Abstract

A “Charting Animator” enhances computer-based charting/graphing systems by rendering dynamic animations of chart displays. In general, when a user changes from one chart type to another, adds new data to a chart, or changes, sorts or deletes data, a new chart is generated to replace the old chart. Conventional charting systems simply replace the existing chart with the new chart. In contrast to conventional systems, the Charting Animator renders animated transitions that dynamically morph the original chart into the new chart. Consequently, these animations avoid abrupt changes that can disorient users. Examples of these animations include animating changes from one chart family to another (e.g., changing from a “Bar Chart” to a “Pie Chart”), animating changes from one chart type within a chart family to another chart type (e.g., changing 2D Bar Charts to 3D Bar Charts or Stacked Bar Charts), animating data changes, animating sorts, etc.

Claims

1. A method for animating changes to charts, comprising steps for:

receiving at least one data set comprising a plurality of data elements;

automatically rendering a first chart having a user selected first chart type from data elements of the at least one data set;

wherein the chart includes a plurality of chart elements that provide graphical representations of corresponding data elements.

displaying the first chart on a display device;

changing one or more of the data elements of the at least one data set; and

rendering an animation on the display device that morphs the first chart into a second chart, wherein the second chart is rendered from the data elements of the at least one data set, including the one or more changed data elements.

2. The method of claim 1 wherein changing one or more of the data elements of the at least one data set further comprises steps for comprises directly editing one or more of the data elements via a graphical user interface.

3. The method of claim 1 wherein changing one or more of the data elements of the at least one data set further comprises steps for:

using a graphical user interface to graphically change one or more of the chart elements; and

wherein corresponding data elements are automatically changed to correspond to the changes to the one or more chart elements.

4. The method of claim 1 wherein changing one or more of the data elements of the at least one data set further comprises steps for:

adding at least one new data element to the at least one data set; and

wherein rendering the animation on the display device that morphs the first chart into the second chart comprises animating an addition of one or more new chart elements corresponding to the at least one new data element.

5. The method of claim 1 wherein changing one or more of the data elements of the at least one data set further comprises steps for:

deleting at least one data element from the at least one data set; and

wherein rendering the animation on the display device that morphs the first chart into the second chart comprises animating a deletion of one or more chart elements corresponding to the at least one deleted data element.

6. The method of claim 1 wherein changing one or more of the data elements of the at least one data set further comprises steps for:

sorting one or more of the data elements; and

wherein rendering the animation on the display device that morphs the first chart into the second chart comprises animating a graphical sort of the chart elements corresponding to the sorting of the data elements.

7. The method of claim 1 wherein the user selected first chart type is one of the data elements, and wherein changing one or more of the data elements of the at least one data set further comprises steps for:

selecting a second chart type; and

wherein rendering the animation on the display device that morphs the first chart into the second chart comprises morphing the first chart type into the second chart type.

8. A computer readable medium having computer executable instructions stored thereon for rendering charts on a display device, comprising instructions for:

entering a set of data elements;

selecting a first chart type from a list of available chart types;

rendering a first chart of the selected first chart type on a display device as a function of the set of data elements, said first chart being composed of a plurality of chart elements each chart element providing a graphical representation of one or more of the data values;

modifying one or more of the data elements via a graphical user interface; and

rendering an animated transition that morphs the first chart into a second chart, said second chart being rendered as a function of the set of data elements as changed by modifying one or more of the data elements.

9. The computer readable medium of claim 8 wherein modifying one or more of the data elements comprises directly editing values of the one or more data elements via the graphical user interface.

10. The computer readable medium of claim 8 wherein modifying one or more of the data elements comprises instructions for manually resizing one or more of the chart elements via the graphical user interface, and wherein any data values associated with a resized chart element are automatically changed to correspond to the resized chart element.

11. The computer readable medium of claim 8 wherein modifying one or more of the data elements comprises instructions for manually moving one or more of the chart elements to a new position within the first chart via the graphical user interface, and wherein any data values associated with a moved chart element is automatically sorted to correspond to the new position of the moved chart element.

12. The computer readable medium of claim 8 wherein modifying one or more of the data elements comprises instructions for manually resizing one or more of the chart elements via the graphical user interface, and wherein any data values associated with a resized chart element are automatically changed to correspond to the resized chart element.

13. The computer readable medium of claim 8 wherein modifying one or more of the data elements comprises instructions for manually deleting one or more of the chart elements via the graphical user interface, and wherein any data values associated with a deleted chart element are automatically deleted from the set of data elements.

14. The computer readable medium of claim 8 wherein modifying one or more of the data elements comprises instructions for manually adding one or more new chart elements via the graphical user interface, and wherein new data values corresponding to the new chart elements are automatically added to the set of data elements.

15. A system for rendering charts, comprising using a computing device for:

receiving a set of data elements, said data elements representing values for defining graphical elements of a chart;

providing a user interface for selecting a first chart type;

rendering a first chart of the selected chart type on a display device using the set of data elements to define each graphical element of the first chart;

changing one or more parameters of the first chart;

determining an appearance of a second chart based on the changed parameters of the first chart; and

rendering an animated transition on the display device that morphs the first chart into the appearance of the second chart over a predefined period of time.

16. The system of claim 15 wherein changing one or more parameters of the first chart comprises editing one or more of the data elements via the user interface.

17. The system of claim 15 wherein changing one or more parameters of the first chart comprises selecting a second chart type.

18. The system of claim 15 wherein changing one or more parameters of the first chart comprises resizing one or more of the graphical elements of the first chart by interacting with graphical elements of the first chart via the user interface, and wherein any data elements related to any resized graphical elements are automatically modified to correspond to the resized graphical elements.

19. The system of claim 15 wherein changing one or more parameters of the first chart comprises moving a row of graphical elements to a new row of the first chart, and wherein the set of data elements is automatically sorted to correspond to the new row of the moved graphical elements.

20. The system of claim 15 wherein changing one or more parameters of the first chart comprises combining one or more graphical elements of the first chart into a single composite graphical element, and wherein any data elements corresponding to the composite graphical element are combined in the set of data values.
