Q:

Google-Line-Chart on hover tool-tip not showing value

I have used Google Line Charts in Angular2 in typescript version, When I draw the line chart, Chart is looking good but when I hover over the line chart to see what is exact value at that point, I can't see any value in tool-tip and I don't understand what can be the problem if the value has been drawn in chart but aren't showing up in tool-tip.I have attached a screenshot for the reference. Sample data array which gets convert into datatable is as follow:
Gdata = [
["TimeStamp", "Temparature"], [Sat May 13 2017 10:45:00 GMT+0530 (India Standard Time), 23.81], [Sat May 13 2017 10:50:00 GMT+0530 (India Standard Time), 23.83], [Sat May 13 2017 10:55:00 GMT+0530 (India Standard Time), 23.90], [Sat May 13 2017 11:00:00 GMT+0530 (India Standard Time), 23.85], [Sat May 13 2017 11:05:00 GMT+0530 (India Standard Time), 23.82]
];

Kindly help. Thanks in advance.

After going through the many options provided by google charts, I found an option called tooltip: { isHtml: true } which worked for me and now tooltip is showing within the chart area only.
