Create a heat map chart in everviz

Follow the steps in this article to create a heat map chart in everviz.

Heat map charts are great for seeing how relative value of one datum compared to others in a table. A colour represents each datum and the shade of that colour denotes its magnitude. In everviz, a darker shade means a higher magnitude, or a datum with a higher value relative to others in the data table, while a lighter shade shows the opposite.

The example we’ll create lets us see the quarterly performance of a sales team as different shades, with darker shades representing better performance and lighter shades representing lower performance. This will let us quickly identify superstar salesmen and those who need to improve their performance.

To create a heat map chart:

  • Launch the project wizard and select Chart to launch the chart wizard
  • Select Heat map from the Chart type section to the left of the chart wizard’s screen. Notice that the preview pane changes to reflect the chart type you’ve chosen
  • Click Next to move to the Data step where you can enter the data for your chart
  • Click the top-left cell (A1) in the data table and press CTRL+A to select all the data in it
  • Press the delete key to remove the example data
  • Copy this example data and paste it into the data table at the top-left cell (A1). You’ll see the newly added data reflected in the preview chart
  • Click Next to move to the Design screen where you can choose a theme for your chart. Click an available theme to see how it looks, or stick with the default theme
  • Click Next to move to the Text & Annotations screen where you can add contextual information to your chart, such as a title, axis labels and a caption
  • Click Next to move to the Save or Publish screen where you can save your chart for later amendment or use, or publish your chart
  • Alternatively, you can click the Continue in Editor button to edit the chart further with more granular options
