Natural language interface for building data visualizations, including cascading edits to filter expressions

1. A method, comprising:

at a computing device coupled with a display, the computing device having one or more processors and memory storing one or more programs configured for execution by the one or more processors:

displaying a graphical user interface on the display;

receiving, from a user, a natural language input that specifies a filter, including a first data field, a relation, and a first comparison value;

displaying the natural language input in an input box in the graphical user interface;

receiving, from the user, a user input, in the input box, to replace the first data field in the filter with a second data field;

in response to receiving the user input, automatically replacing, within the input box, the first comparison value with a second comparison value, wherein:

the second comparison value corresponds to a data type of the second data field;

the second comparison value is included in a domain of the second data field; and

the second comparison value is selected based on a sampling of data values for the second data field; and

displaying, on the graphical user interface, an updated data visualization according to the updated filter.

2. The method of claim 1 , further comprising in response to receiving the user input, updating the relation based on the data type of the second data field.

3. The method of claim 1 , wherein a domain of the first data field includes the first comparison value.

4. The method of claim 1 , wherein the data type of the second data field is different from a data type of the first data field.

5. The method of claim 4 , wherein the first data field has a quantitative data type and the second data field has a categorical data type.

6. The method of claim 4 , wherein the first data field has a categorical data type and the second data field has a quantitative data type.

7. The method of claim 4 , wherein the first data field has a measure data type and the second data field has a dimension data type.

8. The method of claim 4 , wherein the first data field has a dimension data type and the second data field has a measure data type.

9. The method of claim 1 , further comprising, before receiving the update to the filter specification, displaying, on the graphical user interface, an initial data visualization, distinct from the updated data visualization, which applies the specified filter.

10. A computing device, coupled with a display, comprising:

one or more processors;

memory storing one or more programs configured for execution by the one or more processors, the one or more programs including instructions for:

displaying a graphical user interface on the display;

receiving, from a user, a natural language input that specifies a filter, including a first data field, a relation, and a first comparison value;

displaying the natural language input in an input box in the graphical user interface;

receiving, from the user, a user input, in the input box, to replace the first data field in the filter with a second data field;

in response to receiving the user input, automatically replacing, within the input box, the first comparison value with a second comparison value, wherein:

the second comparison value corresponds to a data type of the second data field;

the second comparison value is included in a domain of the second data field; and

the second comparison value is selected based on a sampling of data values for the second data field; and

displaying, on the graphical user interface, an updated data visualization according to the updated filter.

11. The computing device of claim 10 , further comprising in response to receiving the user input, updating the relation based on the data type of the second data field.

12. The computing device of claim 10 , wherein a domain of the first data field includes the first comparison value.

13. The computing device of claim 10 , wherein the data type of the second data field is different from a data type of the first data field.

14. The computing device of claim 13 , wherein the first data field has a quantitative data type and the second data field has a categorical data type.

15. The computing device of claim 13 , wherein the first data field has a categorical data type and the second data field has a quantitative data type.

16. The computing device of claim 10 , further comprising, before receiving the update to the filter specification, displaying, on the graphical user interface, an initial data visualization, distinct from the updated data visualization, which applies the specified filter.

17. A non-transitory computer-readable storage medium storing one or more programs configured for execution by the one or more processors, the one or more programs including instructions for:

displaying a graphical user interface on the display;

receiving, from a user, a natural language input that specifies a filter, including a first data field, a relation, and a first comparison value;

displaying the natural language input in an input box in the graphical user interface;

receiving, from the user, a user input, in the input box, to replace the first data field in the filter with a second data field;

in response to receiving the user input, automatically replacing, within the input box, the first comparison value with a second comparison value, wherein:

the second comparison value corresponds to a data type of the second data field;

the second comparison value is included in a domain of the second data field; and

the second comparison value is selected based on a sampling of data values for the second data field; and

displaying, on the graphical user interface, an updated data visualization according to the updated filter.

18. The computer-readable storage medium of claim 17 , wherein a domain of the first data field includes the first comparison value.
