The Label form ()
draws a text label by each point position.
Example Label plot
Label form configuration panel
The configuration options are:
Text
A column or expression from the table supplying the text to
write on the plot. Any data type (string or numeric) is permitted.
Text Syntax
How to turn the text into characters on the screen.
Plain and Antialias both take the
text at face value, but Antialias smooths the characters.
Antialiased text usually looks nicer, but can be perceptibly slower to plot.
At time of writing, on MacOS antialiased text seems to be required to
stop the writing coming out upside-down for non-horizontal text.
LaTeX interprets the text as LaTeX source code
and typesets it accordingly.
Font Size
Size of the font in points.
Font Style
Style of the font - standard, serif or monospaced.
Font Weight
Whether the font is plain, bold or italic.
Anchor
The position of the text relative to the data position.
X Offset
Y Offset
Supplies pixel offsets for the label positioning.
This allows fine adjustment of where the labels will appear.
Each value is in pixels, and may be positive or negative.
Spacing Threshold
Crowding Limit
These two options control how closely spaced labels can be.
Labels which are too closely crowded together will simply not be shown,
since overplotting many labels together ends up with them being illegible.
The Spacing Threshold slider controls the smallest
area that a group of labels can have to themselves - if there are too
many in the same area, none will be drawn. Sliding it left allows more
crowding and right allows less. The Crowding Limit
controls the largest number of labels that can be in a group.
Setting it to 2 for instance is useful if you want to see pairs of
labels, even if the pair is close.
