Following is an example of a customized calendar chart. A calendar chart is used to visualize data over a period of time. We’ve already seen the configuration used to draw this chart in the Google Charts Configuration Syntax chapter. So, let’s see the complete example.
Configurations
We’ve used calendar configuration to customize the calendar.
// Set chart options
var options = {
calendar: {
yearLabel: {
fontName: 'Times-Roman',
fontSize: 32,
color: '#1A8763',
bold: true,
italic: true
},
monthOutlineColor: {
stroke: '#981b48',
strokeOpacity: 0.8,
strokeWidth: 2
},
unusedMonthOutlineColor: {
stroke: '#bc5679',
strokeOpacity: 0.8,
strokeWidth: 1
}
}
};
