Multiple R treemaps on a single page with scaling

由 浪尽此生 提交于 2019-12-23 03:11:01
问题 I'm trying to put multiple treemaps on a single page. Each tree map is for a subset of the data and it would be useful to see them all at once. The following code creates a treemap for each subset but they each are on their own page. Question 1) Is there a way to put all of the treemaps on one page? Question 2) Is there a way to scale the overall size each treemap making some larger and some smaller? library(treemap) library(plyr) numSubsets = sapply(df[myIndexColumn], function(x) length

Google visualization not working with local file

问题 I'm working with a treemap, but the scale is coming out black. (related question: Google TreeMap fill value set to _ABSTRACT_RENDERER_ID_1). After reading that I was able to track down the problem to the code that google generates. It looks like the definitions are being declared correctly, but then the url to them looks like maybe doesn't work with local files. Perhaps because I'm working with a local file, see below: url(file:///D:/... ) <defs> <linearGradient gradientUnits="userSpaceOnUse"

d3.js - Treemap where parent's value is greater than sum of its children

由 只谈情不闲聊 提交于 2019-12-23 02:43:11
问题 I am trying to use d3.js to display a treemap where a parent's value may be greater than the sum of its children. For example, say I am visualizing lines of code in a namespace hierarchy. Namespace B and C are children of A and are 1 line each. Namespace A is 3 lines - 1 line for B and C and 1 line for itself. Thus B and C alone do not dictate the size of A. I want to display this property on the treemap. In particular, the parent should be a rectangle on top of the children rectangles whose

Spring Data JPA 自动建表字段顺序优化

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> JPA 自动建表字段顺序优化 1、表字段顺序和实体类定义字段顺序一致 原理：复制一个 hibernate 包下的 PropertyContainer 类，修改其中 persistentAttributeMap 的类型，TreeMap 修改为有序的 LinkedHashMap，在下次类加载时，会优先加载我们定义的类。 代码片段 2、自定义继承类字段顺序 原理同上就不说了。 一般我们的实体类会继承一个父类，父类中有 id，createTime，createUser，...，deleteFlag等字段。但是又不想让这些字段都在表字段最前边，或者说 id 在最前边就好了，其他字段放最后边就行。 打断点，跟代码，找到了 InheritanceState，同样覆写下 修改前：id，createTime，createUser，...，deleteFlag，其他字段 修改后：id，其他字段，createTime，createUser，...，deleteFlag if (elements.size() > 6 && "id".equals(elements.get(0).getPropertyName()) && "deleteFlag".equals(elements.get(5).getPropertyName())) {

While sorting the map based on value, some values are missing. What causes this weird behaviour?

问题 I am trying to sort a map based on word frequency (i.e., based on value). For that I have overridden comparator and passed to TreeMap , but I am getting this weird output. public class WordFrequency { public static String sentence = "one three two two three three four four four"; public static Map<String, Integer> map; public static void main(String[] args) { map = new HashMap<>(); String[] words = sentence.split("\\s"); for (String word : words) { Integer count = map.get(word); if (count ==

问题 I'm trying to sort a map in java by date key using TreeMap. Here's my code public static void sort() { BufferedReader br; String line; String[] data; Date date ; DateFormat df = new SimpleDateFormat("dd-mm-YYY"); Map<Date,String> map = new TreeMap<Date,String>(); try { br = new BufferedReader(new FileReader( "/home/user/Desktop/train/2013-training_set.txt")); int i=0; while ((line = br.readLine()) != null) { ++i; data = line.split(":"); map.put(df.parse(data[1]), line); } System.out.println

Not thread safe methods of CuncurrentSkipListMap in Java

由 我与影子孤独终老i 提交于 2019-12-20 05:43:08
问题 In my Java project I need to use TreeMap in multihreaded way. I found that ConcurrentSkipListMap is what that I need but some methods are not thread safe. One of them - containsKey(Object key). What is a typical solution for using this methods in multhreded way? In my program I need put key that will not replace old and if it's impossible I will be putting another key while will not get unique key. What construction should use instead containsKey as i can't lost information? 回答1: If you are

Obtaining key associated with corresponding maximum value in a Map(TreeMap/HashMap)

Migrating Java TreeMap code to Scala?

由 你离开我真会死。 提交于 2019-12-18 19:00:08
问题 I am migrating my Java code base to pure Scala and I am stuck on this one piece of code. I have an implementation of an IntervalMap i.e. a data structures that let's you efficiently map ranges [from,to] to values where the set , delete and get operations are all O(log n) (slightly different from an IntervalTree or a SegmentTree). This code uses Java's java.util.TreeMaps and while migrating to Scala, I ran into 2 big issues: Scala has no mutable.TreeMap - I decided to go around it by using

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 2 years ago . I'm interested in drawing a treemap: What is the easiest way to make one in Python? Is there a library that could produce such a graphic, given the proper input data? 回答1: The SciPy cookbook includes an example using matplotlib, but without labels.
