Final answer:
To convert a snapshot graph to a history graph, identify the dataset, collect the same data at regular intervals, and plot them on a graph with time on the x-axis to visualize changes over time.
Step-by-step explanation:
To convert a snapshot graph into a history graph, you must first understand the differences between the two. A snapshot graph represents data at a particular point in time, whereas a history graph shows how data changes over a period of time. To convert from a snapshot to a history graph, you need to collect data points for the same variables at successive time intervals.
First, identify the relevant data that will be plotted on the history graph. Then, record this data at regular time intervals. Once you have a series of data points, you can plot them on a graph with the x-axis typically representing time and the y-axis representing the variable you are measuring. Connect the points to visualize the data over time.
For example, if the snapshot graph shows the number of store customers at 3 p.m. on different days, you would record customer counts at 3 p.m. over several days or weeks to create a history graph. Each point on the history graph would represent the number of customers at 3 p.m. on each respective day.
