rticks

Set or query r-axis tick values

Syntax

rticks(ticks)
rt = rticks
rticks('auto')
rticks('manual')
m = rticks('mode')
___ = rticks(pax,___)

Description

example

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.

example

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.

example

___ = 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

collapse all

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'})

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])

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)

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')

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 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

collapse all

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.

One or more polar axes, specified as a single object or a vector of objects. If you do not specify the polar axes, then rticks uses the current axes.

Output Arguments

collapse all

Current tick values, returned as a vector.

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'.
