Pyreverse complaining even after having Graphviz

问题 I want to be able to save the output in PNG and have installed Graphviz. Still it complains saying Graphviz is not installed: The output format 'output.png' is currently not available. Please install 'Graphviz' to have other output formats than 'dot' or 'vcg'. 回答1: As mentioned in comments by @KanwarG the solution is to install Graphvis from as a proper package and not using the python package found using pip. If using a mac then a solution is to used Homebrew. If you do not have Homebrew

Graphviz: Node in two subgraph

╄→尐↘猪︶ㄣ 提交于 2020-07-18 07:39:47
问题 I have a graph with different clusters. Basically I want to pair different nodes i.e. show somehow that different nodes have special relationship. So I decided to use clusters so that the nodes appear in a rectangle. The problem is that a node can be in relationship with more than one node i.e. it could be in different clusters. But I have not found out a way to insert a node in two clusters. I have the following code: digraph G {rankdir="LR"; node [fontname = "font-awesome"]; subgraph

How to enforce grid layout in graphviz/pydot?

ぃ、小莉子 提交于 2020-07-08 03:00:32
问题 tl;dr: How do I make graphviz stick to a grid layout of nodes? I'm trying to draw a "full causal graph" for a time series. This means that I have some graph with Units and Time indices repeating in the time direction. I want to draw the graph with Graphviz since it is programmatic. I don't know the number of Units, nor the number of Time steps. This will be varied as the project continues. I might also want to adjust colors, stroke widths etc programatically as a vizualisation of machine

Graphviz: xlabel position

懵懂的女人 提交于 2020-07-06 10:16:08
问题 I have nodes in my diagram with their xlabels positioned left above them. How can I change this position? I want the xlabels to be exactly next to the node itself. 回答1: xlp is the attribute you want, but it doesn't do anything. You can't change the position because xlp is "write only", which indicates that the attribute is used for output, and is not used or read by any of the layout programs. 来源: https://stackoverflow.com/questions/40959545/graphviz-xlabel-position

Graphviz does not display SVG images

筅森魡賤 提交于 2020-06-27 10:05:27
问题 I am trying to create a Graphviz chart with an SVG image embedded in a node, but the SVG image does not display whereas using a PNG image works fine. For example, I download this test image, and then use the following code digraph G { a [label=<<TABLE><TR><TD><IMG SRC="/full/path/Test.svg"/></TD></TR></TABLE>>]; a -> b; } Executing dot graph.gv -Tpdf -o graph.pdf Produces a PDF with a empty spot where Test.svg should be. Graphviz does not report any error message. I am doing this on macOS

How to increase distance between nodes in DiagrammeR R

最后都变了- 提交于 2020-06-17 05:12:31
问题 I have a nice graph with DiagrammeR in R studio, but the nodes are too clustered togather. I have searched everywhere but I cannot find a way of increasing the distance between them. Can I be shown? Here is my code: library(magrittr) library(DiagrammeR) # Create a simple NDF nodes <- create_nodes(nodes = c("Index", "Surveillance", "Intervention","Lost"), label = TRUE, fontsize=55, type = "lower", style = "filled", color = "aqua", shape = c("circle", "circle", "rectangle", "rectangle"), data =
