A bar chart or bar graph is a chart or graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent. The bars can be plotted vertically or horizontally. A vertical bar chart is sometimes called a column chart and has been identified as the prototype of charts. [1]
The highest and lowest price points are represented by wicks similarly to candlesticks. [1] To calculate the highest and lowest price of a period: Heikin-Ashi High=Max value of (High-0, Open-0, and Close-0) [8] [9] Heikin-Ashi Low=Min value (Low-0, Open-0, and Close-0) [8] (where -0 indicates that values are being taken from the current bar or ...
10 kPa 1.5 psi Pressure increase per meter of a water column [26]: 10 kPa 1.5 psi Decrease in air pressure when going from Earth sea level to 1000 m elevation [citation needed]
An OHLC chart, with a moving average and Bollinger bands superimposed. An open-high-low-close chart (OHLC) is a type of chart typically used in technical analysis 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 ...
Though the lowest pressure may be second to the Night of the big wind low, which saw a value of 27.25 inches of mercury (923 hPa) at Sumburgh Head, Shetland on non-calibrated, non-standard equipment 6–7 January 1839, with the mainland at Cape Wrath reporting an observed pressure of 27.32 inches of mercury (925 hPa).
Bar chart of tips by day of week: Bar chart: length/count; category; color; Presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent. The bars can be plotted vertically or horizontally. A bar graph shows comparisons among discrete categories. One axis of the chart shows the specific ...
In a histogram, each bin is for a different range of values, so altogether the histogram illustrates the distribution of values. But in a bar chart, each bar is for a different category of observations (e.g., each bar might be for a different population), so altogether the bar chart can be used to compare different categories.
A Pareto chart is a type of chart that contains both bars and a line graph, where individual values are represented in descending order by bars, and the cumulative total is represented by the line. The chart is named for the Pareto principle , which, in turn, derives its name from Vilfredo Pareto , a noted Italian economist.
