"candlestick", a candlestick chart (also called Japanese candlestick chart or K-line) is a style of financial chart used to describe price movements of a security, derivative, or currency. While similar in appearance to a bar chart, each candleStick represents four important pieces of information for that day: open and close in the thick body, and high and low in the "candle wick". Being densely packed with information, it tends to represent trading patterns over short periods of time, often a few days or a few trading sessions. (data requires array of array of four-numbers, such as [[open, high, low and close]], supports vertical field, scrollable)

"ohlc", an open-high-low-close chart (also OHLC) is a type of chart typically used to illustrate movements in the price of a financial instrument over time. Each vertical line on the chart shows the price range (the highest and lowest prices) over one unit of time, e.g., one day or one hour. Tick marks project from each side of the line indicating the opening price (e.g., for a daily bar chart this would be the starting price for that day) on the left, and the closing price for that time period on the right. The bars may be shown in different hues depending on whether prices rose or fell in that period. (data requires array of array of four-numbers, such as [[open, high, low and close]], supports vertical field, scrollable)

"bubble", a bubble chart or bubble plot is a type of chart that displays three dimensions of data (a bubble chart is an extension of the scatter plot used to look at relationships between three numeric variables.). Each entity with its triplet (v1, v2, v3) of associated data is plotted as a disk that expresses two of the vi values through the disk's xy location and the third through its size. Bubble charts can facilitate the understanding of social, economical, medical, and other scientific relationships.
