thetalim

Set or query theta-axis limits for polar axes

Syntax

thetalim(limits)
thetalim('auto')
thetalim('manual')
tl = thetalim
m = thetalim('mode')
___ = thetalim(pax,___)

Description

example

thetalim(limits) specifies the theta-axis limits for the current polar axes. Specify limits as a two-element vector of the form [thetamin thetamax], where thetamax is a numeric value greater than thetamin.

example

thetalim('auto') lets MATLAB® choose the theta-axis limits. This command sets the ThetaLimMode property for the polar axes object to 'auto'.

thetalim('manual') prevents the limits from changing automatically. This command sets the ThetaLimMode property for the polar axes object to 'manual'.

tl = thetalim returns a two-element vector containing the limits for the current polar axes.

m = thetalim('mode') returns the current value of the limits mode, which is either 'auto' or 'manual'. By default, the mode is automatic unless you specify limits or set the mode to manual.

example

___ = thetalim(pax,___) uses the polar axes object specified by pax instead of the current polar axes. Specify pax as the first input argument. Include additional input or output arguments only if the original syntax supported them.

Examples

collapse all

Create a polar plot and change the theta-axis limits.

theta = linspace(0,pi);
rho = theta/10;
polarplot(theta,rho)
thetalim([0 180])

Set the limits back to the original values.

thetalim('auto')

Set the limits for a specific polar axes by specifying the polar axes object as the first input to thetalim. Otherwise, thetalim sets the limits for the current axes.

pax = polaraxes;
thetalim(pax,[0 180])

Input Arguments

collapse all

Minimum and maximum limits, specified as a two-element vector of the form [thetamin thetamax]. When you specify the limits, the ThetaLim property for the polar axes object updates to the specified values.

Example: [0 1]

Polar axes object. If you do not specify a polar axes object, then thetalim sets the limits for the current polar axes.

Output Arguments

collapse all

Current limits, returned as a two-element vector of the form [thetamin thetamax]. Querying the limits returns the value of the ThetaLim property for the polar axes object.

Current limits mode, returned as one of these values:

  • 'auto' — Limits automatically update to reflect changes in the data.

  • 'manual' — Limits do not automatically update.

Querying the theta-axis limits mode returns the value of the ThetaLimMode property for the polar axes object.
