我对绘制线图概念有疑问.任何人都可以解释这些坐标吗？
x1=5,x2=10,y1=10,y2=30
请解释每个属性及其代表的含义.另外,请给我一个关于垂直和水平画直线(如十字线)的想法.
我是d3.js图表的全新手,所以请帮助我.任何帮助,将不胜感激.
我想删除使用小于和大于条件的值,例如我的数组
138,124,128,126,140,113,102,128,136,110,134,132,130,132,132,104,116,135,120
所以现在我的最小值是120,最大值是130.我想从数组中删除所有剩余的元素.这可能在javascript中.
我是新手,所以任何帮助将不胜感激.

console.log("working");
$scope.scratchpad =Food.query();
$scope.deleteScratch = function (scratch,flag) {
if(flag === 0) { //Checks if Bulk delete or single delete
if(confirm("You Clicked DELETE !! Are you sure ?")) {
scratch.$delete(function() { //Single delete
window.location.href = 'http://localhost:1337';
});
}

window.location.href = 'http://localhost:1337';
});
}
}
$scope.emptyScratchpad = function () {

Stylesheets and Preprocessors
==============================
You can always bring in CSS files manually with `<link>` tags, or asynchronously
using a solution like AMD (RequireJS). Or, if you like, you can take advantage
of Sails' conventional asset pipeline (boilerplate Gruntfile).
By default, stylesheets from your `assets/styles` folder are included
here automatically (between STYLES and STYLES END). Both CSS (.css) and …我正在尝试将字符串转换为数字,即"09"
