How do you find the highest value on a map?
Approach
- Iterate the map entry by entry for (Map.Entry entry : map.entrySet()) { // Operations }
- Store the first entry in a reference variable to compare to initially.
- If the current entry’s value is greater than the reference entry’s value, then store the current entry as the reference entry.
What must a data source include to create a Choropleth map?

How to highlight the highest and lowest values for the entire table?
To highlight the highest and lowest values for the entire table, we need to change the addressing to Month of Order Data and Sub-Category. There are at least two ways we can change this. First, from within the view, you can click into the pill with the table calculation (identified with a delta symbol), and click “Edit Table Calculation…”.
How to create a map with one data point?
A map view with one data point is created. From Dimensions, drag ID to Detail on the Marks card. If a warning dialog appears, click Add all members. A lower level of detail is added to the view.
Which is the best map to show ratio?
Choropleth maps are best for showing ratio or aggregated data for polygons. These polygons can be counties, regions, states, or any area or region that can be geocoded in Tableau. They can even be custom territories created in Tableau.
How do you find the highest value in a range?
By comparing the COUNTIF result to 1, we identify the first time the value appears in the range. The AND function ensures that multiple criteria have been met – in the cases above, that the value is the highest/lowest value and it is the first time the value has appeared in the range.
