By default, the SeriesColorsDecrease property is "red". The SeriesColorsDecrease property defines the default colors for the chart's series (when the value goes down). The SeriesColors property specifies the color of the series, while the serie's Color property is not specified. The Color property specifies the color for an individual serie.

Currently, the SeriesColorsDecrease property is valid for the following Type of series:

• "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)
• "waterfall", a waterfall chart is a form of data visualization that helps in understanding the cumulative effect of sequentially introduced positive or negative values. These intermediate values can either be time based or category based. The waterfall chart is also known as a flying bricks chart or Mario chart due to the apparent suspension of columns (bricks) in mid-air. Often in finance, it will be referred to as a bridge. (data requires array of numbers, supports vertical field, scrollable)

For instance:

• "", indicates that the SeriesColorsDecrease property has no effect (all values/items use the SeriesColors/Color property to colorize the serie)
• "black", indicates that all series/items shows in black
