I want to create a plot using X Y coordinates
显示 更早的评论
I have 51 nodes that each one of them has X Y coordinates. I used the command: plot(x,y, 'd') but I would like the figure to show me the number of each node next to the diamond.For example the first node I'd like to have the number 1 next to it, the second the number 2 etc. Also I'd like the first node to be different shape or colour from the others. Do I have to use two different types of plot or it can be done in the same command? Thank you for your time.

Example: —
x = rand(1,5);
y = rand(1,5);
nrc = compose('%2d',1:numel(x)); % Coordinate Numbers (Cell Array)
cm = jet(numel(x)); % Use The ‘colormap’ Of Your Choice
figure
scatter(x, y, 75, cm, 'd', 'filled')
grid
text(x, y, nrc)

Changed from plot to scatter since it provides more options, especially with respect to colouring the points. There are a limited number of shapes, so I would just go with changing the colours. The sizes of the plotted points can chnage with the colours with scatter.

plot(x, y)
text(x, y, string(1:numel(x)))
Now scatter(x(:), y(:), Pointsize, C)
where C is a numel(x) by 3 color array in which you set the first row to be different from the others. You can also set the marker shape on the call.
Limitations:
- all of the markers for the same plot line must be the same color and shape (unless I am forgetting a recent change)
- all of the markers for a single scatter call must be the same shape
x=rand(10,1); y=rand(10,1);
n=numel(x);
plot( graph(1:n,1:n),'LineStyle','none','Marker','d','XData',x,'YData',y);

Hi Matt, can I get 95 percentile in this data? maybe a circle representing 95 percentile of this data?
for example, consider 100 nodes, which is represented by (x,y) coordinates. How can I locate 95 percentile of this data?
