle % a .Marker object FaceColorData' % 4-element uint8 array ans = EdgeColorData' % 4-element uint8 array ans = ![]()
