在 MATLAB Online 中打开

% 生成随机数据

rng(42); % 设置随机种子以确保可重复性

n = 100; % 数据点数量

x = randn(n, 1); % 生成正态分布的x坐标

y = 2*x + randn(n, 1); % 生成与x相关的y坐标（带噪声）

% 创建散点图

figure; % 创建新图形窗口

scatter(x, y, 50, 'filled'); % 绘制散点图，点大小为50，填充点

% 添加标签和标题

xlabel('X 轴');

ylabel('Y 轴');

title('二维散点图示例');

grid on; % 显示网格

% 可选：添加趋势线

hold on; % 保持当前图形

p = polyfit(x, y, 1); % 一次多项式拟合

yfit = polyval(p, x); % 计算拟合值

plot(x, yfit, 'r-', 'LineWidth', 2); % 绘制趋势线

legend('数据点', '趋势线', 'Location', 'best'); % 添加图例

% 设置美观的字体和大小

set(gca, 'FontSize', 12);

set(gca, 'FontName', 'Arial');

% 可选：保存图片

saveas(gcf, 'scatter_plot.png');

Hello people from afar, for example, I created a two-dimensional scatter plot, when using the function of saving as as a suffix with .jpg/.png in the image window, I can only export the image with the name "untitled", if I change the file name and then click save, MATLAB will automatically crash and exit, although I can let him save as the name "untitled", and then exit MATLAB to modify the file name, but this is too troublesome...

If I could, I would like to send a screen recording video to show how this error occurred，what is your email?

What's your command to save the image under the name "untitled" ?

If you look at the crash log file, do you see a reference to graphics_context.dll in it? If so, try updating to release R2023a Update 6 or later to see if this is bug report 3084267.

If the crash log file doesn't include that term, or you're using Update 6 or later already, please send the crash log file to Technical Support.
