Scatter Graph

Scatter charts are used to plot data points on a horizontal and a vertical axis in the attempt to show how much one variable is affected by another. Each row in the data table is represented by a marker whose position depends on its values in the columns set on the X and Y axes.
Note: Choose the file extension as js.

Sample Code

setChartLibrary('google-chart');
setChartTitle('Your Graph Title');
setChartType('scatterGraph');
setAxisName('X-Axis Name','Y-axis Name');
plotChart('time_stamp','your_variable_name');

Output
