在MATLAB中绘制后的轴恢复

Question

绘制了文本文件中多种方法的输出后，轴的右上方和右上方均未显示。我需要拥有它们并像当前轴一样将它们加粗。

绘制的数据来自已存储每种方法的数据的文件。每个数据文件都是一个256x2文件，其中包含[0,1]之间的值。第一列是精度，第二列是召回率。

figure
hold on
for m = 1:length(methods)
  prFileName = strcat(readpath,dataset, '_', methods{m}, '_PRCurve.txt');
  R = load(prFileName);
  precision = R(:, 1);
  recall = R(:, 2);
  plot(recall, precision,'color',methods_colors(m,:),'linewidth',2);    
end
axis([0 1 0 1]);
hold off
grid on;
legend('methode one','method two')
xlabel('Recall','fontsize',12);
ylabel('Precision','fontsize',12);
set(gcf,'color','w');  %Background color
ax = gca;  % current axes
ax.GridLineStyle='-';
ax.GridAlpha=0.7;
ax.XAxis.LineWidth=4;
ax.YAxis.LineWidth=4;
Grid.LineWidth = 3;
set(gca,'FontName','Arial','FontWeight','bold');

我的输出：

Answer 1

box on将打开图形区域周围的框的显示。我相信这就是您要的。

您可能需要使用set(ax,'LineWidth',4)而不是ax.XAxis.LineWidth=4和ax.YAxis.LineWidth=4，我不确定是否有区别。
