问题 I want to generate something like this - the alignment of the nodes is the important thing, not the angle of the edges: +--------------+ | | +--------------+ | | V V +-----+ +-----+ <--- alignment at top | | | | | |->| | | | | | +-----+ | | | | | V | | +-----+ | | | | | | | |->| | | | | | +-----+ +-----+ <--- alignment at bottom | | V V +--------------+ | | +--------------+ The best I've been able to come up with is to stick the two left nodes into a cluster subgraph with a white (=>

问题 I've created a tree dump how described here: How can I dump an abstract syntax tree generated by gcc into a .dot file? for this dummy script: int fact(int n) { if (n<=1) { return 1; } return n * fact(n-1); } int main(void) { int a = 4; int res = fact(a); return res; } And the image what I've got: As I know gcc is not the best way to learn AST representation. But anyway it would be nice to understand what image's content means. Especially what % sign here means and a FREQ:0 statement? 回答1: The

问题 when working on ggplot()+geom_dotplot(), I wonder how to change the filled dot to the filled square 回答1: Welcome to stackoverflow. This is a total hack, but it will do what you want # plot just the dotplot p <- ggplot(mtcars, aes(x = mpg)) + geom_dotplot(binwidth = 1.5, dotsize = 1) + ylim(-0.1, 1.1) # this is the "instructions" of the plot gpb <- ggplot_build(p) # gpb$data is a list, you need to use the first element gpb$data[[1]] %>% ggplot(aes(x, stackpos/max(stackpos))) + geom_point(shape

问题 I am calling Graphviz from Java application using the Graphviz.java API and save the output graph to PDF file. I need to label some nodes with math subscripts and accents (for example $a_1$ or $\hat{a}$ in latex). I can survive with subscripts only. is there anyway to do it? is this because of the API i'm using or I am missing something here. I have tried b [label=<x<SUB>1</SUB>>]; but it doesn't work (though symbols like a [ label=<α>]; work and show up in the output file). 回答1: According to
