Chart

The Chart widget allows you to display data (from an external CSV file or manual input) in a chart that is easy to read and understand.

Settings

There are 6 chart types available:

  • Area chart: shows up to 3 series in an overlapping (non-stacked) area chart;
  • Line chart: shows up to 3 series as lines;
  • Bar chart: shows up to 3 series as horizontal bars;
  • Column chart: shows up to 3 series as vertical bars;
  • Pie chart: shows one data series as a pie chart;
  • Map chart: shows one data series as a map overlay, showing values per country.

You can configure the widget to render with or without legend and borders. The legend shows a total and a trend per data series.

Data input:

You can either add data manually or by external CSV file. Manual entry is convenient for simple charts that you do not need to update often. Using an external CSV as the data source allows you to display live data charts.

The Chart widget expects you to provide a publicly accessible CSV file, with the following characteristics:

  • Columns are separated with a comma (,);
  • Values that contain commas or other special characters are quoted using double quotes (");
  • The first line contains column headers
  • The first column contains labels
  • The following columns (max. 3) should contain numeric data values;
  • CSV files can contain at most 250 rows.

The map chart type expects the first column to contain either:

  • Country names in English (e.g. Belgium, Australia, United States);
  • A 2-letter country code (according to ISO 3166-1 alpha 2)
