Bar Chart

A bar chart will draw categories and values in a familiar bar-layout. The bar chart will require you to choose the following selections:

Category: a text field. These will be the labels on the bars.
Value: a numeric field. This will be the height of the bars.
Group: Optionally, a second textual field. When ``Grouping'' is enabled in the advanced settings, the group can be used to draw a stacked bar chart, with several groups per category.

Examples

Simple Bar Chart

MATCH (p:Person)-[e]->(m:Movie)
RETURN m.title as Title, COUNT(p) as People

Stacked Bar Chart

Match (n:Person)-[e]->(m:Movie)
RETURN m.title, COUNT(p) as People, type(e) as Role

Advanced Settings

Name	Type	Default Value	Description
Show Legend	on/off	off	If enabled, shows a legend at the top right of the visualization.
Grouping	on/off	off	If enabled, lets users specify a third, grouping field. This is used to distinguish between different groups in the stacked bar chart.
Value Scale	List	linear	When set to symlog, uses a Symmetric logarithmic scale instead of the default linear scale.
Min Value	Number	auto	If not set to ``auto'', this variable is minimum value for the bar chart.
Max Value	Number	auto	If not set to ``auto'', this variable is the maximum value for the bar chart.
Group Mode	List	stacked	This setting determines how different groups are visualized when grouping is enabled. If set to stacked, different groups of the same category are stacked on top of each other. If set to grouped, they are placed alongside each other.
Layout	List	vertical	Whether to use a vertical or horizontal bar chart layout.
Color Scheme	List		The color scheme to use for the category groups. Colors are assigned automatically (consequitevely) to the different groups returned by the Cypher query.

Skip label on width (px)	number	0	Skip label if bar width is lower than provided value, ignored if 0.
Skip label on height (px)	number	0	Skip label if bar height is lower than provided value, ignored if 0.
Custom label position	off/top/bottom	off	Allow user to place label out of the bar. This will override any other label configuration.
Label Rotation (degrees)	number	45	the angle at which the bar labels are rotated.
Margin Left (px)	number	50	The margin in pixels on the left side of the visualization.
Margin Right (px)	number	24	The margin in pixels on the right side of the visualization.
Margin Top (px)	number	24	The margin in pixels on the top side of the visualization.
Margin Bottom (px)	number	40	The margin in pixels on the bottom side of the visualization.
Legend Width (px)	number	128	The width in pixels of each legend label on top of the visualization (if enabled).
Hide Selections	on/off	off	If enabled, hides the property selector (footer of the visualization).
Auto-run query	on/off	on	when activated automatically runs the query when the report is displayed. When set to `off', the query is displayed and will need to be executed manually.
