Are you going to make sure TAChart can do the plot during design-time ?
I am working at it, there are issues with registration of the new TExpressionSeries from a separate package (it's not in trunk, yet).
But anyway: why is the designtime argument so important to you? ExpressionPanel cannot plot a function as simple as "sin(x)" at designtime because bcMath is not added to the Builtins of the parser. And if it were, other similarly simple functions such as "tan(x)" would not work because they are not registered. So, the designtime argument has only very limited weight. But of course, there is always the possibility that I am missing some features of the fpexprparser.
