Hi,
I have a question about how to customize a line chart with two series when
the focusTarget: "category" option is set. Is there a way to customize the
display of the tooltip like there is when focusTarget is set to datum?
Using a column set to the tooltip role doesn't seem to work since that just
returns the default tooltip with raw HTML, instead of the customized,
rendered HTML tooltip.
For example, taking an example from the Data Roles docs,
google.load('visualization', '1.1', {'packages':['corechart']});
google.setOnLoadCallback(drawChart_C6);
function drawChart_C6() {
var data = new google.visualization.DataTable();
data.addColumn({type: 'string', role: 'domain'}, '2009 Quarter');
data.addColumn('number', '2009 Sales');
data.addColumn('number', '2009 Expenses');
data.addColumn({type: 'string', role: 'domain'}, '2008 Quarter');
data.addColumn('number', '2008 Sales');
data.addColumn('number', '2008 Expenses');
// tooltip column
data.addColumn({ type: "string", role: "tooltip", p: { html: true }});
data.addRows([
['Q1 \'09', 1000, 400, 'Q1 \'08', 800, 300, "<h1>tooltip</h1>"],
['Q2 \'09', 1170, 460, 'Q2 \'08', 750, 400, "<h1>tooltip</h1>"],
['Q3 \'09', 660, 1120, 'Q3 \'08', 700, 540, "<h1>tooltip</h1>"],
['Q4 \'09', 1030, 540, 'Q4 \'08', 820, 620, "<h1>tooltip</h1>"]
]);
var chart = new google.visualization.LineChart(document.getElementById(
'visualization'));
chart.draw(data, {width: 400, height: 240, legend:'right', focusTarget:
'category', tooltip: {isHtml: true}});
}
Is what I'm asking possible using a category focusTarget? Thanks in advance.
