具有实线&灰色 [英] Minor grid with solid lines & grey-color

问题描述

我使用以下方式在我的情节中显示次要网格：

  grid（gca，'minor'） 
 set（gca，'MinorGridLineStyle'，' - '）
  

将网格线的颜色更改为漂亮的灰度。我找不到任何选项'网格颜色'在matlab ...你知道任何或任何解决方法？
我发现这个：

解决方案

设置轴，并删除其子项。

 ％＃像往常一样创建一个图（x轴在对数范围）
 semilogx（logspace（0,5,100），cumsum（rand（100,1）-0.5））
 xlabel （'x'），ylabel（'y'），title（'text'）
 legend（'plot'）
 
％＃捕获当前图形和轴的句柄
 hFig = gcf; 
 hAx1 = gca; 
 
％＃创建第二个透明轴，作为第一个透明轴的副本
 hAx2 = copyobj（hAx1，hFig）; 
 delete（get（hAx2，'Children'））
 set（hAx2，'Color'，'none'，'Box'，'on'，... 
'XGrid' 'off'，'YGrid'，'off'）
 
％＃显示第一轴的网格线，根据需要设置样式，
％＃但隐藏其标记和轴标签
 set（hAx1，'XColor'，[0.9 0.9 0.9]，'YColor'，[0.9 0.9 0.9]，... 
'XMinorGrid'，'on'，'YMinorGrid'，'on' 'MinorGridLineStyle'，' - '，... 
'XTickLabel'，[]，'YTickLabel'，[]）; 
 xlabel（hAx1，''），ylabel（hAx1，''），title（hAx1，''）
 
％＃链接两个轴， 
 linkaxes（[hAx1 hAx2]，'xy'）; 
 
％＃注意，`gca == hAx1`从这一点开始... 
％＃如果要更改轴标签，请明确使用hAx2作为参数。 
  

您应该使用此代码在示例中获得正确的图。然而，我认为您选择的 x 变量值可能在当前图形大小过于接近，以显示所有的垂直线（只是最大化图，看看我的意思）。 。

为了更好地了解每个轴包含什么，这里是一个分割视图，其左侧的图只包含由 hAx1 ，而右侧的图只包含 hAx2 组件。

I'm using the following to display the minor grid in my plot:

grid(gca,'minor') 
set(gca,'MinorGridLineStyle','-')

but I'd like to change the color of the grid lines to a nice greyscale. I can't find any option 'grid color' in matlab... Do you know any or any workaround? I found this: http://www.mathworks.com/matlabcentral/fileexchange/9815-gridcolor but as I read of the comments, it doesn't work very well and further it only changes gridcolor, not the color of the minor grid... Thanks!

EDIT: Problem with semilogx as posting here now:

x = [1e-9 1e-8 1e-7 1e-6 1e-5 1e-4 1e-3 1e-2]';
y1 = linspace(20, 90, 8);
y2 = y1.^2;
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]:
p1 = semilogx(x,y1,'x--r',x,y2,'*-b');

ax1 = gca;
set(ax1, 'Position',[0.13 0.18 0.75 0.75]);

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'),...
    'XScale', 'log');

%# 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',[],'XScale', 'log');


%# link the two axes to share the same limits on pan/zoom
linkaxes([ax1 ax2],'xy');

Displaying like this:

EDIT2: A problem occurs when adding a second y-axes as in the following picture, look at the ticks of the right y-axes:

this will be discussed here to have a better overview! Matlab: Problem with ticks when setting minor grid style and two y-axis

解决方案

Set the 'XColor','YColor' axes properties. Note that these properties determine the color of the axis lines, tick marks, tick mark labels, and the axis grid lines, so AFAIK you can't assign those different colors than that of the entire axis..

Example:

plot(rand(10,1))
set(gca, 'XMinorGrid','on', 'YMinorGrid','on', 'XColor','r', 'YColor','g')

---

EDIT1:

You can always create a second transparent axis with the desired grid colors, but with no ticks or labels, stacked on top of the current axis. Here is an example:

%# create plot as usual
plot(rand(10,1))
hAx1 = gca;

%# create a second axis, same position/extents, no tick or labels, colored grid-lines
hAx2 = axes('Position',get(hAx1,'Position'), ...
    'Color','none', 'TickLength',[1e-100 1e-100], ...
    'XMinorGrid','on', 'YMinorGrid','on', ...
    'Box','off', 'XColor','g', 'YColor','r', ...
    'XTickLabel',[], 'YTickLabel',[], ...
    'XTick',get(hAx1,'XTick'), 'YTick',get(hAx1,'YTick'), ...
    'XLim',get(hAx1,'XLim'), 'YLim',get(hAx1,'YLim'));

%# position it on top
%#uistack(hAx2,'top')

%# redraw the enclosing box in the original axis colors
x = get(hAx1,'XLim');
y = get(hAx1,'YLim');
line([x([1 2]) nan x([2 1])],[y([1 1]) nan y([2 2])],'Color',get(hAx1,'XColor'))
line([x([1 1]) nan x([2 2])],[y([1 2]) nan y([2 1])],'Color',get(hAx1,'YColor'))

The only problem is that the grid lines are drawn on top of your plot, which might get in the way if the grid-lines are thick :)

EDIT2:

Seems like @yoda had a similar idea to the above. Here is a slightly improved version inspired by his solution:

%# create plot as usual
plot(11:20, rand(10,1)*5)
hAx1 = gca;   %# get a handle to first axis

%# create a second transparent axis, same position/extents, same ticks and labels
hAx2 = axes('Position',get(hAx1,'Position'), ...
    'Color','none', 'Box','on', ...
    'XTickLabel',get(hAx1,'XTickLabel'), 'YTickLabel',get(hAx1,'YTickLabel'), ...
    'XTick',get(hAx1,'XTick'), 'YTick',get(hAx1,'YTick'), ...
    'XLim',get(hAx1,'XLim'), 'YLim',get(hAx1,'YLim'));

%# show grid-lines of first axis, give them desired color, but hide text labels
set(hAx1, 'XColor','g', 'YColor','r', ...
    'XMinorGrid','on', 'YMinorGrid','on', ...
    'XTickLabel',[], 'YTickLabel',[]);

%# link the two axes to share the same limits on pan/zoom
linkaxes([hAx1 hAx2],'xy');

%# lets create a legend, and some titles
legend(hAx1, 'text')
title('title'), xlabel('x'), ylabel('y')

---

EDIT3 (take 2):

Here is the same example but with a log-scale x-axis. Note how instead of creating a second axis and manually setting its properties to match the first, I simply copyobj the axis, and delete its children.

%# create a plot as usual (x-axis is in the log-scale)
semilogx(logspace(0,5,100), cumsum(rand(100,1)-0.5))
xlabel('x'), ylabel('y'), title('text')
legend('plot')

%# capture handle to current figure and axis
hFig = gcf;
hAx1 = gca;

%# create a second transparent axis, as a copy of the first
hAx2 = copyobj(hAx1,hFig);
delete( get(hAx2,'Children') )
set(hAx2, 'Color','none', 'Box','on', ...
    'XGrid','off', 'YGrid','off')

%# show grid-lines of first axis, style them as desired,
%# but hide its tick marks and axis labels
set(hAx1, 'XColor',[0.9 0.9 0.9], 'YColor',[0.9 0.9 0.9], ...
    'XMinorGrid','on', 'YMinorGrid','on', 'MinorGridLineStyle','-', ...
    'XTickLabel',[], 'YTickLabel',[]);
xlabel(hAx1, ''), ylabel(hAx1, ''), title(hAx1, '')

%# link the two axes to share the same limits on pan/zoom
linkaxes([hAx1 hAx2], 'xy');

%# Note that `gca==hAx1` from this point on...
%# If you want to change the axis labels, explicitly use hAx2 as parameter.

You should get the correct plot in your example with this code. However I think the x variable values you choose might be too close in the current figure size to show all the vertical lines (simply maximize the figure to see what I mean)...

To get a better idea of what each axis contains, here is a divided view where the plot on the left contains only the graphics rendered by hAx1, while the plot on right contains only the hAx2 components. Those two views are basically overlayed on top of each other in the final figure shown before.
