Does a line graph show the relationship between three variables?
a simple 2d xy line graph has only the possibility for 2 different variables (x and y). for a 3 variable graph you would have to go into a 3d xyz graph with each variable as x, y and z. it is possible to fit a line to this but for an easier analysis it is better to analyse the variables in pairs.
What is the difference of a histogram and a table?
A histogram is a graph that for a given set of data show you how many times a certain range of values appears and how it compares to the frequency of ranges of values. A table on the other hand relates two unique sets of numbers, and shows how a value in one set corresponds to values in the other.
What is the difference between a line graph and a scatter diagram?
The terminology "scatter diagram" is used in Microsoft Excel and it causes some confusion. The difference is in the x-axis. If my x data is 1900, 1901 2000 and my y data is 100, 300, 3000, then a line plot (in Excel) would show on the x-axis three regularly spaced marks corresponding to 1900, 1901 and 2000. However, on a scatter diagram, intervals are always numerically equal, so 1900 and 1901 are very close together. Scatter diagram, as Microsoft defines them, can show line only, lines and points or just points. It is the preferred plot for data in technical/ scientific work. Where the data is sparse and/or alternative interpretation possible, I would suggest showing both points and lines. Line graphs (again, as Microsoft defines it) can distort relationships. See related link below for some good examples.
Why would you use a bar graph?
When wanting to compare information. It makes it easy to see the differences in the heights of 2 or more bars side by side.
What is the name of a curved ine graph?

How are line graphs used in real life?
People use line graphs in businesses, and to compare data. Line graphs are mostly used when people are entrepreneurs. They figure out profit this way. Line graphs are also used when a product is made. They decide if they should continue to make this product, by how well the product sells. Line graphs show the change.
What is the difference between a glyph and a pictograph?
Techniacally there are a few differences, but the basic idea of both a pictograph and glyph is the same. Both are images used to represent a concept,word or sound
What is the difference between a bar graph and line graph?
A bar graph consists of columns of varying height to show data - looking like 'steps' across the page. A line graph uses a continuous line which changes direction with each piece of data.
What is the purpose of the key in a bar graph?
The graph key is to make sure everyone understands what things mean, like a map key
Bar graphs are used to graph frequencies or amounts of data in discrete groups.
Bar graphs are used to display data in a similar way to line graphs. However, rather than using a point on a plane to define a value, a bar graph uses a horizontal or vertical rectangular bar that levels off at the appropriate level.
Did Florence Nightingale invent the pie chart or polar graph?
Florence Nightingale is usually credited with inventing the polar area diagram, there are earlier uses. Léon Lalanne used a polar diagram to show the frequency of wind directions around compass points in 1843. André-Michel Guerry is an earlier inventor of the "rose diagram" form, in an 1829 paper showing frequency of events foAlthough Florence Nightingale is usually credited with this graphical invention, there are earlier uses. Léon Lalanne used a polar diagram to show the frequency of wind directions around compass points in 1843.

What is a continuous line graph?
a continuous line graph is a graph that is similar to a broken line graph but it always grows higher and higher it never goes down. e.g. age
How do you use Excel to draw pie chart?
Select the range of values that you've entered into the spreadsheet that you want to have represented in the chart. Click on the Chart Wizard option which is near the right end of the standard toolbar. When the Chart Wizard opens you will be given a choice of different types of chart to use. Pick one of the Pie Chart formats and then proceed through the following stages, picking whatever additional options you need. When you finish, you will have your chart.
When is it best to use a bar graphs?
