Scatterplot - Selection groups

To emhpasize certain sub-groups in your data set, you may visualize sub-groups defining specific:

symbol
size
brushcolor
border (=pen) color
border (=pen) width
for up tp 100 subgroups

Select data points for a group:

draw regions of interest (ROIs) with the mouse
search in datapoints, names or nummerical values.

Sub-group preferences are memorized.
Different sets may be saved for later reusal.

Select data points

Draw a selection area with left mouse button pressed on the scatterplot.

Select the ROI type first (Main menu | Preferences | Selection):

Rectangle:
Rhomboid, i.e. a selection box parallel to the main diagon of the graph:
Freehand:

All datapoints within the selected Region Of Interest (ROI) are listed in the Seesion log tabsheet.
Select Main menu | View | Selection list to view an additional table showing the selected datapoints' values:

Find datapoints

Select Main menu | Edit | Find

data points' names/comments:

data values
"\x>=xxx.xx" to search all objects where X-valiue is equal or larger xxxx.xx
"\x<=xxx.xx" to search all objects where X-valiue is equal or smaller xxxx.xx
"\y>=xxx.xx" to search all objects where Y-valiue is equal or larger xxxx.xx
"\y<=xxx.xx" to search all objects where Y-valiue is equal or smaller xxxx.xx
"\s>=xxx.xx" to search all objects where key column is equal or larger xxxx.xx
"\s<=xxx.xx" to search all objects where key column is equal or smaller xxxx.xx
"\c>=xxx.xx" to search all objects where key column is equal or larger xxxx.xx
"\c<=xxx.xx" to search all objects where key column is equal or smaller xxxx.xx
"\R<=xxx.xx" to search all objects where RATIO x/y<=xxx.xx
"\R>=xxx.xx" to search all objects where RATIO x/y>=xxx.xx
"\LR<=xxx.xx" to search all objects where RATIO log2(x/y)<=xxx.xx
"\LR>=xxx.xx" to search all objects where RATIO log2(x/y)>=xxx.xx
Search modifiers:
By default a "new" search is performed. I.e. previous selection is cleared and newly found objects get selected.
"\or" Preceed you search list with "or" to keep previous selction and newly found objects to your new seach result selection.
"\and" will only select objects which are members of your previous selection and the new search.

A list of matching data points is shown in the Session log tab-sheet.

Define groups

Click the G+ toolbar button to define the selected data points as a group.

To remove all groups, click the G-X toolbar button.

Join any two selection groups: Main menu | Preferences | Selection | Join selection groups.

Customize the group's preferences

Click the GP toolbar button.

A parameter dialog opens up:

To select a group for customizing, just click one member datapoint in the scatterplot or Select group edit/drop-down field in the dialog.

Adjust the values accordingly:

Selection group	Select the selection group you wish to change, or more easily just click with left mouse button into the group in scatterplot view. The group's parameters are shown in the dialog.
Symbol	Select a symbol from the drop-down list: Box,circle,triangle,diamond, ... female-/male-symbol - obvious 3D-Sphere: Plot a sphere with color gradient, bright spot "looking" into a certain direction: define: 3D-sphere;backgroundcolor;centrecolor;xdirection;ydirection Color: any color (red,green,blue,...,rgb(rrr,ggg,bbb)) To pick any color use *SUMO's color picker: SUMO \| Main menu \| Utilities \| Color picker*. Select a color and click the >C -button to copy the color value into clipboard. Direction: 0..100, with 0=left/top, 100=right/bottom e.g. "3d-sphere;navy;red;66;66; => e.g. "3d-sphere;rgb(192,255,192);red;33;66; => Select "none" to hide the group.
Symbol size	Size of the symbol in pixel Select "none" to keep the dataponts' size in case the "size"-series was specified.
Pen color	Select a color to for smybol's border. Select any of the preset colors. Define a custom color with "rgb(rrr,ggg,bbb)" Click the ... -button to open a color selection dialog.
Penwidth	Width of the symbol's border in pixel.
Brush bolor	Color to fill the symbol. Same option as above for pen color Select "clNone" to keeep the data points' color in case the "color"-series was specified.
Group name	Name of the group, showing up in the group-legend panel.
Connector.	Connect all group members by lines to their centre of mass:

Present group settings are saved when closing Scatterplot viewer.

You may also save a specific set (e.g. project specific settings) separately:
Main Menu | Preferences | Selection | Save group settings.

Sample scatterplot:

Color and size of the symbols are used to visualize two additonal parameters
Three selection groups visulaized with:
- different symbols
- pen color
- pen width

Variable symbols's size/color were kept in the selection groups, by defining both size/color as "none" for all the selection groups.

Same data set as above, but:
