By looking at the dots reaching the positive end of the graph and referring to the legend(if applicable)
Time.
If you can trace the graph without lifting your pencil then it is continuous.
graph apex xD
you use a graph to see your progress
You can definitely use a table or graph to what your findings. You can use a bar graph for this purpose for example.
Graph factor
You use a circle graph when you need to find percentage and/or degrees.
you use a broken line graph usually for showing continuous data (data with growth over time)
Time.
If you can trace the graph without lifting your pencil then it is continuous.
when you can't find any other peice of graph paper
Find out about factors and factor trees.
To find the area under a graph, you can use calculus by integrating the function that represents the graph. This involves finding the definite integral of the function over the desired interval. The result of the integration will give you the area under the graph.

To show continual change from month to month, it would probably be better to use a line graph.

You can use a position-time graph to find the displacement of an object by determining the change in position between the initial and final points on the graph. The displacement is the area under the curve of the graph, which corresponds to the distance traveled by the object in a particular time interval. Mathematically, displacement can be calculated by integrating the velocity-time graph or finding the slope of the graph at different time points.
