Scatter-plots: Exploring relations across two numeric attributes
A scatter-plot helps you identify trends across two numeric attributes. Each data record becomes a point (dot) placed in a position based on the record values of two numeric attributes. The point appears on a higher position as its vertical axis attribute gets larger. Likewise, a higher value on horizontal axis attribute places the record point towards the right-end side.
Watch the short clip above to see how you can compare development indicators of over 200 countries using the Keshif scatter-plot view. We included some categorical attributes of the countries (region and income group) on the left panel to enrich the analysis by highlighting, filtering, and comparison.
Creating a scatterplot
To create a Keshif scatter-plot, insert records into the record display (middle panel), and click “ Scatter” icon.
Note: The scatterplot option is available only if you have two or more numeric attributes.
Changing compared attributes (scatterplot axes)
Click on the axis attribute name to see the list of attribute options which can be used as the axis.
You can swap the vertical/horizontal axes by clicking the swap icon on lower-left corner of the scatter plot.
Note: the axis options can be numeric, time-series, or timestamp attributes.
Interacting with records (dots): Highlighting a record and viewing record details
Move the mouse over an individual record point to highlight its values across the dashboard.
Click on a record point to see its record detail panel. For demonstration, see the clip above.
Enriching Scatter-plot Analysis
You can enrich your analysis of two numeric attributes by adding another numeric attribute to analysis (as the record-point color), or by grouping records based on selected categories (which assigns unique colors per record group).
Exploring an additional attribute by color
Note: If you choose a time-series variable, you can navigate the time by selecting among any of the time-key, or auto-animating from past to forward.
Exploring Categories on Scatterplots with aggregate selection: Highlight/filter/compare
You can lock different categories (group of records) and analyze the differences and patterns across multiple groups, as Keshif assigns a unique color for each group of record-points.
Adjusting the point size on the map
- To increase point size, click the outer border of the dot in the color legend area.
- To decrease point size, click the inner disc of the dot in the color legend area.
Filtering data using the scatter-plot
Keshif offers a "filtering" mode for mouse interaction.
- To filter: Left-click & drag mouse
- To highlight: Press shift-key, hold key, drag mouse
- To set a compared group: Highlight + left-clic
