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 Is there an easy way, to switch between two or more diagrams with a button? I would like, for example be able to switch between these two diagrams with a button instead of showing them one after the other. import matplotlib.pyplot as plt x_values = [1, 2, 3, 4, 5] y_values = [1, 4, 9, 16, 25] plt.bar(x_values, y_values) plt.show() x_values = [5, 4, 3, 2, 1] y_values = [1, 4, 9, 16, 25] plt.bar(x_values, y_values) plt.show() I know there are examples for this problem out there, but I simply

问题 I'm tasked with building a set of Architectural Diagrams to share with a third party. Most have been pretty familiar, but the request for an Enterprise Architectural Diagram has me a bit stuck. I'm not exactly sure what information this particular diagram is supposed to convey to the reader. 回答1: Neither UML nor SysML defines an Enterprise Architecture Diagram. It might be that there is a clear definition of this diagram type in some other modelling language or framework, but if so I am not

问题 This question is related to diagraming a software process. As an electrical engineer, much of the software I do is for embedded micro-controllers. In school, we learned to illustrate our algorithm using a flowchart. However, nowadays, many of my embedded projects are heavily interrupt-driven where the main process runs some basic algorithm a variety of interrupt sources provide its stimulus. So, my question is, what are some diagramming techniques that I can use to illustrate my process such

问题 On a big company, which diagrams (such as activity or class) are created before the development of a specific application? And you guys recommend this type of practice on small projects? Thanks 回答1: That is pretty open-ended and depends quite a bit on the type of development methodology the company is using. And, honestly, it depends on the expertise of the team, the type of system being developed, customer requirements, and many other factors as well. In my experience, you will typically see

问题 I want to use scale_colour_brewer() and scale_fill_brewer() to specify the fill or colours via the brewer palette: diagram <- diagram + scale_colour_brewer() + scale_fill_brewer() Nevertheless, I still want to set the legend label and its entries manually. I did so formerly via: diagram + scale_colour_manual(name="Cumulative Percentage", values=c("#d7191c","#fdae61","#000000","#abdda4","#2b83ba"), labels=c("GN","GN1","GN2","GN3","GN4")) How can I use the auto-palette feature, while still
