	Create Pie Chart
		In the Pie chart, length of sheet of each sector (and, hence, its central corner and area), it is proportional to number which represents it.
		The chart with one or several sectors which are separated from other part of a disk, name the Pie chart.
		The Pie chart (or the Pie chart) is the allocated count who is used in the statistician.

	Good Charts
		Pie charts are used to represent the distribution of the categorical components of a single variable. Note that as a general rule, multivariate comparisons provide for more meaningful analysis than do single variable distributions and for this and other reasons pie charts should be rarely used, if at all.
		Pie charts usually contain more ink than is necessary to display the data and the slices provide for a poor representation of the magnitude of the data points.
		One common bar charting mistake is including the legend on the right-hand side of the plot area (shown in figure 12), placing the legend inside the plot area, as in figure 9, or horizontally under the table title (as in figure 11) maximizes the size of the area given over to displaying the data.

	Using Data and Statistics
		A pie chart is a circle graph divided into pieces, each displaying the size of some related piece of information.
		Pie charts are used to display the sizes of parts that make up some whole.
		This is the same value as in the pie chart in the previous example.

	Pie Chart and Donut Charts for ASP.NET by .net CHARTING
		Pie Chart and Donut Charts for ASP.NET by.net CHARTING
		Donut charts are identical to pie charts except for the fact that a hole is cut out of the center of the circular surface, creating a donut shape.
		Chart series can each render as a slice for a single pie or multiple series can be drawn with their own pie for each series.

	Learning Resources: Statistics: Power from data! Pie charts
		A pie chart is a way of summarizing a set of categorical data or displaying the different values of a given variable (e.g., percentage distribution).
		Pie charts are also one of the most commonly used charts because they are simple to use.
		Second, pie charts are not useful when the values of each component are similar because it is difficult to see the differences between slice sizes.

	Pie Charts in Microsoft Excel
		Pie charts are good when you are showing the relative proportion of numbers that add up to a total.
		Pie charts are not good for quantitative displays, because it's hard to judge the relative angle of the wedges at different orientations.
		Pie charts are a poor choice for comparing two sets of proportions, i.e., multiple series of data.

	CodeProject: 3D Pie Chart. Free source code and programming help
		When drawing a 3-D pie slice (with some finite height), it is necessary to draw the slice cut sides as well as the outer periphery of the cylinder from which the slice is cut out.
		The pie shape that is crossing the 270 degrees boundary must be drawn first because it may be (partially) covered by another pie slice.
		A simple pie chart printing sample has been included into the demo project (please note that the quality of the printout depends on the capabilities of the printer and is usually far behind the screen display quality).

	Pie and Donut Chart
		The data points in a pie chart are displayed as a percentage of the whole pie.
		Doughnut chart are functionally identical to pie charts, it also has single-series and multi-series versions, the only difference is that it has a hole in the middle.
		Pie and doughnut charts can not be combined with any other charts, so they have their own plot_type="Pie" and plot_type="Doughnut", so if one of this plot types is set - all series in a chart will be plotted as pies or doughnuts.

	Pie of Pie Charts and other Pie Chart Tricks
		The Bar of Pie chart type is similar to the pie of pie chart type, except the secondary chart is a small stacked bar rather than a small pie.
		Make the chart area (the bounding area of the chart, shown at right in green) square or close to square, then enlarge the plot area (the square that encloses the pie, shown in yellow) to fill as much of the chart area as possible.
		Another way to separate the many wedges of a pie chart into groupings of wedges is to drag the wedges away from the center of the pie.

	Pie Chart Tutorial
		Pie charts are only suitable for one row of numbers, each number represented by a pie piece on the chart.
		Your pie chart is using uses the numbers from the first row.
		Since pie charts cannot represent negative numbers a bar or a line graph chart would be the right choice when your data includes negative values.

	Many Eyes: Pie Chart
		The percentages are encoded are "slices" of a pie, with the area corresponding to the percentage.
		The pie chart needs one column of text, for labeling slices, and at least one numeric column for slice values.
		It's also unclear whether exact communication of numeric values is the only evaluation criterion; at least one study indicates that use of a pie chart for analyzing a problem as opposed to a bar chart changes the way people think about the problem.

	Pie Chart created from drawing API and text file content
		The pie chart above was coded entirely in script (nothing on stage, nothing in the library), using the Flash MX drawing API, event handlers and a data file (as described at the bottom of the text file page), read in with an instance of LoadVars.
		Data for the pie chart comes from piechartsampledata.txt, in the same format and read in the same way as described on the Text Files page (second example).
		The wedge's angle property (size of each wedge of the pie in degrees) is calculated by dividing the count for the corresponding item by the sum of all counts and multiplying that fraction by 360 (total number of degrees in the pie).

	Jan's Excel Format & Arrange: Format Pie Chart
		Pie charts are most useful for showing how the parts relate to the whole.
		In the sample chart below, the sizes of the wedges give you a quick feel for the relative sizes - which pieces are biggest, which are smallest, which are about the same size, which parts make up the bulk of the whole.

	Using Pie Chart
		The Pie Chart is different from the other charts in terms of the input data that it receives.
		Add the chart to the frame, set the size of the frame and set it to be visible.
		Thus the Pie chart can be plotted and the methods / properties in it can be used for much more customization.

	Pie chart spacing problem for small values in CFCHART (Tom Mollerus' Weblog)
		Built-in charting capability is definitely one of the great conveniences of using ColdFusion over other languages (although I'd argue that Google's Chart API, which lets any developer call custom charts through a REST API, is eroding that advantage; more on that later).
		Of the three numbers we're sending to the chart, one is quite a bit larger than the other two and thus takes up most of the pie's area.
		When the pie wedges are that small, the labels have a tendency to collide, or overlay one another.

	Junk Charts: Pie chart
		This is one of those polls that allow respondents to pick any number of factors and clearly, the pie chart creator used the 1,151 responses as the baseline, as opposed to 910 people who voted.
		Combining the data given in the bar charts and pie charts, one discovered that 469 out of 910 respondents could not decide which photo was taken before the other; besides, these respondents on average expressed 0.9 opinions on the decision factors whereas the respondents who made a decision expressed 1.6 opinions.
		From this chart, one sees that the number and position of the cannon balls were crucial to at least 50% of those who came to a conclusion.
