[求助] origin 3D画图求助 已有2人参与

这几天使用origin作图   做一个3d的 wire图  

z(x,y)  0 使用的数据是在一个400*200的矩阵中   数据太多   画出来的话使用了speed mode后调整成了  下图的样子   怎么把这个样子的图输出或者直接粘贴出来?   
或者怎么可以减少矩阵的维数?  使数据减少一些   

因为即使在origin中调整到了下图的样子   粘贴或者输出到word中就变成了密密麻麻的一堆线了

The display of data in a graph window is controlled by a feature referred to as Speed Mode. This feature can be found on the Size/Speed tab at the layer level of the Plot Details dialog box by selecting Format: Layer Properties. There are two separate controls, one for graphs plotting from worksheet and another for matrix:

    Worksheet data, maximum points per curve.
    Matrix data, maximum points per dimension.

When enabled (it is often enabled by default), you can use Speed Mode to affect the display (and redraw speed) of your graph by reducing the number of data points used to plot each dataset contained in the layer. Graph windows that contain large datasets will therefore redraw much quicker when using this feature. It is important to note, however, that these controls do not affect the image you will obtain when exporting your graph. A separate control has been added for this purpose and is most likely the reason why your graph does not look the same on screen as it does in your exported image.

Select Formatage Properties and then click on the Miscellaneous tab. The control is called If speed mode is enabled for display, apply to graphic export as well. If you want your graph to export using your current Speed Mode settings, enable this check box. If you want your graph to export using all your data, leave this check box unchecked.

或者怎么样可以把矩阵中的数据减少一些呢?   
定义矩阵的时候是通过公示计算的   比如: z=aj+bi    定义一个400*200的矩阵  如果在定义的时候缩小10倍定义成一个40*20的矩阵   每一列或者每一行的X Y值是可以扩大的    但是在使用set value定义矩阵中的数值的时候 使用的公示还是z=aj+bi
其中的  i  j  还是行数(1-20)和列数(1-400)   并不是每列所代表的X的值 比如10.25   20.51  30.76   等等   

这种情况应该怎么处理?   

急求帮助

难道要使用QQ 截图么。。。。。

另外  在开启了speed mode后  图片上会有字样   怎么在使用图片的时候去除这个字样?
