Behavior

It is possible to produce a bar chart inside a table by adding a column, marking it with the text “Chart Legend” and adding a DimensionGroup of type bars.

...

Usage

• Add a new “Chart Legend” column in a table style to allow for horizontal bar charts to be inserted

...

• “Chart Legend” text should be on the level of the column groups. The chart legend is then produced by merging the column group and column cells together

...

The bars themselves are generated by placing in the chart column for each row a table which consists of two cells. One cell is the filled out bar and the other is basically the padding.

The bars start with the height defined in the configuration file setting tablechart.barheightInPt and shrink proportionally until tablechart.minimumbarheightInPt is reached.

The axis can be styled by setting tablechart.axisbordercolor and tablechart.axisborderwidth in the configuration file.

...

• .

  • If any chart column does not have a name set or is set to empty string (““), the chart legend will not be generated

• Bar coloring follows the defined theme. Once all colors are used, they start cycling.

• The column width can be set by setting tableChart.chartColumnWidth in the metadata (see below on how to set metadata) or the DimensionGroup.width property

• The last column width need to be set in percent

Table Style Metadata

Table Style Metadata Parameter	Explanation	Default	Visualization
tableChart.axisBorderColor	Defines the color of the border line between negative and positive bar chart. This value is set in Hex.	#000000 (Black)
tableChart.axisBorderWidth	Defines the width of the border line between negative and positive bar chart. This value is set in pt.	0.5 pt
tableChart.barHeightInPt	Defines the desired bar height in the chart. This value is only effective if no resizing (proportional shrinking) of the chart is required. This value is set in pt.	8.50394pt (0.3 cm)
tableChart.minimumAxisWidthInMM	Defines the minimal width of the negative and positive bar chart side. This value is set in mm.	4 mm	Image Added
tableChart.minimumBarHeightInPt	Defines the minimum bar height in the chart. This value is guaranteed and will force the cell height to grow if necessary. This value is set in pt.	4.25197 pt (0.15 cm)
tableChart.minimumChartPaddingInPt (new)	Defines the minimal vertical padding for the bar chart. Notes: Padding is achieved by adding additional row on top and bottom of the chart Effect of parameter only visible if: #bars*minimumBarHeightInPt + 2*minimumChartPaddingInPt > highest_cell_in_row Bar Chart placement follows alignment settings of word channel (should ideally be set to centered). Important for cases where the effect is not visible. If minimumChartPaddingInPt is set to 0 or the row’s height is set to Exactly, this parameter will have no effect This value is set in pt.	Depends	Image AddedImage Added
chartColumnWidth	Defines string aliases to be used for the otherwise numeric chartWidth BB parameter. This value of chartColumnWidth is an object from string to number, where the number is in % (from 2-100). ex.: Code Block chartColumnWidth: { "narrow": 20, "standard": 48, "wide": 60 } Note: Many table-chart BBs support the parameter chartWidth, albeit only via JSON code-view.

Behavior

The axis is positioned based on the data in the abstract report. There are four positions with a distance of 25% of the column width of eachother. If there are no negative values, the axis is placed at position 0 (i.e. to the left). If there are only negative values smaller than 25% of the total, the axis is positioned at position 1 (which is at 25% of the column width) and so forth. Please see the the examples section for concrete applications of this principle.

The formatting of the cell with the text “Chart Legend” is copied and used for formatting the produced chart legend. It is also possible to specify left and right margins in each cell beneath the “Chart Legend” cell.

The column width can be set by either setting the metadata (the JSON comment), the DimensionGroup.width property or if nothing is set, the actual column width in percent in the table style.

The chart legend is not created if at least one chart column does not have its name set or if it is set to an empty string.
