我使用组合谷歌图表在图表上显示我的数据和目标,如下所示:
我想在图表的整个宽度上显示目标线,如下所示:
这是我尝试但没有运气的事情:

legend: { position: 'bottom' },
vAxis: {title: ""},
hAxis: {title: ""},
seriesType: "bars",
series: {2: {type: "line", visibleInLegend: false, color: "red"}, 3:{type: "line", visibleInLegend: false, color: "red"}}

}
google.setOnLoadCallback(drawVisualization);

<body style="font-family: Arial;border: 0 none;">
<div id="visualization" style="width: 600px; height: 400px;"></div>

我怎样才能做到这一点?

要将线条扩展到图表边缘,您必须使用连续类型轴,并在现有数据之前和之后将数据集扩展一行。您可以使用DataView将字符串标签转换为格式化数字,然后使用hAxis.ticks
选项设置轴标签:
function drawVisualization() {
// Create and populate the data table.
var data = google.visualization.arrayToDataTable([
['Month', 'RUH %', 'SJA %', 'Goal 30', 'Goal 60'],
['', null, null, 30, 60],
['GKP', 16, 93, 30, 60],
['HKP', 13, 11, 30, 60],
['SKP', 15, 11, 30, 60],
['AEV', 19, 80, 30, 60],
['AE', 63, 69, 30, 60],
['', null, null, 30, 60]
]);
var ticks = [];
// ignore the first and last rows
for (var i = 1; i < data.getNumberOfRows() - 1; i++) {
ticks.push({v: i, f: data.getValue(i, 0)});
}
var view = new google.visualization.DataView(data);
view.setColumns([{
type: 'number',
label: data.getColumnLabel(0),
calc: function (dt, row) {
return {v: row, f: dt.getValue(row, 0)};
}
}, 1, 2, 3, 4]);
var range = view.getColumnRange(0);
var offset = 0.5; // change this value to adjust the padding to the left and right of the columns in the chart
// Create and draw the visualization.
var ac = new google.visualization.ComboChart(document.getElementById('visualization'));
ac.draw(view, {
title : 'RUH og SJA måloppnåelse',
width: 600,
height: 400,
chartArea: {
width: '90%',
height: '80%'
},
colors: ["blue", "green"],
legend: {
position: 'bottom'
},
vAxis: {
title: ""
},
hAxis: {
title: "",
ticks: ticks,
viewWindow: {
min: range.min + offset,
max: range.max - offset
},
gridlines: {
// hide vertical gridlines to match discrete chart display
color: 'transparent'
}
},
seriesType: "bars",
series: {
2: {
type: "line",
visibleInLegend: false,
color: "red"
},
3:{
type: "line",
visibleInLegend: false,
color: "red"
}
}
});
}
