question on series

[User (Legacy)]

greetings... 

I have a trial version (with intent to purchase) of ChartFX98, running 

under BCB 5.0. 

two questions: 

1) how can I have a chart display zero seires upon startup? currently, 

I'm making the first series invisible, and that works ok, but if the 

user chooses the properties box, Series 1 still shows. 

2) when I place two series with different x-axis limits, prior series 

that do not extend to the max of other series, have data in them, set to 

0. For the application I am writing, this makes the graphs look awkward, 

and could lead to confusion for the users. How can I prevent this from 

happening? what I'd like to see is that if series 1 has min max x-axis 

values of 200 and 400, and series 2 has min max x-axis values of 300 and 

700,  I would want two series to show up, with the first series simply 

not having any plot points over 400 for the x-axis. 

thanks
