how to set y-axis if the value is less than 0 with one groups their value is greater than 10 in matlab

To set the y-axis in MATLAB when the values are less than 0 and there is a group with values greater than 10, you can use the ylim function to specify the range of the y-axis.

Here's an example:

main.m
x = 1:10; % x-values
y = [-5, 8, -3, 15, -1, 7, -2, 12, -4, 10]; % y-values

% Create a scatter plot
scatter(x, y)

% Set the y-axis limits to range from the minimum y-value to the maximum y-value,
% with additional padding to accommodate the group with values greater than 10
axis([min(x), max(x), min(y)-2, max(y)+2])

% Update the y-axis tick labels to include a label for values less than 0
yticks([min(y)-2, 0, max(y)+2])
yticklabels([min(y), 0, max(y)])

In this example, the axis function is used to set the x-axis limits to the minimum and maximum x-values, while also setting the y-axis limits to the minimum y-value minus 2 and the maximum y-value plus 2. This provides some padding above and below the data points. The yticks function is then used to specify the specific tick positions on the y-axis, and the yticklabels function is used to provide custom labels for those tick positions. This way, you can visualize the data points with values less than 0 and also account for the group with values greater than 10 on the y-axis.
