@gopa7172,

There are some syntax errors and missing elements in your provided code.

  1. In the setChartLibrary line, it appears that there’s a typo in specifying the Google Chart library. It should be setChartLibrary("google-chart"); with double quotes around “google-chart.”
  2. In the setAxisName line, there seems to be a typo in the second parameter. It should be setAxisName('time stamp', 'frequency'); with single quotes around ‘frequency’ and a semicolon at the end.
setChartLibrary("google-chart");
setChartTitle('Your Graph Title');
setChartType('lineGraph');
setAxisName('time stamp', 'frequency');

plotChart('time_stamp', 'gbfr');
