Reactive graphical display of real-time values
Data values for various items are visualized in real-time or near real-time using radial-based techniques to produce data visualizations bearing some resemblance to, for example, pie charts, radial charts, etc. The data values are shown using indicators that encircle, or at least partially encircle, a central point. One or more characteristics of the indicator reflect the value that corresponds to the indicator. The characteristics may include, for instance, the color of the indicator and/or the distance of the indicator (or more specifically, a given point on the indicator) from the central point. The characteristics of the indicators change over time, in accordance with changes in the current values of the data items. A variety of indicators may be used, including, without limitation, points, icons, pie “wedges,” filled or partially-filled sectors of an ellipse or semi-circle, arcs or lines that span between the sides of such sectors, and so forth.
1. A method, comprising:
receiving a set of data values from one or more data sources;
causing display of the set of data values in a radial graph comprising a semi-circular region having sectors with a common vertex, wherein each sector includes a radial projection that fills the sector extending from a first level in the sector to a second level in the sector determined by mapping a corresponding data value in the set of data values to a fixed scale for the graph; and
upon receiving substantially real-time updates to one or more data values in the set of data values that correspond to a particular radial projection, dynamically modifying the fill of that radial projection within the corresponding sector to a level that reflects the changes in the one or more data values while maintaining the fixed scale for the radial graph.
2. The method of claim 1 , wherein a radial projection for a sector comprises a sub-sector having a radius representing the corresponding data value for the radial projection.

4. The method of claim 1 , further comprising:
displaying one or more peak-value indicators for radial projections in the radial graph; and
wherein a peak-value indicator for a radial projection comprises a radial arc overlaid on an associated sector at a furthest radial distance reached by the radial projection during a preceding time interval.
5. The method of claim 1 , wherein a radial projection is displayed using one or more colors that are selected based on the corresponding data value for the radial projection.

7. The method of claim 1 , wherein a radial projection is displayed using one or more colors that are selected based on the corresponding data value for the radial projection, and wherein the one or more colors are further selected based on whether the corresponding data value exceeds one or more threshold values.

9. The method of claim 1 , wherein displaying the radial graph includes displaying one or more data-selection controls that enable a user to select the set of data values to be displayed by specifying:
one or more data sources for the set of data values; and
one or more types of data to display from the one or more data sources.
10. The method of claim 1 , wherein a boundary of the semi-circular region is not displayed except to an extent of overlap with sectors or radial projections.
11. The method of claim 1 , wherein a boundary of a sector is not displayed except to an extent of overlap with a radial projection.
12. The method of claim 1 , wherein an entirety of the semi-circular region is included in the sectors.
13. The method of claim 1 , wherein an entirety of the semi-circular region is not included in the sectors.
14. The method of claim 1 , wherein each side of each sector is adjacent to another one of the sectors.
15. The method of claim 1 , wherein at least one side of one sector is not adjacent to another one of the sectors.
16. One or more non-transitory computer-readable storage media, storing one or more sequences of instructions, which when executed by one or more processors cause performance of:
receiving a set of data values from one or more data sources;
causing display of the set of data values in a radial graph comprising a semi-circular region having sectors with a common vertex, wherein each sector includes a radial projection that fills the sector extending from a first level in the sector to a second level in the sector determined by mapping a corresponding data value in the set of data values to a fixed scale for the graph; and
upon receiving substantially real-time updates to one or more data values in the set of data values that correspond to a particular radial projection, dynamically modifying the fill of that radial projection within the corresponding sector to a level that reflects the changes in the one or more data values while maintaining the fixed scale for the radial graph.
17. The one or more non-transitory computer-readable storage media of claim 16 , wherein a radial projection for a sector comprises a sub-sector having a radius representing the corresponding data value for the radial projection.
18. The one or more non-transitory computer-readable storage media of claim 16 , where the method further comprises displaying one or more peak-value indicators for radial projections in the radial graph, wherein a peak-value indicator indicates a peak value represented by a corresponding radial projection during a preceding time interval.
19. The one or more non-transitory computer-readable storage media of claim 16 , further comprising:
displaying one or more peak-value indicators for radial projections in the radial graph; and
