Grafico delle serie temporali

Quantitative data collected at different time points are  called time-series data.  

For example, consider the increase in water temperature when heated. Such data sets with a time factor can be visualized using the time-series graph.

Begin by measuring the temperature of the water at regular intervals and noting it in a table. Next, plot a graph with time represented on the X-axis and temperature on the Y-axis. 

Then, mark the measured temperature at each time interval and draw a continuous line connecting all these data points. Using this graph, one can conclude that it took 15 minutes to bring water to 100 degrees Celsius. 

Other examples of time-series graphs include the stock price of a company, pulse rate, and weather reports.
