A bar graph or line graph usually are the best ways. also tables, charts can work .
Line graph
It can be, but not necessarily. If I had the heights (continuous variable) of a class of students I might use a histogram. Conversely, if I had the number of cars (discrete variable) driving by every minute, I would use a line graph. It all depends on which kind of graph conveys the information to your audience in the best way.
A line graph is shaped like a triangle and a bar graph is exactly like column but bar graph is other way around
A line graph with shadow intensity on the y axis and time on the x axis.
Bar graphs use bars and a line graph is like a scatter graph but with a straight line to see wich way the dots are going.
This question cannot be answered in a sensible way because it is based on a misunderstanding. The dots in a line graph ARE connected. That is what a line graph is. If they are not connected then it is a scatter graph.
The graph of x = 5 is the vertical line which cuts the X-axis at 5. X> 5 is everything (i.e. the plane) to the right of this line.
A line graph is not a good way to represent the data as the number of CDs is a continuous variable, but the artists are a discrete, categoric variable. A line graph should be used when both variables are continuous. A bar chart or bar graph should be used when one variable is continuous and one is discrete.
I would say pie chart but that would be too complicated so an easier but different way would be line graph
by doing a line graph or maybe a bar graph.
No, it is not.
