將按鈕添加到圖表 - svg

Question

我想使用JS庫開發交互式圖表。在此圖表中我想有按鈕（在圖表內），以這種方式（紅色）：

我想也改變線路類型（虛線例如）。

我試過Morris.js，但這個庫不允許我做我想做的事。

有沒有其他的庫可以用來代替？

Answer 1

這可能與Morris.js，但你需要添加一些代碼莫里斯（最新版本0.5.1）畫虛線：

擴展莫里斯，添加一個名爲lineStyle參數，並在這個參數設置爲. Morris區域配置。

爲raphael.js線條樣式的可能值見this answer：

["", "-", ".", "-.", "-..", ". ", "- ", "--", "- .", "--.", "--.."] 

在mouseover解決方案：

(function() { 
 
    var $, MyMorris; 
 

 
    MyMorris = window.MyMorris = {}; 
 
    $ = jQuery; 
 

 
    MyMorris = Object.create(Morris); 
 

 
    MyMorris.Grid.prototype.gridDefaults["lineStyle"] = ""; 
 
    
 
    MyMorris.Line.prototype.drawLinePath = function(path, lineColor, lineIndex) { 
 
     return this.raphael.path(path).attr('stroke', lineColor).attr('stroke-width', this.lineWidthForSeries(lineIndex)).attr('stroke-dasharray', this.options.lineStyle); 
 
    }; 
 
}).call(this); 
 

 
Morris.Area({ 
 
    element: 'chart', 
 
    data: [ 
 
    { y: 'LUN', a: 1, b: 2 }, 
 
    { y: 'MAR', a: 2, b: 3 }, 
 
    { y: 'MER', a: 4, b: 2 }, 
 
    { y: 'JEU', a: 2, b: 1 }, 
 
    { y: 'VEN', a: 2, b: 2 }, 
 
    { y: 'SAM', a: 4, b: 3 }, 
 
    { y: 'DIM', a: 1, b: 2 } 
 
    ], 
 
    xkey: 'y', 
 
    ykeys: ['a', 'b'], 
 
    labels: ['Label 1', 'Label 2'], 
 
    fillOpacity: 0.6, 
 
    hideHover: 'auto', 
 
    behaveLikeLine: true, 
 
    resize: true, 
 
    pointFillColors: ['#ffffff'], 
 
    pointStrokeColors: ['black'], 
 
    lineColors: ['gray', 'blue'], 
 
    lineStyle: ".", 
 
    parseTime: false, 
 
    smooth: false, 
 
    hoverCallback: function (index, options, content, row) { 
 
    var currentDiv = ""; 
 
    var finalContent = $("<div/>"); 
 

 
    $(content).each(function() { 
 
\t \t currentDiv = $(this); 
 
     $(finalContent).append(currentDiv); 
 
    }); 
 
      
 
    var btnEdit = $("<img/>").attr("src", "http://i.stack.imgur.com/Z2AxP.png").addClass("morrisEdit").css({"cursor":"pointer"}).attr("onclick", "editAction();"); 
 
    $(finalContent).append(btnEdit); 
 
    return finalContent;  
 
    } 
 
}); 
 

 
function editAction() { 
 
    alert("Edit Clicked"); 
 
    // Do some actions 
 
}

靜態的解決方案：

(function() { 
 
    var $, MyMorris; 
 

 
    MyMorris = window.MyMorris = {}; 
 
    $ = jQuery; 
 

 
    MyMorris = Object.create(Morris); 
 

 
    MyMorris.Grid.prototype.gridDefaults["lineStyle"] = ""; 
 

 
    MyMorris.Line.prototype.drawLinePath = function (path, lineColor, lineIndex) { 
 
     return this.raphael.path(path).attr('stroke', lineColor).attr('stroke-width', this.lineWidthForSeries(lineIndex)).attr('stroke-dasharray', this.options.lineStyle); 
 
    }; 
 
}).call(this); 
 

 
var data = [ 
 
{ y: 'LUN', a: 1, b: 2 }, 
 
{ y: 'MAR', a: 2, b: 3 }, 
 
{ y: 'MER', a: 0, b: 2 }, 
 
{ y: 'JEU', a: 2, b: 1 }, 
 
{ y: 'VEN', a: 2, b: 2 }, 
 
{ y: 'SAM', a: 0, b: 0 }, 
 
{ y: 'DIM', a: 1, b: 2 } 
 
]; 
 

 
Morris.Area({ 
 
    element: 'chart', 
 
    data: data, 
 
    xkey: 'y', 
 
    ykeys: ['a', 'b'], 
 
    labels: ['Label 1', 'Label 2'], 
 
    fillOpacity: 0.6, 
 
    hideHover: 'auto', 
 
    behaveLikeLine: true, 
 
    resize: true, 
 
    pointFillColors: ['#ffffff'], 
 
    pointStrokeColors: ['black'], 
 
    lineColors: ['gray', 'blue'], 
 
    lineStyle: ".", 
 
    parseTime: false, 
 
    smooth: false, 
 
}); 
 

 
var indexNulls = []; 
 

 
for (var i = 0; i < data.length; i++) { 
 
    if (data[i].a == 0 || data[i].b == 0) { 
 
     indexNulls.push(i); 
 
    } 
 
} 
 

 
for (var i = 0; i < indexNulls.length; i++) { 
 
    var circleElement = $("#chart").find("circle")[indexNulls[i]]; 
 
    var divPosition = $(circleElement).attr("cx") - 20; 
 
    $divEdit = $("<div/>").css({ "display": "inline-block", "position": "absolute", "left": divPosition + "px" }); 
 
    $btnEdit = $("<img/>").attr("src", "http://i.stack.imgur.com/Z2AxP.png").addClass("morrisEdit").css({ "cursor": "pointer" }).attr("onclick", "editAction();"); 
 
    $divEdit.append($btnEdit); 
 
    $("#edits").append($divEdit); 
 
} 
 

 
function editAction() { 
 
    alert("Edit Clicked"); 
 
    // Do some actions 
 
}
