Abstract

A system and method of facilitating data visualization provides for receiving a user response to a data entry interface via a network, where the user response defines a first data set and a second data set. Data points in the first and second data sets include dependent variable values. A first chart is generated based on the first data set and a second chart is generated based on the second data set. An appearance of the second chart is modified if a user-selected area of the first chart corresponds to a first data point in the first data set and the first data point has a predetermined relationship with a second data point in the second data set.

Claims

receiving a user-controlled position of a cursor in the first chart, the position of the cursor corresponding to a first data point in the first data set;

determining a correspondence relationship between the first data point and at least one data point in the second data set; and

modifying an appearance of the second chart to highlight the correspondence relationship between the at least one second data point in the second chart and the first data point as determined solely by the user-controlled position of the cursor in the first chart.

2. The method of claim 1 further including simultaneously generating a first highlighted area in the first chart and a second highlighted area in the second chart, the first highlighted area corresponding to the first data point and the second highlighted area corresponding to the at least one second data point, the highlighting being automatically performed by the computing device and displayed on the display unit.

3. The method of claim 2 further including locating the at least one second data point in the second data set based on a determination of whether the first data point has the correspondence relationship with the at least one second data point.

4. The method of claim 3 further including:

determining whether the first data point has an independent variable value that matches an independent variable value of the at least one second data point by comparing an independent variable value of the first data point with independent variable values of the second data set; and

automatically highlighting the independent variable value of the at least one second data point.

5. The method of claim 3 further including:

determining whether the first data point has a dependent variable value that matches a dependent variable value of the at least one second data point by comparing a dependent variable value of first data point with dependent variable values of the second data set; and

automatically highlighting the dependent variable value of the at least one second data point.

6. The method of claim 3 further including:

determining whether the first data point has a dependent variable label that matches an independent variable value of the at least one second data point by comparing a dependent

variable data label of first data point with independent values of the second data set; and

automatically highlighting the independent variable value of the second data point.

7. The method of claim 3 further including:

locating additional data points in the second set of data based on a determination of whether the first data point corresponds with the additional data points by comparing an independent value of first data point with independent value on the second data set; and

automatically generating highlighted areas for each of the additional data points.

8. The method of claim 2 further including determining that the user has positioned a cursor within a predefined distance proximate to the first highlighted area.

9. The method of claim 1 further including transmitting the charts to the data entry interface via the network.

10. The method of claim 1 further including:

generating a chart type selection interface;

transmitting the chart type selection interface to the data entry interface via the network;

generating the charts based on a user response to the chart type selection interface; and

storing the user response to the chart type selection interface to a database.

11. The method of claim 10 wherein the charts include at least one of a pie chart, a bar chart, and a table.

12. The method of claim 10 further including associating a write privilege with the user, the write privilege enabling the user to modify data stored in the database.

13. The method of claim 10 further including:

generating a color selection interface;

transmitting the color selection interface to the data entry interface via the network;

generating the chart based on a user response to the color selection interface; and

storing the user response to the color selection interface to the database.

14. The method of claim 1 further including:

generating the data entry interface; and

transmitting the data entry interface to the data entry interface via the network.

15. The method of claim 1 further including storing the first data set and the second data set to a database.

16. A method of facilitating data visualization at a display unit of a computing device, the method comprising:

receiving a user response to a data entry interface via a computer network, the user response defining a first data set and a second data set, the first and second data sets including dependent variable values;

generating a first chart based on the first data set and a second chart based on the second data set;

storing the first data set and the second data set to a database;

receiving a user selection of an area of the first chart solely based on a position of a cursor;

determining whether the selected area corresponds to a first data point in the first set of data set;

generating a first highlighted area in the first chart if the selected area corresponds to the first data point;

locating a second data point in the second data set based on a determination of whether the first data point has a predetermined relationship with the second data point; and

simultaneously generating a second highlighted area in the second chart if the first data point has the predetermined relationship with the second data point, the second highlighted area corresponding to the second data point.

17. The method of claim 16 further including:

determining whether the first data point has an independent variable value that matches an independent variable value of the second data point; and

highlighting the independent variable value of the second data point.

18. The method of claim 16 further including:

determining whether the first data point has a dependent variable value that matches a dependent variable value of the second data point; and

highlighting the dependent variable value of the second data point.

19. The method of claim 16 further including:

determining whether the first data point has a dependent variable label that matches an independent variable value of the second data point; and
