How can I link a plot to an array in a structure to use data brushing? Maybe a bug?

Hi,

i want to link data in plot to the data in an array which is contained in a structure to use data brushing. Consider the following simple example:

v.C=rand(100,3);
v.X=v.C(:,1);
v.Y=v.C(:,2);
v.Z=v.C(:,3);
C=v.C;
plot3(v.X,v.Y,v.Z,'XDataSource','v.X','YDataSource','v.Y','ZDataSource','v.Z');brush on; linkdata; openvar('v.X');

plot3(C(:,1),C(:,2),C(:,3),'XDataSource','C(:,1)','YDataSource','C(:,2)','ZDataSource','C(:,3)');brush on; linkdata; openvar('C'); openvar('C(:,1)');

plot3(v.C(:,1),v.C(:,2),v.C(:,3),'XDataSource','v.C(:,1)','YDataSource','v.C(:,2)','ZDataSource','v.C(:,3)');brush on; linkdata; openvar('v.C'); openvar('v.C(:,1)');

The first and second plot works. If I brush data in the plot, the same points get marked in the variable editor. If I change the variable in the editor the plot gets updated.

However, the third plot does not work. If brush the data in the plot, no data is marked in the variable editor. Nevertheless, changing the data in the variable editor results in an correct update of the plot.

Is there a solution to this problem. Maybe it has something to do with this comment from the Matlab help (<http://www.mathworks.de/de/help/matlab/ref/linkdata.html?searchHighlight=%27YDataSource%27>)

" Note: Although you can use data brushing on linked plots of complex data, your brush marks only appear in the plot you are brushing, not in other plots or in the Variables editor. This is because function calls, such as real(x) and imag(x), that you specify as data sources are not interpreted when brushing graphed data. "

I have exactly the same problem. I wonder of there is any solution. I have to say, that if structure is indexed (v.a(1).X for example)) the problem is the same.

But, since so long nobody answered, I am affraid it is a bug.

Looks like a bug to me, since it's behaving unexpectedly. Have you tried submitting this to the MathWorks bug report page?

While they get that looked into, you may have to just stick to your workaround solutions.

I have sent a bug report.

Workaround is ugly in my case. I have to name individually all my structure vector, and the structure vector has indefinite size.
