Add a TChart and a Series and open the series 'Data Source' tab. There should most likely be a "Random" entry visible at the top of the tab (without any label but be best guess thats the 'data source')

Now just drop that list down and accidentally select 'Excel' than switch back to 'Random' and close the tab.
This will add a TTeeExcelSource entry to your forms interface even though you never really needed on.

Best of all try to open that tab again and switch back and force between 'Random' and 'Excel' and you will get another instance of TTeeExcelSource ... of course you can repeat that procedure to get an unlimited number of TTeeExcelSource in your form.

...and as this gets boring the same happens with TTeeXMLSource and propably any other source you select there...

PS.: the only way to get rid of that stuff, is to delete the referencies in the interface section open the dfms source and delete all references there

PS.PS.: the "Random" setting isnt storing changes in the dfm - so chaning the number of samples from 25 to 10 and reopening the from resets that value back to 25...

Hello Whookie,

We added a feature request in the VCL TeeChart bugzilla tracker to consider add a hint before add the TTeeExcelSource to prevent possible incorrect adding. The bug number is ID863. Feel Free to add your email account to the ticket so you can be automatically notified when and update arrives.

Thanks in advance,

There is one thing which might have slipped through:

PS.PS.: The "Random" setting isn't stored in the .dfm - so changing the number of samples from 25 to 10 and reopening the from resets that value back to 25...

Hello Whookie,

I apologise with you, I forgot add it to Bug Tracker. We've already added the problem in VCL TeeChart bugzilla tracker to fix it to upcoming versions of TeeChartVCL with number ID868.

Thanks,
