 #### Supported Charts

Charts are a great tool for web calculators because they display information visually. We support a number of different chart types like line, pie, doughnut, bar, column, stacked, XY, bubble, waterfall, and stock charts. Herewith are descriptions of the charts currently supported by our web calculators.

##### Line Chart

A line chart is a type of chart which displays information as a series of data points connected by straight line segments. It is a basic type of chart common in many fields. A line chart is often used to visualize a trend in data over intervals of time – a time series – thus the line is often drawn chronologically.

##### Pie Chart

A pie chart is a circular chart used to display proportions of a whole. In a pie chart, the arc length of each sector and consequently its central angle and area, is proportional to the quantity it represents. In the corporate world, market share is the obvious example of data that can be represented with pie charts.

##### Doughnut Chart

A doughnut chart (also donut) is functionally identical to a pie chart, with the exception of a blank center. Doughnut chart provides a better data intensity ratio to standard pie chart since the blank center can be used to display additional data.

##### Column Chart

A column chart is a chart with rectangular bars of lengths usually proportional to the magnitudes or frequencies of what they represent. The bars are vertically oriented. Column charts are useful for showing data changes over a period of time or for illustrating comparisons among items.

##### Bar Chart

A bar chart is a chart with rectangular bars of lengths usually proportional to the magnitudes or frequencies of what they represent. The bars are horizontally oriented. Column charts are useful for showing data changes over a period of time or for illustrating comparisons among items.

##### Stacked Chart

A stacked chart is a chart that is used to compare the parts to the whole. The bars in a stacked chart are divided into categories. Each bar represents a total. The bars can be horizontally or vertically oriented.

##### XY Chart

A XY Chart is a type of chart which displays values for two variables for a set of data. The data is displayed as a collection of points, each having the value of one variable determining the position on the horizontal axis and the value of the other variable determining the position on the vertical axis. This kind of chart is also called a scatter chart.

##### Bubble Chart

A bubble chart is a type of chart that displays three dimensions of data by position and size of the bullet. Bubble chart can be considered a variation of the XY Chart, in which the data points are replaced with bubbles. Bubble charts can facilitate the understanding of social, economical, medical, and other scientific relationships.

##### Waterfall Chart

A waterfall chart is a form of data visualization that helps in understanding the cumulative effect of sequentially introduced positive or negative values. A waterfall chart is used to represent a set of figures when they all impact the same derived number. A waterfall chart helps to link the individual values to a whole. A profit and loss statement is a good example where the magnitude of each figure has an impact on a derived number.

##### Stock Chart

A stock chart is a type of chart which primarily describes price movements of a security, derivative, or currency for a designated span of time. It is a combination of a line-chart and a bar-chart, in that each bar represents the range of price movement over a given time interval. It is most often used in technical analysis of equity and currency price patterns. This kind of chart is also called a candlestick chart.
