[英]Stacked Column Annotations Google Charts
While creating a stacked column chart using google charts, the annotations are getting overlapped due to large amount data.使用谷歌图表创建堆积柱形图时,由于数据量大,注释会重叠。 Is there anyway to get it adjusted.
有没有办法调整一下。 Like displaying only for every 3rd column.
就像只为每第三列显示。 I know this concept works fine with highcharts but I was looking for free charts.
我知道这个概念适用于 highcharts,但我一直在寻找免费图表。
Annotation function call is :--注释函数调用是:--
function drawVisualization() {
var json;
$.getJSON('end.json', function (json) {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Time');
data.addColumn('number', 'Run 3');
data.addColumn({ type: 'number', role: 'annotation' });
data.addColumn('number', 'Run 2');
data.addColumn({ type: 'number', role: 'annotation' });
data.addColumn('number', 'Run 1');
data.addColumn({ type: 'number', role: 'annotation' });
for (var i = 0; i< json[0].data.length; i++){
data.addRow([json[0].data[i], json[3].data[i],json[3].data[i],json[2].data[i],json[2].data[i],json[1].data[i], json[1].data[i]]);
}
var options = {
title: "End to End Processing",
tooltip: {isHtml: true},
legend:{position:"right"},
isStacked:true,
height:window.innerHeight,
width: window.innerWidth,
bar: {groupWidth: '3'},
focusTarget: 'category',
vAxis: {
viewWindowMode:'explicit',
viewWindow: {
max:60,
min:0
},
gridlines :{count:6},
title:'Time in mins',
format: 'short'
},
hAxis: {
format: 'd/m/y',
textStyle : {
fontSize: 9
},
slantedText: true,
slantedTextAngle: 270
},
annotations: {
textStyle: {
color: 'black',
fontSize: 11,
fontStyle: 'bold'
},
stemLength: 20,
displayAnnotationsFilter: true,
legendPosition: 'newRow'
},
series: {
0:{color:'lightgreen'},
1:{color:'black'},
2:{color:'#1E90FF',},
3:{ type: 'line', lineWidth: 0, visibleInLegend:false, pointSize: 0}
}
}
var chart = new google.visualization.ColumnChart(document.getElementById('chart_div'));
chart.draw(data, options);
});
$(window).resize(function(){
drawVisualization();
});
}
Regards.问候。
there isn't a standard option, but you can use null
for blank annotations没有标准选项,但您可以对空白注释使用
null
when loading, try the following to show annotations for every third row...加载时,请尝试以下操作以显示每第三行的注释...
for (var i = 0; i< json[0].data.length; i++){
var annotation1 = null;
var annotation2 = null;
var annotation3 = null;
if ((i % 3) === 0) {
var annotation3 = json[3].data[i];
var annotation2 = json[2].data[i];
var annotation1 = json[1].data[i];
}
data.addRow([
json[0].data[i],
json[3].data[i],
annotation3,
json[2].data[i],
annotation2,
json[1].data[i],
annotation1
]);
}
