The left-hand side image is an example of a high-low chart comparing the high and low temperatures during January and July, for a number of European cities.

The image below displays the high, low, and midpoint values (when here, the midpoint values represent the mean) of a variable, for measurements taken at different boreholes.

In these charts, the values of one or more data series can be plotted against a continuous variable.

  • X-Y (value axes) high-low chart: This chart type is used to display the high and low values of one or more data series against a continuous variable.
  • X-Y (value axes) range chart: This chart type is used to show the high, low, and midpoint values of one or more data series against a continuous variable.

High-Low-Close and Open-High-Low-Close Charts

These charts show the fluctuations in values of a given item over time, and are commonly used in market analysis.

The image above displays an open-high-low-close chart showing the fluctuations in S&P 500 during 21 days in March and September 94.

The image in the left-hand side displays an X-Y (value axes) range chart showing the high, low, and midpoint values of two data series with increasing depth.
