MATLAB: Do I receive an assertion when I specify the property “xdatasource” in PLOT

assertionMATLABplotr14xdatasourceydatasourcezdatasource

The code
z = 1:10;
plot(1:10,'xdatasource',z)
gives the following error:
 Caught unexpected exception of unknown type.

Best Answer

This bug has been fixed in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:
There is a bug in MATLAB 7.0 (R14) in the way that the "xdatasource", "ydatasource" and "zdatasource" properties of lineseries objects are handled when the value for the property is not a string or a variable of type char.
To work around this issue, set these properties with a string as in the following code:
z = 1:10;
plot(1:10,'xdatasource','z')
