        xticks The function is to set or query x Axis scale value .

grammar

xticks(ticks)
xt = xticks
xticks('auto')
xticks('manual')
m = xticks('mode')
___ = xticks(ax,___)

explain

        xticks(ticks) Set up x Axis scale value , These values are x The position of the scale mark displayed on the axis . Appoint ticks Is the increment vector ; for example [0 2 4 6]. This command works on the current coordinate area .
        xt = xticks Returns the current as a vector x Axis scale value .
        xticks('auto') Set auto mode , Make the coordinate area determined x Axis scale value . If you change the scale value , Then I want to set them back to the default value , You can use this option .
        xticks('manual') Set manual mode , take x The axis scale value is frozen at the current value . If you want to keep the current scale value while resizing the coordinate area or adding new data to the coordinate area , You can use this option .
        m = xticks('mode') Returns the current x Axis scale value mode ：'auto' or 'manual'. By default , The mode is automatic , Unless you specify a scale value or change the mode to manual .
        ___ = xticks(ax,___) Use ax Specified coordinate area , Instead of using the current coordinate area . Appoint ax As the first input parameter of any of the above Syntax .

Example

Appoint x Axis scale values and labels

         Create a line diagram . At value 0、5 and 10 Show  x  The scale mark of the shaft . Then assign a label to each tick mark .

x = linspace(0,10);
y = x.^2;
plot(x,y)
xticks([0 5 10])
xticklabels({'x = 0','x = 5','x = 10'})

Specify non-uniform  x  Axis scale value

         Along the x Axis in between -5 and 5 The non-uniform values between show the tick marks .MATLAB Mark the scale mark with numerical value .

x = linspace(-5,5);
y = x.^2;
plot(x,y)
xticks([-5 -2.5 -1 0 1 2.5 5])

With 10 Increment for increment  x  Axis scale value

         Along the x Axis to 10 Show tick marks for increments , from 0 Start , stay 50 end .

x = linspace(0,50);
y = sin(x/2);
plot(x,y)
xticks(0:10:50)

With Pi Increment for increment  x  Axis scale value

         Create a line diagram . take x The axis range is specified as 0 To 6π. then , With π Display for increment x The scale mark of the shaft .

x = linspace(0,6*pi);
y = sin(x);
plot(x,y)
xlim([0 6*pi])
xticks(0:pi:6*pi)

        MATLAB Mark the scale mark with numerical value . Change the label to display by specifying text for each label π Symbol .

xticklabels({'0','\pi','2\pi','3\pi','4\pi','5\pi','6\pi'})

Change... With duration  x  Axis scale value .

         establish  x  The axis is a graph of duration values . then , Change the duration value of the tick mark .

t = minutes(0:.5:3);
y = rand(1,7);
plot(t,y)

ticks = minutes(0:.25:3);
xticks(ticks)

take  x  The axis scale value is set back to the default value

         Create a needle chart and specify  x  Axis scale value . then , take  x  The axis scale value is set back to the default value .

stem(1:10)
xticks([0 4 6 10])

xticks('auto')

Specify... For a specific coordinate area  x  Axis scale value

         from R2019b Start , have access to tiledlayout and nexttile Function to display block diagram . call tiledlayout Function to create a 2×1 Block diagram layout . call nexttile Function to create a coordinate area object ax1 and ax2. Draw random data into each coordinate area . And then by putting ax2 As xticks The first input parameter of the function is passed , Set the... In the figure below x Axis scale value .

tiledlayout(2,1)
ax1 = nexttile;
plot(rand(3))
ax2 = nexttile;
plot(rand(3))
xticks(ax2,[1 2 3])

Delete  x  Axis scale mark

         Delete the edge by specifying the scale value as an empty array x The scale mark of the shaft .

x = linspace(0,10);
y = sin(x);
plot(x,y)
