9	9	You can also choose how numbers appearing in text are displayed (as rational fractions, reals or integers) by setting the [_field_](#command-field) of the variable, and also configure how the tuples for variables like points, vectors, and vectorfields are [displayed in text](#command-vectorform).

	11	+All commands follow the same syntax `\commandName{<varnameList>}{<value>}` with possibly an optional argument before the list of variable names, e.g. `\color[<transparency>]{<varnameList>}{<colorName>}`. The argument `<varnameList>` is a comma separated list of names of variables to which the command should be applied.

18	21	For `labeltext`, you can use standard text, LaTeX-commands, and math mode, as well as values of variables with the same syntax `\var{n}` as in texts. However, not all types of variables are supported in labels, but only those that provide a number value or function term. This includes coordinates of points to which you refer as `\var{p}[x]` and `\var{p}[y}`, as you would do in text.

94		-The [sequences](JSX-Visualization-Variables.md#15-sequences) in visualizations consist of points and lines. For changing the styling of its points use the `\style`-command like `\style{varname}{points:{styling-options}}` where `varname` is the name of the sequence-variable, and `styling-options` are styling options as described above for points.

	109	+The command `\sliderPositioning{<varnames>}{<value>}` allows to change that behaviour for the mentioned slider.
101	110	Currently, you can only change the width, by using as value e.g. `width:0.8`. Here, the number determines the width relative to the canvas width.
102	111	Default value is `0.4`.

104	113	# Enable traces for objects
105	114	You can make the objects leave temporary traces when they are moved by user interaction.
106		-The command for enabling this is `\trace[duration]{varname}{styling-options}` where `varname` is the name of the variable, and `styling-options` are styling options as described for the [command `\styling`](#further-stylings).
	115	+The command for enabling this is `\trace[duration]{<varnames>}{<styling-options>}` where `<varnames>` is the list of names of the variables, and `<styling-options>` are styling options as described for the [command `\styling`](#further-stylings).
107	116	The default styling for the trace is the same as for the object itself, so you only have to provide those attributes that should be different.
108	117	With the optional argument `duration`, you can provide a time (in milliseconds) for how long a part of the trace remains on canvas. Default is 300 (ms).
109	118	A special case occurs, if you set `duration` to `0`. In this case, all parts of the trace will remain visible until the user releases the mouse button.

113		-If you need to change label, color, styles etc. for several objects in the same way, instead of just giving one variable name as the first parameter, you can also give a comma separated list of variable names, e.g. if the three points `p1`, `p2` and `p3`should appear in red, you can simply use `\color{p1,p2,p3}{red}`.
