如何从绘图处理程序进行绘图? [英] How can I plot from a plot handler?

问题描述

我有情节的处理者或图形的处理者 示例:

I have the handler of the plot, or handle of the figure Example:

h = plot([1:0.2:10])
xx=get(h)
xx = 

           DisplayName: ''
            Annotation: [1x1 handle]
                 Color: [0 0 1]
             LineStyle: '-'
             LineWidth: 0.5000
                Marker: 'none'
            MarkerSize: 6
       MarkerEdgeColor: 'auto'
       MarkerFaceColor: 'none'
                 XData: [1x46 double]
                 YData: [1x46 double]
                 ZData: [1x0 double]
          BeingDeleted: 'off'
         ButtonDownFcn: []
              Children: [0x1 double]
              Clipping: 'on'
             CreateFcn: []
             DeleteFcn: []
            BusyAction: 'queue'
      HandleVisibility: 'on'
               HitTest: 'on'
         Interruptible: 'on'
              Selected: 'off'
    SelectionHighlight: 'on'
                   Tag: ''
                  Type: 'line'
         UIContextMenu: []
              UserData: []
               Visible: 'on'
                Parent: 173.0107
             XDataMode: 'auto'
           XDataSource: ''
           YDataSource: ''
           ZDataSource: ''

此处理程序包含所有绘图信息，如何再次绘图?这是plot的一个简单示例，但应该也可以与slice一起使用.

This handler contains all the plot information, how can I plot out again? This is a simple example with plot but it is supposed to work with slice as well.

推荐答案

如果我正确理解了您的问题，则希望使用结构xx再现图. 提供的答案cc​​ook正确，但是这是实现所需目标的较短方法:

If I understand your question correctly, you want to reproduce a plot using the struct xx. The answer ccook provided is on the right track, but here's a shorter way to achieve what you want:

figure
h2 = plot(0);
ro_props = [fieldnames(rmfield(xx, fieldnames(set(h2)))); 'Parent'];
xx = rmfield(xx, ro_props);
set(h2, xx)

最后一个set命令使用结构xx来设置所有值并复制您的绘图.请注意，在调用set之前，已将ro_props的只读属性从xx中删除.

The last set command uses struct xx to set all the values and reproduce your plot. Note that the read-only properties ro_props are removed from xx before calling set.

修改后的答案可以根据此建议自动检测只读属性.

modified answer to automatically detect read-only properties according to this suggestion.
