I have a Google Combination Chart where I am using two y axes.
At present, the baselines for each axis are at a different level.
I wish to ensure that the baselines for each axis are at the same level.
The code I am currently using to display my graph is shown below:
<html>
<head>
<script type="text/javascript" src="https://www.google.com/jsapi";
></script>
<script>
google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('number', 'Sales');
data.addColumn('number', 'Total PnL');
data.addColumn('number', 'Total Margin');
data.addRows([ [6.5,150.6,0.6604],
[7.0,-275,-1],
[7.5,-128.45000,-0.30368],
[8.0,345.5,0.63904761],
[8.5,-316.56000,-0.07868],
[9.0,-118.26000,-0.09587],
[9.5,-899.0699,-0.236790],
[10.0,-242.6800,-0.40805],
[10.5,28.1700,0.00786] ]);
var options = {
title: 'Graph 1',
tooltip: {textStyle: {fontSize:14}},
titleTextStyle:{fontSize:12},
hAxis: {title: 'time', titleTextStyle: {color: 'red',fontSize:15},
textStyle: {fontSize:11,fontStyle:'bold'}},
legend: {maxLines:5,textStyle: {fontSize: 11.5}},
seriesType: "bars",
series: {
0: {type: "bar",targetAxisIndex:0,color:'#000000'},
1: {type: "line",targetAxisIndex:1,color:'#333333'},
},
vAxes:{
0:{title:'PnL',titleTextStyle: {fontSize:14},textStyle:{color: 'blue',
fontSize:15},format:'£###,###,###'},
1:{title:'Margin',titleTextStyle: {fontSize:14},textStyle:{color: 'red',
fontSize:15},format:'#.###%'}
}
};
var chart = new google.visualization.ComboChart(document.getElementById(
'graphdiv'));
chart.draw(data, options);
}
</script>
</head>
<body>
<div id='graphdiv' style='width: 900px; height: 500px;'></div>
</body>
</html>
This produces the following graph:

I am aware that making use of the minValue and maxValue properties of each
of the vAxes could be one way of dealing with this situation. But I am not
sure how exactly I might do so.
Also, are there any future plans to make this a simple matter of adding
baseline-equal:true
to the vAxes options?
I apologise if this is the incorrect forum in which to ask about this issue.
