This article mainly shows you "Matlab how to draw Sanji diagram", the content is easy to understand, clear, hope to help you solve your doubts, the following let the editor lead you to study and learn "Matlab how to draw Sanji diagram" this article.

This time, the main purpose is to share a function written by myself, which is used to draw a Sanji diagram, and the effect looks like this:

First explain how to use the function (sankey2). The complete code of the function is placed at the end of the blog.

Detailed usage 1 use example

Create a new m file and run the following code

List= {'a1jewelry recorder 1 precepts aura;' a2pr recorders 1pia clockwork; 'a3mechelons beacons 1pyrrons;' a3locywagons 0.5pyrrymes; 'b1primes;' b1mins; 'b2pmpl;' b1pcc1pmpl; 'c1pmpl;' c1pmpl; 'c2pmlc1pmc1pmc1pl; c3pmlmlmlmcc1pmc1pmc1pmcc1pmlmlmlmlmlccccc1pmlmlmlmlmlmcccclmlmlmlmlmlmlmlmcccclmlmlmlmlmccclmlmlm 'Aphrodite pencils 2 pencils BBs;' Balls pencils 1. 5 pr é cors BBs; 'Bones pr é cor 1.5 pr é cor BBs;' Bones pr é cor 1.5 pr é cors; C é cor pr é cors 3.5 pence BBs;} Axis ([0Jing 2je 0jue 1]) sankeyHdl=sankey2 ([], 'XLim', [0Jing 2],' YLim', [0Jing 1], 'PieceWidth',0.15,'List',List,'Color', [0.3 meme 0.3 meme 0.7])

2 input parameters

2.1 necessary input parameters

There are a total of four necessary parameters. The first is the flow table ('List'), which can be imported from excel or written directly in the cell array as shown below:

List= {'a1jewelry recorder 1 precepts aura;' a2pr recorders 1pia clockwork; 'a3mechelons beacons 1pyrrons;' a3locywagons 0.5pyrrymes; 'b1primes;' b1mins; 'b2pmpl;' b1pcc1pmpl; 'c1pmpl;' c1pmpl; 'c2pmlc1pmc1pmc1pl; c3pmlmlmlmcc1pmc1pmc1pmcc1pmlmlmlmlmlccccc1pmlmlmlmlmlmcccclmlmlmlmlmlmlmlmcccclmlmlmlmlmccclmlmlm 'Aphrodite pencils 2 pencils BBs;' Balls pencils 1. 5 pr é cors BBs; 'Bones pr é cor 1.5 pr é cor BBs;' Bones pr é cor 1.5 pr é cors; C é cor pr é cors 3.5 pence BBs;}

The other three parameters are the x-axis range ('xLim'), the y-axis range (' YLim'), and the first parameter of the function. To draw the axes of the image, you can write the first parameter [] or gca in the current window.

2.2 Modification parameters

There are mainly the following, which are replaced with default values when not written.

Color Square Color

EdgeColor Square Edge Color

FontSize font size

FontColor font color

PieceWidth square width

Distance from edge to edge of Margin Sanji graph

Proportion of Sep vertical whitespace to total square length

Where Color can be a matrix of nx3 size, and the range of values in the matrix is [0prime1], for example:

List= {'a1jewelry recorder 1 precepts aura;' a2pr recorders 1pia clockwork; 'a3mechelons beacons 1pyrrons;' a3locywagons 0.5pyrrymes; 'b1primes;' b1mins; 'b2pmpl;' b1pcc1pmpl; 'c1pmpl;' c1pmpl; 'c2pmlc1pmc1pmc1pl; c3pmlmlmlmcc1pmc1pmc1pmcc1pmlmlmlmlmlccccc1pmlmlmlmlmlmcccclmlmlmlmlmlmlmlmcccclmlmlmlmlmccclmlmlm 'Aphrodite pencils 2 pencils BBs;' Balls pencils 1. 5 pr é cors BBs; 'Bones pr é cor 1.5 pr é cor BBs;' Bones pr é cor 1.5 pr é cors; C é cor pr é cors 3.5 pence BBs;} Axis ([0Pol 2] ColorList= [0.4600 0.5400 0.4600 0.5400 0.6800 0.4600 0.4100 0.4900 0.3600 0.3800 0.5300 0.8400 0.4400 0.5900 0.8700 0.7900 0.9300 0.6500 0.6400 0.8400 0.8300 0.5600 0.5300 0.5700 0.7600 0.8100 0.4300 0.5600 0.8600 0.9700 0.7800 0.5900 0.6500 0.8900 0.9100 0.5300 0.9300 0.5600 0.2500] SankeyHdl=sankey2 ([], 'XLim', [0jue 2],' YLim', [0d1], 'PieceWidth',0.15,'List',List,'Color',colorList)

3 output

The output of the function is as follows:

NameList is the name of each element, block is the graphic object of each square, connect is the graphical object of each connection, and txt is the text object of each label. We can do the following:

The original properties of graphic objects and text objects can still be used (color, position, transparency, edge thickness, etc.)

Suppose we try to manipulate the object on the basis of the following code:

List= {'a1jewelry recorder 1 precepts aura;' a2pr recorders 1pia clockwork; 'a3mechelons beacons 1pyrrons;' a3locywagons 0.5pyrrymes; 'b1primes;' b1mins; 'b2pmpl;' b1pcc1pmpl; 'c1pmpl;' c1pmpl; 'c2pmlc1pmc1pmc1pl; c3pmlmlmlmcc1pmc1pmc1pmcc1pmlmlmlmlmlccccc1pmlmlmlmlmlmcccclmlmlmlmlmlmlmlmcccclmlmlmlmlmccclmlmlm 'apocryphal 2] sankeyHdl=sankey2 ([],' XLim', [0pr 2]) sankeyHdl=sankey2 ([], 'XLim', [0pr 2]],' YLim', [0pr 1], 'PieceWidth',0.15,'List',List,'Color',colorList)

Operation 1 changes the fourth square color to red

SankeyHdl.block (4). FaceColor= [0.8 dint 0.3 pr 0.3]

Operation 2 turns the first connection of the 10th square red

SankeyHdl.connect (10Jing 1). FaceColor= [0.8 Jing 0.3 pr 0.3]

Operation 3 enlarges the 11th label text

SankeyHdl.txt (11). FontSize=40
