Description (title) of the chart so that you know what the chart is intended to display;
Labels for categories (or independent variable), with scale, if appropriate; and
Values for dependent variable with scale.
A pie chart.
The answer depends on what the comparisons are. A bar graph and a pie chart will probably do well.
Bar charts are good for comparing related items. Answer: for Excel it is best known as a column chart.
a pie Chart :)
Pie chart it is used for percents of a whole, no time included.
A pareto chart combines a bar chart and a line graph that displays the values in descending order as bars and the cumulative totals of each category, left to right, as a line graph. A tally chart shows a cumulative count of items in a category, frequently indicated by a small horizontal line for each four items and a diagonal line for the fifth item. This sequence repeats with groups of five until all items are counted.
A graph typically represents quantitative data using points, lines, or bars, while a chart is a visual representation of data that can include graphs, tables, or diagrams. Graphs are used to show relationships or trends in data, while charts are more general tools for visualizing information.
The chart shows a positive correlation among the three items. As one item increases, the other items also tend to increase. This suggests that there is a relationship where the variables move in the same direction.
a bar graph
A pie chart is round with "slices" to identify data items. A column chart is a series of columns to identify data items. A pie chart allows you to see how all the parts fit into the whole. A column chart allows you to compare all the parts with each other.
Your best chance of getting the correct answer is to ask the student who drew the chart. The type of chart/graph that is best drawn depends upon the data being represented: If the chart is being used to show how data represents a fraction of a whole, a Pie chart would be used. If the chart is of discrete data, eg shoe sizes, a bar chart would be used. If the chart is of continuous data, eg the height of people, a line chart would be used. A pictogram is a version of the bar chart with the bars split up into icons which represent some kind of unit; eg for shoe sales of different styles a shop could use a shoe icon to represent 5 shoes with parts of a shoe icon representing 1-4 shoes sold. In business which of the bar chart and line graph is used depends upon what sort of information is required to be shown and to whom*. For factual information about different items a bar chart is often used (eg how much is sales per month), but if a trend is required a line graph can be used (eg how is sales per month changing). * The "to whom" bit is often the deciding factor - the choice of chart and how it is drawn can be used to great effect to enhance or hide certain aspects of the data.
This describes a double-bar graph.
