Graph flow chart of transition from states

阅读更多关于 Graph flow chart of transition from states

问题 I'm trying to find a way to graph something like this in R: It is a transition between states, I want the boxes to be equal to the population size and the arrows to indicate the size of the transition. I've looked at the Diagram package but it's flow charts seem too crude for this. Is there a better package that allows this? If 1 == FALSE: Is there some other software that is better suited? If 1 & 2 == FALSE: I guess the last resort is grid rectangles and bezier curved arrows, any ideas how

Sankey Diagrams in R?

阅读更多关于 Sankey Diagrams in R?

问题 I am trying to visualize my data flow with a Sankey Diagram in R. I found this blog post linking to an R script that produces a Sankey Diagram, unfortunately it's quite raw and somewhat limited (see below for sample code and data). Does anyone know of other scripts—or maybe even a package—that is more developed? My end goal is to visualize both data flow and percentages by relative size of diagram components, like in these examples of Sankey Diagrams. I posted a somewhat similar question on

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . I need to automatically construct flowcharts out of C++ code, ideally one flowchart per source file. Is there any tool (preferably C++/Python and either open-sourced or highly configurable - so I may change the look) that I can use to create flowcharts? 回答1: clang/llvm can generate graphviz dot files. Example:

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . I've never read COBOL in my life and have been tasked with rewriting the old COBOL code in a new language. Are there any free or free-to-try software packages out there that will generate a flow chart for a COBOL program? I've looked at "Visustin" and "Code Visual to Flowchart" Visustin blanks out part of the

What is the difference between a data flow diagram and a flow chart?

阅读更多关于 What is the difference between a data flow diagram and a flow chart?

问题 I want to know why we use Data Flow Diagrams instead of flow charts. 回答1: You should use whatever you like. The diagram is just a tool. Use whatever tool fits you and your problem best. I usually just use boxes and arrows and squiggles and circles and little stick figures and whatever else I think gets the point across to the viewer. In short it doesn't matter if you even use a standard diagraming standard. People are usually pretty good at understanding pictures. 回答2: A flow chart details

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last year . I need to incorporate a flowchart design surface into an app we're developing to allow users to create what are essentially workflows/schedules. I need to be able to create my own 'shapes', set custom properties on them and possibly have a bit of logic in there too (if, while etc). I know I need to take a look at

How to represent a recursive function with a Flow Chart?

阅读更多关于 How to represent a recursive function with a Flow Chart?

问题 I need to represent a recursive function on a flow chart. My problem is that I don't know how to indicate that the function may call itself over multiple elements at a time (think for example to a function which scans graphs). Someone has any suggestion? 回答1: In a flow chart, you don't normally add multiple invocations for things like loops, you would just indicate that the code may be repetitively called until a condition is met. So, for a recursive function, it would be similar - the base

I am currently developing an app using MEAN stack with Angular version 4. I have a requirement to create dynamic flowcharts. I want similar to what is available in http://fiddle.jshell.net/awolf2904/aw2e3ovz/ It is exactly matchingn my requirement. It is using Flowchart.js and Angular 1.X. Also Mermaid seems to be matching my requirement but onceagan support Angular 1.x. Could someone help me in this? As long as the libraries are not available as Angular packages you have to utilize it by defining a typing in your project: declare var flowchart:any This type definition makes the library

Making an editable flowchart in Qt/C++

阅读更多关于 Making an editable flowchart in Qt/C++

问题 I'm working on making a editable flowchart and I'm having a lot of issues conceptually with Qt. I've tried many different ways of implementing classes ranging from QTreeWidget , QTableWidget , and using just a bunch of easy QPushButtons . Ideally I'd like to have a setup where I can right click on each piece of the flow and edit it. In addition to having a drag and drop feature to rearrange the objects in the flow. Trying to find a class/group of classes I can use together to achieve this has

Generate dynamic flow-chart

阅读更多关于 Generate dynamic flow-chart

问题 We are looking for some code/component that can create a flow-chart (image) dynamically , preferably in .NET/C# (although a Silverlight/Flash-component that takes a XML/JSON-feed will also be fine). For example we have a (business) quote that goes through te following steps before it becomes final: Requested -> Pending -> Ready for revision -> Under revision -> Final And as an extra step there is the possibility to go from 'Under revision' back to 'Pending'. So the component/code should draw
