Matlab:设置小网格样式和两个 y 轴时出现刻度问题
在此线程中的社区的帮助下: 带有实线的小网格和grey-color
我让它将小网格线设置为纯色和彩色样式。但是当添加第二个 y 轴时,它只会弄乱右轴上的 y 刻度!这是示例代码:
x = linspace(0, 10, 11);
y1 = x.^3+1;
y2 = x+1;
y3 = y1./y2+5;
% plotte: http://www.mathworks.com/help/techdoc/ref/linespec.html
myfig = figure('Position', [500 500 445 356]); %[left, bottom, width, height]:
ax1 = axes('Position',[0.13 0.18 0.75 0.75]);
hold on
p1 = plot(x,y1,'x--r');
p2 = plot(x,y2,'*-b');
xlim([0 max(x)]);
ylim([0 max([max(y1) max(y2)])]);
col=.85*[1 1 1];
%# create a second transparent axis, same position/extents, same ticks and labels
ax2 = axes('Position',get(ax1,'Position'), ...
'Color','none', 'Box','on', ...
'XTickLabel',get(ax1,'XTickLabel'), 'YTickLabel',get(ax1,'YTickLabel'), ...
'XTick',get(ax1,'XTick'), 'YTick',get(ax1,'YTick'), ...
'XLim',get(ax1,'XLim'), 'YLim',get(ax1,'YLim'));
%# show grid-lines of first axis, give them desired color, but hide text labels
set(ax1, 'XColor',col, 'YColor',col, ...
'XMinorGrid','on', 'YMinorGrid','on', ...
'MinorGridLineStyle','-', ...
'XTickLabel',[], 'YTickLabel',[]);
%# link the two axes to share the same limits on pan/zoom
linkaxes([ax1 ax2],'xy');
ax3 = axes('Position',get(ax1,'Position'),...
'XAxisLocation','top',...
'YAxisLocation','right',...
'Color','none',...
'XTickLabel', [],...
'XColor','k','YColor','k');
%# link the two axes to share the same limits on pan/zoom
linkaxes([ax1 ax2 ax3], 'x');
ylabel(ax3, 'Speedup []');
ylim(ax3, [0 max(y3)]);
hold on
p3 = plot(x,y3,'s-.m','Parent',ax3);
hleg = legend([p1 p2 p3], {'CPU', 'GPU', 'Speedup'}, 'Location', 'NorthWest');
xlabel(ax2, 'N_{Funcs}');
ylabel(ax2, 't [s]');
set(hleg, 'FontAngle', 'italic')

with help of the community in this thread: Minor grid with solid lines & grey-color
I got it to work to set minor grid lines as solid and coloured style. But when adding a second y-axes it just messes up the y-ticks on the right axis! heres the example code:
x = linspace(0, 10, 11);
y1 = x.^3+1;
y2 = x+1;
y3 = y1./y2+5;
% plotte: http://www.mathworks.com/help/techdoc/ref/linespec.html
myfig = figure('Position', [500 500 445 356]); %[left, bottom, width, height]:
ax1 = axes('Position',[0.13 0.18 0.75 0.75]);
hold on
p1 = plot(x,y1,'x--r');
p2 = plot(x,y2,'*-b');
xlim([0 max(x)]);
ylim([0 max([max(y1) max(y2)])]);
col=.85*[1 1 1];
%# create a second transparent axis, same position/extents, same ticks and labels
ax2 = axes('Position',get(ax1,'Position'), ...
'Color','none', 'Box','on', ...
'XTickLabel',get(ax1,'XTickLabel'), 'YTickLabel',get(ax1,'YTickLabel'), ...
'XTick',get(ax1,'XTick'), 'YTick',get(ax1,'YTick'), ...
'XLim',get(ax1,'XLim'), 'YLim',get(ax1,'YLim'));
%# show grid-lines of first axis, give them desired color, but hide text labels
set(ax1, 'XColor',col, 'YColor',col, ...
'XMinorGrid','on', 'YMinorGrid','on', ...
'MinorGridLineStyle','-', ...
'XTickLabel',[], 'YTickLabel',[]);
%# link the two axes to share the same limits on pan/zoom
linkaxes([ax1 ax2],'xy');
ax3 = axes('Position',get(ax1,'Position'),...
'XAxisLocation','top',...
'YAxisLocation','right',...
'Color','none',...
'XTickLabel', [],...
'XColor','k','YColor','k');
%# link the two axes to share the same limits on pan/zoom
linkaxes([ax1 ax2 ax3], 'x');
ylabel(ax3, 'Speedup []');
ylim(ax3, [0 max(y3)]);
hold on
p3 = plot(x,y3,'s-.m','Parent',ax3);
hleg = legend([p1 p2 p3], {'CPU', 'GPU', 'Speedup'}, 'Location', 'NorthWest');
xlabel(ax2, 'N_{Funcs}');
ylabel(ax2, 't [s]');
set(hleg, 'FontAngle', 'italic')

它比您想象的更简单:当您创建第二个轴
ax2
时,将'Box'
属性设置为'off'
而不是“开”
。更重要的是,您可以简化该部分并将其创建为:
Its simpler than you think: when you create the second axis
ax2
, set the'Box'
property to'off'
instead of'on'
.Even more, you can simplify that part and create it as:
第二个 y 轴“混乱”,因为从
y3
自动生成的YTick
与y1< 的
YTick
不一致/code> 和y2
。如果此视图是最终视图(意味着您不必放大/缩小或移动绘图),您可以手动定义
ax3
的YTick
以匹配斧头1The 2nd y-axis is "messed up" because the automatically generated
YTick
fromy3
does not agree with theYTick
fromy1
andy2
.If this view is final (meaning you don't have to zoom in/zoom out or move the plot), you can manually define the
YTick
ofax3
to match those ofax1
