Hi,
I have this:
dataTable.addColumn('string', 'Date');
dataTable.addColumn('number', 'Forecast');
dataTable.addColumn({id:'date_note', type:'string',
role:'annotation'});
dataTable.addColumn({id:'i2', type:'number',
role:'interval'});
dataTable.addColumn({id:'i2', type:'number',
role:'interval'});
dataTable.addColumn({id:'i2', type:'number',
role:'interval'});
dataTable.addColumn({id:'i2', type:'number',
role:'interval'});
dataTable.addColumn({id:'i2', type:'number',
role:'interval'});
dataTable.addColumn({id:'i2', type:'number',
role:'interval'});
dataTable.addColumn({id:'i2', type:'number',
role:'interval'});
dataTable.addColumn({id:'i2', type:'number',
role:'interval'});
dataTable.addColumn({id:'i2', type:'number',
role:'interval'});
dataTable.addColumn({id:'i2', type:'number',
role:'interval'});
dataTable.addColumn({id:'i2', type:'number',
role:'interval'});
dataTable.addColumn({id:'i2', type:'number',
role:'interval'});
dataTable.addColumn({id:'i2', type:'number',
role:'interval'});
dataTable.addColumn({id:'i2', type:'number',
role:'interval'});
dataTable.addColumn({id:'i2', type:'number',
role:'interval'});
dataTable.addColumn({id:'i2', type:'number',
role:'interval'});
dataTable.addColumn({id:'i2', type:'number',
role:'interval'});
dataTable.addColumn({id:'i2', type:'number',
role:'interval'});
dataTable.addColumn('number', 'Real');
dataTable.addColumn({id:'join', type:'boolean',
role:'certainty'});
and this:
var options = {
title: title,
titleTextStyle: {fontSize: 14, bold: true},
tooltip: {textStyle: {fontSize: 10, bold: true}},
interval: { 'i2': { 'style':'area', 'curveType':'function',
'fillOpacity':0.2, 'color':'gray' }},
legend: { position: 'right' },
colors: ["black", "blue"],
chartArea:{
top: 30,
width: my_width_per,
height: "65%"
},
width: my_width,
height: my_height,
lineWidth: 2,
vAxis: {
title: 'Power (kW)',
textStyle : {
fontSize: 10,
bold: true
},
viewWindow:{
min:minimum
}
},
hAxis: {
title: 'Time horizon',
slantedText: false,
slantedTextAngle: 5,
textStyle : {
fontSize: 10,
bold: true
},
format:'dd-MM-yyyy HH:mm'
},
backgroundColor: '#e4e4e4', //fafafa
pointSize: 3,
};
and the result is:

*How can I include the different gray values in the legend? Lines with role
'interval' are not there...*
