Hi All,
I'm trying to see if this is possible.
I have an existing chart which combines bars and two areas as below:
function drawVisualization() {
// Create and populate the data table.
var data = google.visualization.arrayToDataTable([
['Day', 'Actual', 'Base','Uplift'],
['2013-05-01',140,100,25],
['2013-05-02',75,80,22],
['2013-05-03',130,105,10],
['2013-05-04',110,75,18],
['2013-05-05',205,140,25]
]);
// Create and draw the visualization.
var ac = new google.visualization.ComboChart(document.getElementById(
'visualization'));
ac.draw(data, {
width: 600,
height: 400,
colors:['#109618','rgb(184,204,228)','rgb(0,112,192)'],
vAxis: {title: "Cups", minValue: 0},
hAxis: {slantedTextAngle: 45},
seriesType: "bars",
isStacked:true,
series: {1: {type: "area", areaOpacity:5}, 2: {type: "area", areaOpacity
:5}}
});
}
I need to be able to highlight / mark a date range i.e. 2013-05-02 through
2013-05-04. I need this to have a fill and be slightly transparent, it
should be behind all the other layers and take up 100% of the height of the
chart.
I tried to use area again and create another series which was effectively
the same value as 100% height of the chart but it wasn't working because
this chart is configured to use stacking.
Any ideas?
Tom
