Swaping values and series in bar-chart

Yes! It work fine! But why can't I get this simple application to work even when compiling on a newly installed D7 on a new computer?

Did you test the .exe I posted?

Hi Normand,

This may be a problem we have found on some ocasions. You could try changing the following line:

Code: Select all

  for I := 1 to NbOldSeries do BarChart.RemoveSeries(BarChart.Series[0]);

for this one:

Code: Select all

  for I := 1 to NbOldSeries do BarChart.Series[0].Free;

Great! It works! I will make sure the RemoveSeries is never used unless I see a note that it had been fixed.

Thanks!

Hi Normand,

I wouldn't take that as a habbit as it doesn't happen on all ocasions. However, I'm glad to hear we finally found a solution for your problem.

I thought the two were functionnally equivalent, but you seems to suggest that they are not. Can you tell me the differences. Will using the .free method causes some memory leaks or some settings not to be set properly?

Hi Normand,

The RemoveSeries method deletes (but not destroys) the specified ASeries parameter from the Chart list of series.

Calling this method is exactly the same as doing:

ASeries.ParentChart := nil ;

The Free method frees the Serie of Class SeriesClass.
