220.127.116.11 The (Plot Details) Spacing Tab
The controls on the Spacing tab are dependent on the current data plot type. The following reference section reviews all the possible controls on this tab.
| In Scatter or Line+Symbol graph
|| In 2D Columns or 2D Bars graph
| In Heatmap plot
|| In Box / Histogram plot
Gap Between....(in %)
This combination box value controls the spacing between the columns, bars, or boxes for each X value, in units of % of the width of the columns, bars, or boxes at each X value. The control supports keyboard entry or selecting from the drop-down list.
The default value is 20; accepted values range from 0 to 100. If the input value is not an integer, it will be rounded up to the next integer.
Note: If Subgrouping is turned on for a box chart or histogram, you can edit the Gap Between Subgroups and Gap Within Subgroups (%, Negative for Overlap). Please note, the Gap Within Subgroups(%, Negative for Overlap) accepts negative value which will make the columns/bars/boxes in same subgroup overlapped.
Overlap (%, Negative for Gap)
This combo box is available in following two cases:
- if the data plot is part of grouped plots.
- if the data plot is in the first layer of a multi-layer column/bar graph which enables the gap across layers.
Type or select a value from this combination box. The value is the percentage of column/bar overlapped at a given X value. The percentage value is the relative ratio between the gap/overlap and the column/bar width. A negative value means space(gap) between columns/bars. If the value is 0, there is no gap or overlap.
The default value is 0. The accepted range is from -100 to 100.
Gap between Bars from Different Panels(in %)
For a multiple-panel plot, such as a trellis plot, you can overlap the panels(which means combine the multiple panels to one single panel) by checking the Overlap Panels check box in the Panel tab.
If you do this for a column/bar trellis plot, you can use Gap between Bars from Different Panel edit box in the Spacing tab to add gap between bars from different panels to avoid them from overlapping.
Width (in %)
Specify a dataset to control column/bar width.
Select a column (dataset) from the drop-down list. Dataset values determine the relative column/bar width, in combination with Gap Between and Overlap settings. Values are multiplied by the Scaling Factor(see below).
Accepted values must be greater than or equal to 0. When Width (in %) is 0, the column/bar displays as a vertical/horizontal line.
Use this combination box to define the scaling factor for values in the Width (in %) column.
Enter a Scaling Factor by typing or choosing from the drop-down list. The value can be any positive rational number or 0.
When the Factor is 0, the values in the Width (in %) column determine bar width in terms of X axis scale values .
Specify whether to divide the columns/bars and scatter plots into subsets; and if dividing into subsets, By Size or By Column (of categorical values). The Subset group is not available for all grouped plots. For instance, these controls are available for grouped column or scatter plots but are dimmed for Trellis plots, in which grouping is controlled on the Panel tab.
Specifically, the Subset group is available under these conditions:
- The plot has automatically assigned X data (The data plot is named as <autoX, Y> in the Plot Details dialog). There are a couple of situations where X values are automatically assigned but in this context (e.g. a grouped column plot or scatter plot), one or more Group Column(s) are used to construct the X axis "scale".
- ... and Enable Panel is turned off (on Panel tab, None is selected for both directions).
- The plot has arbitrary X data, but the Type of X axis tick label is set as Text from Dataset, and the dataset used to define tick labels is the X data.
| Enable Subset
- None: Do NOT divide the columns into subsets. Note that in this example column plot, columns are evenly-spaced.
- By Size: Divide the columns into subsets by a specifying the subset size (generally useful for balanced grouped plots). If Subset Size is set to 0, subset is not used. In the following example, Subset Size = 4 and you can see that there is a larger gap between each group of four columns.
- By Column: Divide the columns into subsets by categorical values in a worksheet column (especially useful for an unbalanced grouped plots). Specify your worksheet column using the drop-down list. Note in the following examples, the effect of subset on column grouping (major grid lines turned on for clarity).
| Gap Between Subsets(%)
||If Subset Size is not 0, you can specify the Gap Between Subsets (%) by either selecting a number from the drop-down list or you can enter a value directly. This is a percentage of the width of the columns/bars.
|Note: When subsets are enabled, tick label tables like those shown in the grouped column charts above, are structured using a combination of Subset controls and the Merge Labels setting on the Tick Labels tab, Table sub-tab of the X Axis dialog box.
For instance, in the following example, Subset was set By Column = Genotype and you can see the effect of the Merge Labels setting on Treatment row tick labels.
For more information on control of tick labels, see The (Axis dialog box) Tick Labels tab.
Gap Between Cells in X/Y Direction (%)
These options are only for Heatmap plot. These sliders are used to control the width of the spacing on X/Y direction, on a scale from 0 to 100.
- When the gap in one direction:
- 0 means there are no spacing between the cells in that direction, 100 means the cells will be displayed as lines in that direction.
- When the gaps in both direction:
- The calculation method of gap value is different from above. The cell value is not independent for X or Y. In both two direction, 100% cell value=(cell width+cell height)/2.
For example, if you set Gap Between Cells in X =30, Gap Between Cells in Y=50
the actual X direction gap value=(cell width+cell height)/2*30%
the actual Y direction gap value=(cell width+cell height)/2*50%
