Bug ID: 160411
Summary: Support an "XY+Value" scatter plot chart type
Product: LibreOffice
Version: Inherited From OOo
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: enhancement
Priority: medium
Component: Calc
Assignee: [email protected]
Reporter: [email protected]
Calc offers an XY ("scatter") chart type: A data series is a pair of columns,
containing X and Y coordinates respectively; and it results in points on the
chart area.
I would like to use the X and Y coordinates for placing some label, or
numerical value, at different positions on the chart area. In this chart type,
3 columns will be necessary (for a single data series): X, Y and Value or
Label.
This chart type will have several variants, depending on what happens at each
(x,y) point:
* Value is placed as label only, and point indicator is independent of it
* Value is used as radius of the dot/disc at each point (or a scaling factor of
the shape, if it's a different point)
* Value is used as the point on a color gradient of the dot or disc or shape at
each point.
Other choices might be similar to those of XY charts:
* Which shape to use for the different points of a data series
* What color gradient to use for the dots/discs/shapes; this could be done
similarly to the selection of color gradients for conditional formatting.
* Place a dot at each point Yes/No
* Draw a line from point to point Yes/No
* (related to bug 160398) Whether to use some background image (vectorized or
raster) - such as a map
