Min/Max Chart

A Min/Max chart shows the Minimum, Maximum, and Average values of a selected measure. These charts are best used for showing the range of a measure, like minimum and maximum temperature recorded for each day of the month. The most common use cases are for healthcare measurements (temperature, heart rate, oxygen levels, etc), or for “sensor” use-case for IoT devices where the chart creator’s main interest is to show the Min/Avg/Max each minute or hour, for example.

Creating a Min/Max Chart

To create a Min/Max Chart, you need one column as Category and another one as Values. In the example below, we want to show the minimum, maximum, and average wine prices for each country in the data. We drag and drop country as Category and price as Values. In the General section, we checked the Display Average box and decided to hide the labels in the Styles section to make the chart clearer to read. We can see the minimum, maximum, and average price in the tooltip when hovering over a data point.

Styling the Min/Max Chart

In the Configuration Panel on the right of the Chart Builder, you can style different aspects of your chart.

General

The General section is available for all chart types, and the options vary depending on the chart selected. For more information on the options, see General Chart Settings.

Styles

The Styles section enables you to control various visual elements of the charts, such as colors, labels, and more. It is available for most chart types, and the options vary depending on the chart selected. For a glossary of all styles, see Styles. Style options specific to this chart are listed below.

  • Color Type
    • Single - all data points are the same color.
      • Color - change the color of the data points.
    • By category - each data point is colored based on its category.
      • Theme - set one of the predetermined themes for a more unified look of your charts.
      • Match colors across charts - unify the colors of each categorical value throughout the page and application.
  • Axis Labels - Show or hide the labels of the axes.
  • Orientation - Choose between the vertical or horizontal orientation of the chart.
  • Values axis (typically y axis)
    • Label - give the axis a custom label.
    • Values - show or hide values on the axis.
    • Values Rotation - if value labels are enabled, decide how you want them to be displayed. You can use this option to avoid overlapping labels.
    • Format - set the format of the values choosing between Default, Abbreviated, Decimal (set the number of decimal points), Currency (choose the currency from the drop-down menu and set the number of decimal points), Percentage (set the number of decimal points), Scientific. Values can also be formatted from the Values column pill.
    • Scale Type - the default scale type is Linear; however, a linear scale is not appropriate for data that is spread over a wide range. Use the Logarithmic scale to display numerical data over a wide range of values in a compact way.
    • Min Range - set the minimum value for the axis.
    • Max Range - set the maximum value for the axis.
    • Steps - Depending on how wide the axis range is, the default configuration could display a lot of tick marks, making it hard to read or analyze the chart. Intervals are set to Auto by default, meaning the chart will calculate the appropriate intervals based on the axis scale range and the dataset values. min-max It’s important to keep in mind that when the axis range is vast (e.g., 0 - 10,000,000), setting the “Steps” option to 1 will create 10 million tick marks, causing performance issues on the chart and probably blocking the browser. To avoid this situation, the chart will ignore the defined value and fall back to automatic mode.
  • Line Thickness - set the line as thin, normal, or bold.
  • Line Style- display the line in solid, dashed, or dotted style.
  • Symbol - Users can choose between 7 different types of symbol styles (Circle, Square, Diamond, Triangle Down, Triangle Up, X, Cross) depending on the visualization they need.
  • Fill - decide if you want the symbols on the chart to be filled or outlined.
  • Line Opacity - Set the degree of the line opacity from solid to more opaque to see the map behind it better.
  • Data Labels - show or hide the Value labels of your data points.
    • Borders - display your values within a frame.

Sorting

Like all XY Charts, you can sort by either the category or aggregated values from the column pills. If the column is not included in the chart, go to the Sorting section of the Configuration Panel and pick your desired column from the dropdown, and select the sorting direction.

For more information, see Sorting.

Layers

Add a Trend Line or a Reference Line to your chart to allow users to visually compare the data against some set trend or reference value.

Format

The Small Multiples feature is available in all XY Charts. You can apply Conditional Formatting to your Min/Max Chart.

Filters

You can also add Filters to your data by expanding the Filters section in the configuration panel or by clicking on the Filters button in the toolbar above the canvas. Filters that are created in the Chart Builder are hidden from End Users. These types of filters can’t be edited or interacted with in the view mode. For more information, see Filters.
