rticks

Set or query r-axis tick values

Syntax

rticks(ticks)

rt = rticks

rticks('auto')

rticks('manual')

m = rticks('mode')

___ = rticks(pax,___)

Description

rticks(ticks) sets the r-axis tick values, which are the locations along the r-axis where the tick marks and grid lines appear. Specify ticks as a vector of increasing values; for example, [0 2 4 6]. This command affects the current axes.

rt = rticks returns the current r-axis tick values as a vector.

rticks('auto') sets an automatic mode, enabling the axes to determine the r-axis tick values. Use this option if you change the tick values and then want to set them back to the default values.

rticks('manual') sets a manual mode, freezing the r-axis tick values at the current values. Use this option if you want to retain the current tick values when resizing the axes or adding new data to the axes.

m = rticks('mode') returns the current r-axis tick labels mode, which is either 'auto' or 'manual'. By default, the mode is automatic unless you specify tick values or change the mode to manual.

___ = rticks(pax,___) uses the axes object pax instead of the current axes. Specify pax as the first input argument for any of the previous syntaxes.

Examples

Specify r-Axis Tick Values and Labels

Create a polar plot. Display tick marks and grid lines along the r-axis at the values 0.1, 0.3, and 0.5. Then, specify a label for each tick mark.

theta = linspace(0,2*pi);
rho = theta/10;
polarplot(theta,rho)
rticks([0.1 0.25 0.5])
rticklabels({'r = .1','r = .3','r = .5'})

Specify Nonuniform r-Axis Tick Values

Display tick marks and grid lines along the r-axis at nonuniform values between 0 and 10. MATLAB® labels the tick marks with the numeric values.

theta = 0:0.01:2*pi;
rho = 10*sin(2*theta);
polarplot(theta,rho)
rticks([0 4 5 6 10])

Increment r-Axis Tick Values by 10

Display tick marks and grid lines along the r-axis at increments of 10, starting from 0 and ending at 50.

theta = 0:0.01:2*pi;
rho = 50*sin(2*theta);
polarplot(theta,rho)
rticks(0:10:50)

Set r-Axis Tick Values Back to Default Values

Create a polar plot and specify the r-axis tick values. Then, set the r-axis tick values back to the default values.

polarplot(1:10)
rticks([0 5 10])

rticks('auto')

Specify r-Axis Tick Values for Specific Polar Axes

Create polar axes and return the polar axes object pax. Ensure that rticks affects the polar axes you just created by passing pax as the first input argument to the function.

pax = polaraxes;
rticks(pax,[0 .5 1])

Remove r-Axis Tick Marks and Grid Lines

Remove the tick marks and grid lines along the r-axis by specifying the tick values as an empty array.

polarplot(1:100)
rticks([])

Input Arguments

ticks — Tick values

vector of increasing values

Tick values, specified as a vector of increasing values. If you do not want tick marks along the r-axis, specify an empty vector [].

Example: rticks([0 1 2 3 4])

Example: rticks(0:10:100)

Example: rticks([])

Note

To specify the tick labels, use the rticklabels function.

pax — Polar axes

polar axes | array of polar axes

Polar axes, or an array of polar axes. If you do not specify this argument, then rticks modifies the current axes (provided that the current axes is a polar axes object).

Output Arguments

rt — Current tick values

vector

Current tick values, returned as a vector.

m — Current mode

'auto' | 'manual'

Current mode, returned as one of these values:

• 'auto' — Axes automatically determines the r-axis tick values.

• 'manual' — Axes uses manually specified r-axis tick values.

More About

Tick Values

The tick values are the locations along the r-axis where the tick marks appear. The tick labels are the labels that you see next to each tick mark. Set the tick values using the rticks function. Set the corresponding tick labels using the rticklabels function.

Algorithms

The rticks function sets and queries several axes properties related to the r-axis tick values.

• RTick — Property that stores the r-axis tick values.

• RTickMode — Property that stores the r-axis tick value mode. When you set the r-axis tick values, this property changes to 'manual'.
