Query Results for Annual NO2 Concentration - Annual Average Concentration of NO2 (mcg/m3) by County
Query Result Page Options
This option remembers your currently selected filtering criteria and display
options and applies
( ) to all subseqent dataset query requests.
This feature can help you save time and be consistent by automatically applying
your defined selections to other queryable datasets you open.
Restrictions/conditions:
- This features only effects queryable datasets loaded after the apply criteria feature is enabled.
- When a new queryable dataset is loaded, this features does NOT clean/clear any of that dataset's default selected values - it simply supplements the newly loaded dataset's selections with those values captured when the apply criteria feature was enabled.
- When in the builder interface you can override and make additional changes (select or deselect).
- Changes made in the builder interface are not automatically saved to the enabled apply criteria definition. However, once you have a result you can reapply the current critera by using this dialog and pressing the "Reapply" button. If you do not see this button then the apply criteria feature has not been enabled.
- Selections are applied according to what selections are available within that given queryable dataset. For example if your apply criteria is set for years 1999-2015 and the dataset does not have 1999 then only years 2000-2015 will be selected.
- This feature is available immediately and does not require any user login account. However, if you wish to save this definition you will need to have either a free self registered user account or a secure DOH account and be logged in to be able to save your definitions.
- TURNING OFF: These selections will remain in effect for the length of your current session on this site. It is turned off by pressing the "Clear" button.
- TECHNICAL NOTE: The selection's internal dimension names and values MUST match. In some instances a value's title shown to the user will look the same as the dataset's but it is stored internally with a different name or value so they do not match and thus will not be selected. As an end user there is nothing that can be done about this situation because this is something the dataset author must setup. If you see something like this please contact us and report this issue.
One Example:
Doing studies on different datasets like you want to look at different survey datasets for hispanic females for years 2015-2018. You want to always display a county choropleth map and a horizontal bar chart. You make those initial selections, submit your selections, enable this apply criteria feature. From then on, those selections are automatically applied (as much as possible) to all subsequent queryable datasets you open.You are not logged in. To save a query you must be logged in.
