【问题描述】：
我正在研究 angularjs 谷歌图表。我正在使用 angularjs google 柱形图以列的形式显示数据，问题是当我有更多数据来显示条形宽度正在减小时。如果要显示更多数据，如示例here 所示，我想显示带有水平滚动条的图表。 我尝试实现相同但无法显示滚动条，任何建议都会有所帮助。
我的示例演示here
js代码：
angular.module('myApp', ['googlechart'])
.controller('myController', function($scope) {
var chart1 = {};
chart1.type = "ColumnChart";
chart1.displayed = false;
chart1.data = {
"cols": [{
id: "month",
label: "Month",
type: "string"
}, {
id: "laptop-id",
label: "Laptop",
type: "number"
}, {
id: "desktop-id",
label: "Desktop",
type: "number"
}, {
id: "server-id",
label: "Server",
type: "number"
}, {
id: "cost-id",
label: "Shipping",
type: "number"
}],
"rows": [{
c: [{
v: "January"
}, {
v: 19,
f: "42 items"
}, {
v: 12,
f: "Ony 12 items"
}, {
v: 7,
f: "7 servers"
}, {
v: 4
}]
}, {
c: [{
v: "February"
}, {
v: 13
}, {
v: 1,
f: "1 unit (Out of stock this month)"
}, {
v: 12
}, {
v: 2
}]
}, {
c: [{
v: "March"
}, {
v: 24
}, {
v: 5
}, {
v: 11
}, {
v: 6
}
]
}, {
c: [{
v: "April"
}, {
v: 24
}, {
v: 5
}, {
v: 11
}, {
v: 6
}
]
}, {
c: [{
v: "May"
}, {
v: 18
}, {
v:11
}, {
v: 7
}, {
v:2
}
]
}, {
c: [{
v: "June"
}, {
v: 21
}, {
v: 5
}, {
v: 8
}, {
v: 6
}
]
}, {
c: [{
v: "July"
}, {
v: 24
}, {
v: 5
}, {
v: 9
}, {
v: 9
}
]
}, {
c: [{
v: "August"
}, {
v: 14
}, {
v: 1
}, {
v: 11
}, {
v: 5
}
]
}, {
c: [{
v: "September"
}, {
v: 4
}, {
v: 2
}, {
v: 51
}, {
v: 6
}
]
}, {
c: [{
v: "October"
}, {
v: 34
}, {
v: 4
}, {
v: 0
}, {
v: 1
}
]
}]
};
chart1.options = {
"title": "Sales per month",
"colors": ['#0000FF', '#009900', '#CC0000', '#DD9900'],
"defaultColors": ['#0000FF', '#009900', '#CC0000', '#DD9900'],
"isStacked": "true",
"fill": 20,
"displayExactValues": true,
"vAxis": {
"title": "Sales unit",
"gridlines": {
"count": 10
}
},
"hAxis": {
"title": "Date"
}
};
chart1.view = {
columns: [0, 1, 2, 3, 4]
};
$scope.myChart = chart1;
$scope.seriesSelected = function(selectedItem) {
console.log(selectedItem);
var col = selectedItem.column;
//If there's no row value, user clicked the legend.
if (selectedItem.row === null) {
//If true, the chart series is currently displayed normally. Hide it.
console.log($scope.myChart.view.columns[col]);
if ($scope.myChart.view.columns[col] == col) {
//Replace the integer value with this object initializer.
$scope.myChart.view.columns[col] = {
//Take the label value and type from the existing column.
label: $scope.myChart.data.cols[col].label,
type: $scope.myChart.data.cols[col].type,
//makes the new column a calculated column based on a function that returns null,
//effectively hiding the series.
calc: function() {
return null;
}
};
//Change the series color to grey to indicate that it is hidden.
//Uses color[col-1] instead of colors[col] because the domain column (in my case the date values)
//does not need a color value.
$scope.myChart.options.colors[col - 1] = '#CCCCCC';
}
//series is currently hidden, bring it back.
else {
console.log("Ran this.");
//Simply reassigning the integer column index value removes the calculated column.
$scope.myChart.view.columns[col] = col;
console.log($scope.myChart.view.columns[col]);
//I had the original colors already backed up in another array. If you want to do this in a more
//dynamic way (say if the user could change colors for example), then you'd need to have them backed
//up when you switch to grey.
$scope.myChart.options.colors[col - 1] = $scope.myChart.options.defaultColors[col - 1];
}
}
};
});
我尝试在chart1.options 上面的 js 代码中添加以下代码，但没有成功：
width: chart1.data.getNumberOfRows() * 130,
bar: {groupWidth: 90},
【问题讨论】：
-
你不能通过设置宽度来使用 css 来做同样的事情吗？
-
我使用过，但是当条数更多时，它会减小条形宽度。我想保持与现在显示的条形大小相同，所以我认为我们需要以不同的方式处理它。跨度>
