Invalid error message in PlotCurveItem

[Antony Lee]

Lines 314-318 of PlotCurveItem.py (inp branch, commit 312) are currently

            if len(self.xData) != len(self.yData)+1: ## allow difference of 1 for step mode plots
                raise Exception("len(X) must be len(Y)+1 since stepMode=True (got %s and %s)" % (str(x.shape), str(y.shape)))
        else:
            if self.xData.shape != self.yData.shape: ## allow difference of 1 for step mode plots
                raise Exception("X and Y arrays must be the same shape--got %s and %s." % (str(x.shape), str(y.shape)))

but x and y are not defined, thus raising another error. I assume it should read self.xData.shape and self.yData.shape (and the calls to str aren't needed either).

Thanks Antony!
