Stepped Graph
A Step chart is a Line chart that does not use the shortest distance to connect two data points. Instead, it uses vertical and horizontal lines to connect the data points in a series forming a step-like progression. The vertical parts of a Step chart denote changes in the data and their magnitude. The horizontal parts of a Step chart denote the constancy of the data.
Note: Choose the file extension as js.
Sample Code
setChartLibrary('google-chart');
setChartTitle('Your Graph Title');
setChartType('steppedGraph');
setAxisName('time_stamp','light_data','temp');
