MATLAB: Plot: x axis and y axis values with commas as 1000 separators

MATLAB

This is a question about values of x axis and y axis in the plot.

First,

https://www.mathworks.com/matlabcentral/answers/466944-how-can-i-prevent-scientific-notation-on-my-axes-in-matlab-r2015b-and-later

tells how to disable scientific notations.

Then, the x axis and y axis will be like '1000000' that is harder to read. I want to have commas as 1000 separaters that is '1,000,000.' Please advise.

You can format the tick labels using the TickLabelFormat property of the axis. For example:

ax = axes('YScale','log');
plot(ax,1:10,logspace(3,6,10));
ax.YAxis.Exponent = 0;
ax.YAxis.TickLabelFormat = '%,.0f';

See here for details:

(edit) Taking a closer look at the answer you linked, what you need is the comma in the format.

Starting in MATLAB R2015b, you can use axis ruler properties to customize the appearance of an individual axis. Please refer to the following examples for how you can remove scientific notation from your axis labels, in a way which is respected by zoom and pan.

In MATLAB R2016b and later:

>> h = plot(1:1000000, 1:1000000)
>> ax = ancestor(h, 'axes')
>> ax.XAxis.Exponent = 0
>> xtickformat('%.0f')

Setting the "Exponent" property of an axis to 0 removes the exponential notation common to all tick values. For more information, refer to the following documentation page:

https://www.mathworks.com/help/releases/R2019a/matlab/ref/matlab.graphics.axis.decorator.numericruler-properties.html#bun6izd-1-Exponent

The functions "xtickformat", "ytickformat", and "ztickformat" can then be used to customize the format of your tick labels. In this example, the format is set to fixed-point notation with zero decimal places, which removes the scientific notation from the individual tick labels. The following documentation page describes how to call the "xtickformat" function, and the additional formatting options which are available:

https://www.mathworks.com/help/matlab/ref/xtickformat.html

In MATLAB R2015b and R2016a:

>> h = plot(1:1000000, 1:1000000)
>> ax = ancestor(h, 'axes')
>> ax.XAxis.Exponent = 0
>> ax.XAxis.TickLabelFormat = '%.0f'

In releases R2015b and R2016a, you can use the "TickLabelFormat" property of an axis to customize the format of your labels. For more information on this property, refer to the following documentation page:
