You can change the type of the FlexChart control depending on your requirement. Chart type can be changed by setting the ChartType property of the FlexChart control. In this case, if multiple series are added to the FlexChart, all of them are of the same chart type. To know how to add multiple series and to set a different ChartType of each series, see Mixed Charts. FlexChart supports various chart types including Line and LineSymbol chart, Area chart, Bar and Column chart, Bubble chart, Scatter chart, Candlestick chart, etc.

Line and LineSymbol chart
A Line chart draws each series as connected points of data, similar to area chart except that the area below the connected points is not filled. The series can be drawn independently or stacked. It is the most effective way of denoting changes in value between different groups of data. A LineSymbol chart is similar to line chart except that it represents data points using symbols.
These charts are commonly used to show trends and performance over time.

Area chart
An Area chart draws each series as connected points of data and the area below the connected points is filled with color to denote volume. Each new series is drawn on top of the preceding series. The series can either be drawn independently or stacked.
These charts are commonly used to show trends between associated attributes over time.
Bar and Column chart
A Bar chart or a Column chart represents each series in the form of bars of the same color and width, whose length is determined by its value. Each new series is plotted in the form of bars next to the bars of the preceding series. When the bars are arranged horizontally, the chart is called a bar chart and when the bars are arranged vertically, the chart is called column chart. Bar charts and Column charts can be either grouped or stacked.
These charts are commonly used to visually represent data that is grouped into discrete categories, for example age groups, months, etc.

Bubble chart
A Bubble chart represents three dimensions of data. The X and Y values denote two of the data dimensions. The third dimension is denoted by the size of the bubble.
These charts are used to compare entities based on their relative positions on the axis as well as their size.
Scatter
A Scatter chart represents a series in the form of points plotted using their X and Y axis coordinates. The X and Y axis coordinates are combined into single data points and displayed in uneven intervals or clusters.
These charts are commonly used to determine the variation in data point density with varying x and y coordinates.
Candlestick chart
A Candlestick chart is a financial chart that shows the opening, closing, high and low prices of a given stock. It is a special type of HiLoOpenClose chart that is used to show the relationship between open and close as well as high and low. Candle chart uses price data (high, low, open, and close values) and it includes a thick candle-like body that uses the color and size of the body to reveal additional information about the relationship between the open and close values. For example, long transparent candles show buying pressure and long filled candles show selling pressure.
Elements of a Candlestick chart
The Candlestick chart is made up of the following elements: candle, wick, and tail.
- Candle: The candle or the body (the solid bar between the opening and closing values) represents the change in stock price from opening to closing.
- Wick and Tail: The thin lines, wick and tail, above and below the candle depict the high/low range.
- Hollow Body: A hollow candle or transparent candle indicates a rising stock price (close was higher than open). In a hollow candle, the bottom of the body represents the opening price and the top of the body represents the closing price.
- Filled Body: A filled candle indicates a falling stock price (open was higher than close). In a filled candle the top of the body represents the opening price and the bottom of the body represents the closing price.
In a Candlestick there are five values for each data point in the series.
- x: Determines the date position along the x axis.
- high: Determines the highest price for the day, and plots it as the top of the candle along the y axis.
- low: Determines the lowest price for the day, and plots it as the bottom of the candle along the y axis.
- open: Determines the opening price for the day.
- close: Determines the closing price for the day.
The following image shows a candlestick chart displaying stock prices.
High Low Open Close chart
HiLoOpenClose are financial charts that combine four independent values to supply high, low, open and close data for a point in a series. In addition to showing the high and low value of a stock, the Y2 and Y3 array elements represent the stock's opening and closing price respectively.
Spline and SplineSymbol chart
A Spline chart is a combination of line and area charts. It draws a fitted curve through each data point and its series can be drawn independently or stacked. It is the most effective way of representing data that uses curve fittings to show difference of values. A SplineSymbol chart is similar to Spline chart except that it represents data points using symbols.
These charts are commonly used to show trends and performance over time, such as product life-cycle.

SplineArea chart
SplineArea charts are spline charts that display the area below the spline filled with color. SplineArea chart is similar to Area chart as both the charts show area, except that SplineArea chart uses splines and Area chart uses lines to connect data points.
