Customize the chart

To customize the chart view, open/close the tool box by Clicking the "Hammer/Tool" button:


Now you may customize seleted data series idividually or all together:





Scaling


With Autoscale checked, DotChart finds Minimum/Maximum values from all loaded data series and adjusts Y-axis accordingly.

Un-check Autoscale and define Minimum / Maximum manually.

Show / Hide Major grid / Minor grid / Minor Scale / Minor ticks by checking the respective fields.





Select series

To select a single series just click with the mouse into the series.
The selected series will be shown on green hghlighted background:


To select multiple series, keep Ctrl-Key pressed when clicking multiple series.

To select a range, click first series, next last series keeping Shift-Key pressed.

Any subsequent operation with a series, will be applied to all selected series.

If nothing is selected, DotChart assumes you want to modify all series.





Arrange series

You may freely reorder the displayed data series.

Click into a series, and drag it with pressed left mouse button somewhere within the chart.
The selected series will be dropped in front of the series where you release left mouse button.

E.g. Series-5 dragged preceeding Series-2:






Copy / Paste / Delete series

Click with right mouse buttn into a series.
A context menu opens up:






Data symbols

Data symbols in the different groups may have individual style:



Select one or multiple series.
All modifications are aplied to all selected series.
If no series are selected, all are modified.





Statistics

Beneath the date itself, DotChart may indicate addtionally - or only - statistical indicators.

In the toolbox use the Statistics options to adopt the chart:


Show either indiviual or in any combination:
The width of the statistic elements follows the width of a data series and may be influenced by adjusting the PPL and Size fields.

As with any other statistical analysis, conclusions should only be drawn from data series with large enough sample size.

Parameters are applied to the selected groups.
Graphical settings may differ from the settings for respective series' symbols.
If no series are selected, modifications are applied to all series.






Group tests

To perform group tests, select 2 or more individual data series.

Click with right-mouse button into any of the selecdted series.
From context menu select:
to test, whether the selected series share the same gaussian distribution.




A input dialog opens up.
Here, you may define the text dsplayed on top of the test indicator in the graph.
By default, the p-value in scientific format is used:



Change the text any way you prefer and click OK button.
Click Cancel button to abandon the test.


Edit "text" of a test

Click the bracket, close to the first series of a group test with right mouse button:


From context menu select Edit to change the text displayed.

Select Remove to remove the selected "test" from the chart.


Adjust bracket

You may adjust the horizontal connector of a test's bracket:
Click the bracket, close to the first series of a group test.
Keep left mouse button clicked and move the connector - and the text - up/down.





Forest plot

DotChart may be used to generate forest plots.

Forest plots are used to view e.g. results from Cox-regressions - as with SUMO's cox regression tool.



To view hazard ratio(confidence interval/p-vlaue check View data field.

Click with right mouse button into a chart area.
From context menu you may change Text and Font of the respective item.

Adjust the distance between the data field (top of graph) or Series names (bottom of graph) by defining tab distances.
(Dotchart | Main menu | Preferences | Tabstops) For the example picture Top tabs area adjusted to "10,50,150" pixel,
Bottom tabs to "120,50,20" pixel.

Tabs in series names are entered as "\t" (e.g. "Smith et al. 1991\t24").

The gap after after trial-3 ("miller et al.) is generated by:

Copy / Paste forest plot data

You may import data as multiline tab delimited data from clipboard.

Prepare a muliline text:
Copy the text to clipboard and paste it into DotChart:
(Dotchart | Main menu | Edit | Forest plot | Paste data).
