The Text Label form ()
draws a text label by each point position.
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
Whether to use plain text or LaTeX rules to make sense of the text
value.
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.
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.
