I consider Ruby to be my favorite programming language, and beyond learning the basics, at least what I've picked up from numerous Ruby on Rails projects and a few Ruby scripts, I've tried to learn from reading blogs like Gluttonous , O'Reilly Ruby , Ola Bini , and Polishing Ruby . I've also read in books like The Ruby Way . However, I haven't felt fully prepared when being interviewed about my Ruby skills. I was asked once if I knew

I needed to crop the 'main content' of an image for example if i had an image similar to this: alt text http://blstb.msn.com/i/8C/10F73EB7EE231B1EA8E65EFA7D69B.jpg the result should be an image with the msn content without the white margins(left& right). I search on the X axis for the first and last color change and on the Y axis the same thing. The problem is that traversing the image line by line takes a while..for an image that is 2000x1600px it takes up

nodejs test hyperledger composer v0.15 fails with Error: Card not found: PeerAdmin@hlfv1

However, I cannot find an SDK approach to create the necessary cards to run tests. The 'before' section of code up through v0.14 for my tests has looked like the following, which uses an embedded profile, creates a temporary instance of the network and runs the tests: describe('Finance Network', () => { // let adminConnection; let businessNetworkConnection; before(() => { BrowserFS.initialize(new BrowserFS.FileSystem

How to set NetworkX edge labels offset? (to avoid label overlap)

匿名 (未验证) 提交于 2019-12-03 02:30:02
可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I am trying to add edge labels for a graph. It all works well, only problem is when the two edges intersect - I only see one of the labels as they happen to overlap. As you can see the hphob-alpha label is shown but the polarity-beta label is not shown (my guess is that it is right under the previously mentioned). I could not find any documentation on how to re-position the labels, any advice how to set some kind of offset to move the labels? Code used to generate the graph: try: import matplotlib.pyplot as plt except: raise import networkx

Can this be done with sankeyNetwork or any other function in the networkD3 package? 回答1: This is not technically supported, but you can achieve it like this... library(networkD3) library(htmlwidgets) links <- data.frame( src = c(0, 0, 1, 2), target = c(2, 3, 2, 4), value = 1, name = c("first", "second", "third", "fourth") ) nodes <- data.frame(name = c("one", "two", "three", "four",

So on XAxis I have XDate variable increased by .AddMilliseconds(heart_beat_time) and on YAxis heart_beat_time . When I use AxisType.Date it's pretty good. I can change Min , Max and other related values, but when I change to AxisType.DateAsOrdinal I can not see points nor labels. During some debugging it has showed up that Zedgraph does paint the points and labels, but there are very large gaps between consecutive ones
