Hi Brian, could you please show me how can I reproduce the problem ? Hi Pep, Sorry to have taken so long to reply. I dont have a clean and simple chart to give you to demo the problem, but am I being naieve? Surely OffsetList is never Free'd anywhere? I entered OffsetList.Free in Destroy and the pr...

Hi, I have added PDF export to my list of exported chart format and notice that there seems to be a memory leak with OffsetList - see below. Is it the way I'm using it or do I see OffsetList is not being freed, only cleared in Destroy? Regards, Brian constructor TTeePDFPage.Create; begin inherited C...

Sorry, I meant "It would be great if DrawAllPoints FALSE looked at the data...."

Narcis, Thanks it was me. I had DrawAllPoints set false becuase this was a good speed increase at an earlier time. I think I will have to leave DrawAllPoints set true and live with the increased time. It would be great if DrawAllPoints true looked at the data and rendered the max (or min) of the dat...

THanks Narcis. This works but it has also shown that I must be supressing the few high values becuase I notice that your example shows single pixel lines where the values exist, even if I plot 1,000,000 points. I will go and examine my code!
Thanks
Brian

I've a need to show the user that there is a point on my line series that is very different from the rest, for example 100,000 points may be value=50 but point 1234 may be value=80. When the chart draws, it can hide this single event. How best can I make it visible?
Thanks
Brian

Sorry if this has been asked before but I have a need to ensure that when display a line chart of many similar points (eg 10,000 points of say value = 100) that a single different numeric event (say value = 0) is visible even when looking at the entire chart as well as when zoomed in. It seems to me...
