treemap

问题 is there a color scale palette that can give sequential RAG color for a treemap. I tried "RgYlGn" but due to the range being less over 28 unique values, the colors come out as all Green or Yellow. What I want is the least value being red and median being yellow and max being green with a sequential color gradient from red to green 回答1: The function colorRampPalette might be useful to you. colorRampPalette(c("red", "yellow", "green")) 来源： https://stackoverflow.com/questions/34517031/red-amber

问题 I have a tree map with a following key value pair combination Map is declared as follows Map<String, List<Bean>> outputMap = new TreeMap<String,List<Bean>>(); Corresponding code will be for (String course_date : shiftSet) { Bean courseBean = null; boolean valueExists = false; for (Entry<String, List<Bean>> entry: courseMap.entrySet()){ valueExists = false; String studentDetail = entry.getKey(); String [] studentSet = StringUtils.getArray(studentDetail , ","); String studentId = studentSet[0];

问题 With Anychart 8.3+ I am using the TreeMap chart.listen('drillChange') listener to obtain a clicked element's information. Note: I needed to use e.current.get('name') as shown in an example, instead of e.currentTarget as per Treemap listen() documentation. However the getDrillDownPath() value seems to be one event-click behind. Why is this? chart.listen("drillChange", function(e){ // get the drilldown path and convert it to a string var text = printPath(chart.getDrilldownPath()); // set the

问题 I want to configure a Highcharts treemap so that if the datalabel is long enough to overflow the point bounds (as opposed to just the chart bounds), it is hidden. An example of the problem can be seen here: http://jsfiddle.net/atootspb/ I would like the final label ("Gggggg") not to display since it overflows its point's boundaries. I have tried experimenting with the dataLabels options including padding , overflow and crop , all to no avail. 回答1: This can't be done just by configuring

问题 Code: Map<Integer, HashSet<String>> test = new TreeMap<>(); test.put(1, new HashSet<>()); test.put(2, new HashSet<>()); test.put(3, new HashSet<>()); test.put(4, new HashSet<>()); test.get(1).add("1"); test.get(2).add("2"); test.get(3).add("2"); test.get(4).add("3, 33"); //get value of treemap and get rid of the duplicate by using distinct and printout //at the end test.values().stream().distinct().forEach(i -> System.out.println(i)); output: [1] [2] [3, 33] My question is how I can printout

问题 I am using a google tree map to render some data. I have a problem with showScale component. When the tree map renders, the showScale component is completely black when it should show a e gradient between minColor and maxColor. The fill attribute of the svg component is set as follows : fill="url(#_ABSTRACT_RENDERER_ID_1)" Can you explain what _ABSTRACT_RENDERER_ID_1 is ? 回答1: It will be either a gradient fill or a pattern fill. Somewhere else in the file - probably in a <defs> section - will

问题 I have a rather large text file (~4m lines) I'd like to parse and I'm looking for advice about a suitable data structure in which to store the data. The file contains lines like the following: Date Time Value 2011-11-30 09:00 10 2011-11-30 09:15 5 2011-12-01 12:42 14 2011-12-01 19:58 19 2011-12-01 02:03 12 I want to group the lines by date so my initial thought was to use a TreeMap<String, List<String>> to map the date to the rest of the line but is a TreeMap of List s a ridiculous thing to

问题 For representing most popular artists from EchoNest API, I've been trying to set-up Silverlight Toolkit's TreeMap using images, their TreeItemDefinition.ValueBinding being defined as the area of the image. While it mostly fills up the space when the image stretch is set to 'Fill' : When setting image stretch to 'Uniform' a lot of blank spaces remain : On this post, image carving is suggested : Treemapping with a given aspect ratio How can I know which images should be carved and at what

问题 As described in the answer to Double in HashMap, Doubles shouldn't be used in HashMaps because they are difficult to compare for equality. I believe my case is different, but I thought I'd ask to make sure since I didn't see anything about this. I'm going to have a series of double values associated with objects, and I want them to be sorted by the double values. Is TreeMap an appropriate solution? Would there be a better one? The double values are generated a bunch of math, so the likelihood
