The problem of the graph, if each point is an even number of degrees, is the Euler loop, and for a point only two cases, odd and even, then the odd pair of points with a edge right for the original two points of the shortest value of the edge is not goodNo-map China postman problem:The problem of the direction diagram, if each point in the degree and out of the same, then is the Euler circuit, and this situ

background color, In this way, the map shows a clear indication of the level of data levels in different provinces. Take a look at the sorted code: $ (function () {$.get ("json.php", function (JSON) {//Get data var/string2array (JSON);//convert array var flag; The var arr = new Array (),///defines the newly-defined, corresponding level for (Var i=0;i In the above code, use var FillColor = Colors[arr[i]], get the color value of the corresp

If you have used Baidu statistics or cnzz statistics, you should know that there is a map statistics in the background, and the colors of provinces with different visits are different. Today, I will lead you to develop such a case. Today, I want to introduce how to load data into maps in practical applications. Combined with examples, this article uses PHP + Mysql + jQuery to achieve the data statistics of each province on

The example of this article shares the HTML5 Canvas Province of China Map implementation method, for your reference, the specific contents are as follows 1. Data acquisitionMap needs provinces border coordinates, theoretically can use Baidu API every time to get data and drawings, but in order to increase efficiency, first of all coordinates are captured and stored in the database.New Province Data Array

An ipad project needs to select the province and city functions, initially designed to use pop-up text floating layer, later the boss felt not beautiful enough, let UE design as follows. This component can support dragging, zooming, and the selection of provinces and municipalities across the country. Because it is the company's code, so open source needs to be audited by the company, the current code has some performance issues, to follow the performance improvement and through the audit will b
