# How to show Percentage in gauge chart of Angular google chart package?

I am developing an application where I am going to show a gauge chart. I am using the angular-google-chart package.

I implement a basic gauge type chart. Instead of showing the flat number like 0, 100 and 78, I want to show 0%, 100% and 78% here. To do this, I am using the below coding snippet.

@ViewChild('googlechart')
public gaugeChart = {
type: 'Gauge',
data: [
['Water', 35]
],
options: {
width: 500,
height: 500,
greenFrom: 50,
greenTo: 100,
redFrom: 0,
redTo: 20,
yellowFrom: 20,
yellowTo: 50,
minorTicks: 5
}
};
