Using the lasso tool on the map to filter data

The visual has been designed so that clicking on a point or polygon on the map displays a pop-up with additional useful information about that location instead of filtering data in other visuals on the page.

The lasso tool allows you to filter the data on other visuals based on a selection taken from the map.

1

Select the lasso tool by clicking on the lasso icon in the top right of the map.

Your cursor should change shape once the lasso button has been clicked.

2

Draw a ‘lasso’ by holding down the left mouse button and dragging the cursor around all the points / polygons that you want to filter the other visualisations on the page by.

A cyan coloured shape will be created during the process.

3

Once you’re happy with your selection, release the left mouse button.

Any points/polygons completely within the boundaries of the lasso shape created will now be highlighted cyan and the other visualisations on the page will be update reflecting the selection made.

Maximum number of data points

The lasso tool can only select up to 500 different data points on the map at a time to ensure adequate performance.
