GetValueSize() → {number}

The GetValueSize() method gets the size to show a column or a bar within the chart. The valueSize has no effect for xy or circular-compatible chart types. The valueSize has effect for area-compatible chart types as follows:
  • "area" {string}, an area chart or area graph displays graphically quantitative data. It is based on the line chart. The area between axis and line are commonly emphasized with colors, textures and hatchings. Commonly one compares two or more quantities with an area chart. (data requires array of numbers, supports vertical field, scrollable)
  • "line" {string}, a line chart or line graph, also known as curve chart is a type of chart which displays information as a series of data points called 'markers' connected by straight line segments. It is a basic type of chart common in many fields. It is similar to a scatter plot except that the measurement points are ordered (typically by their x-axis value) and joined with straight line segments. 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. In these cases they are known as run charts. (data requires array of numbers, supports vertical field, scrollable)
  • "column" {string}, a column chart or column graph is a chart or graph that presents categorical data with rectangular columns with heights proportional to the values that they represent. A horizontal column chart is called a bar chart. (data requires array of numbers, supports vertical field, scrollable)
  • "waterfall" {string}, 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)
  • "rangeArea" {string}, a range chart displays sets of data points, each of which is defined by multiple values for the same category, and emphasizes the distance between the two values. The category labels are displayed on the category axis. The plain Range chart fills in the area between the top and the bottom value for each data point. (data requires array of array of two-numbers, such as [[from, to]], supports vertical field, scrollable)
  • "rangeColumn" {string}, a range column chart displays information as a range of data by plotting two Y-values (low and high) per data point. The vertical axis shows the values, and the horizontal axis shows the categories they belong to; in multiple-series range column charts, values are grouped by categories. (data requires array of array of two-numbers, such as [[from, to]], supports vertical field, scrollable)
  • "candleStick" {string}, 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" {string}, 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)

CSSColor or CSS legal color values can be specified by the following methods:

  • Hexadecimal colors, is specified with: #RRGGBB, where the RR (red), GG (green) and BB (blue) hexadecimal integers specify the components of the color. All values must be between 00 and FF. For example, #0000ff value is rendered as blue, because the blue component is set to its highest value (ff) and the others are set to 00.
  • Hexadecimal colors with transparency, is specified with: #RRGGBBAA, where AA (alpha) value must be between 00 and FF. For example, #0000ff80 defines a semi-transparent blue.
  • RGB colors, is specified with the RGB(red, green, blue) function. Each parameter (red, green, and blue) defines the intensity of the color and can be an integer between 0 and 255. For example, rgb(0,0,255) defines the blue color.
  • RGBA colors, are an extension of RGB color values with an alpha channel as RGBA(red, green, blue, alpha) function, where the alpha parameter is a number between 0.0 (fully transparent) and 1.0 (fully opaque). For example, rgba(0,0,255,0.5) defines a semi-transparent blue.
  • HSL colors, is specified with the HSL(hue, saturation, lightness) function, where hue is a degree on the color wheel (from 0 to 360) - 0 (or 360) is red, 120 is green, 240 is blue. saturation is a percentage value; 0% means a shade of gray and 100% is the full color. lightness is also a percentage; 0% is black, 100% is white. HSL stands for hue, saturation, and lightness - and represents a cylindrical-coordinate representation of colors. For example, hsl(240, 100%, 50%) defines the blue color.
  • HSLA colors, are an extension of HSL color values with an alpha channel - which specifies the opacity of the object as HSLA(hue, saturation, lightness, alpha) function, where alpha parameter is a number between 0.0 (fully transparent) and 1.0 (fully opaque). For example, hsla(240, 100%, 50%,0.5) defines a semi-transparent blue.
  • Predefined/Cross-browser color names, 140 color names are predefined in the HTML and CSS color specification. For example, blue defines the blue color.
Example
null {null}, the tfi field is ignored
  "bold monospace 16 &lt;fg blue>" {string}, defines Monospace font of 16px height, bold and blue
  {bold: true, fontName: "monospace", fontSize: 16, fgColor: "blue"} {object}, defines Monospace font of 16px height, bold and blue

SetValueAxis

SetValueSize(value)

The SetValueSize() method sets the size to show a column or a bar within the chart. The valueSize has no effect for xy or circular-compatible chart types. The valueSize has effect for area-compatible chart types as follows:
  • "area" {string}, an area chart or area graph displays graphically quantitative data. It is based on the line chart. The area between axis and line are commonly emphasized with colors, textures and hatchings. Commonly one compares two or more quantities with an area chart. (data requires array of numbers, supports vertical field, scrollable)
  • "line" {string}, a line chart or line graph, also known as curve chart is a type of chart which displays information as a series of data points called 'markers' connected by straight line segments. It is a basic type of chart common in many fields. It is similar to a scatter plot except that the measurement points are ordered (typically by their x-axis value) and joined with straight line segments. 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. In these cases they are known as run charts. (data requires array of numbers, supports vertical field, scrollable)
  • "column" {string}, a column chart or column graph is a chart or graph that presents categorical data with rectangular columns with heights proportional to the values that they represent. A horizontal column chart is called a bar chart. (data requires array of numbers, supports vertical field, scrollable)
  • "waterfall" {string}, 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)
  • "rangeArea" {string}, a range chart displays sets of data points, each of which is defined by multiple values for the same category, and emphasizes the distance between the two values. The category labels are displayed on the category axis. The plain Range chart fills in the area between the top and the bottom value for each data point. (data requires array of array of two-numbers, such as [[from, to]], supports vertical field, scrollable)
  • "rangeColumn" {string}, a range column chart displays information as a range of data by plotting two Y-values (low and high) per data point. The vertical axis shows the values, and the horizontal axis shows the categories they belong to; in multiple-series range column charts, values are grouped by categories. (data requires array of array of two-numbers, such as [[from, to]], supports vertical field, scrollable)
  • "candleStick" {string}, 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" {string}, 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)
Parameters:
Name Type Description
value number Specifies size to show a column or a bar within the chart. The size indicates the width for horizontally-oriented charts or height for the vertically-oriented chart types
Example
4 {number}, sets the column/bar's width to 4-pixels
