OnTopLeftChanged in TChartGrid

Hi,

is there any reason, why the OnTopLeftChanged event is not contained in the TChartGrid properties?

Thanks, Messie

Re: New forum

Hi, is it really necessary to skip too long words in the search with the new forum? The following words in your search query were ignored because they are too common words: ontopleftchanged . You must specify at least one word to search for. Each word must consist of at least 3 characters and must n...

Re: Wrong Data shown in TChartEditor using DateTime Values

Yes, you're right. I thought that this was the correct position to set. So where can I set the format string for the DateTime X Axis?

Thanks, Ulfert

Wrong Data shown in TChartEditor using DateTime Values

Hi, If I add DateTime Values to the bottom axis an open a Charteditor at runtime, the x values are shown correctly but the y values show the DatTime FormatString ('hh:mm') instead of the correct data. y data points are simple integer values. See attachment. Any suggestion about that behavior? TeeCha...

Hi Pep. meanwhile I found out that there is no real difference between the runtime and the designtime chart but the size. So I enlarged the runtime chart to width>5000 Pixel and the printing is fine now. It looks like the chart resolution is not good. If I display the form with runtime chart, the st...

Hi, any suggestions what might be the reason? I loaded the data into another chart which was prepared at designtime and the exported metafile looks quite better. I can'T find out why the chart created at runtime is so different. Is there any possibility to export all the chart settings? Thanks, Messie

meanwhile I extracted and uploaded parts of the function. Maybe this way you can see which settings are wrong.

Hi,

It is a bit tricky to post a simple example but I sent the metafile. The chart is designed at runtime as well as the parent form.

Thera are data points each 10°C where the y-axis data is raising smoothly

Chart printing: stepped appearence

Hi,

when I print my chart, I see steps which do not refer to the real data.
To check if it is a printer settings problem, I saved the metafile (printed with stretchdraw). The metafile shows the same problem.
So how do I get to a proper printed chart?

Thanks, Messie

Probier mal, ob Du das CursorTool mit Pfeiltasten bewegen kannst. Wenn Du mit der Maus arbeitest, wird das OnMouseOver mit einigen hundert Hz gefeuert. Dazu wird jedesmal der Wert rausgesucht -> macht den Rechner langsam. Wenn Du das mit Tasten machst, kommt da höchstens Deine Wiederholrate raus. Gr...

DateTime hours "overflow" after 24h

Hi, I need to display a DateTime axis where the labes show hours and minutes. I found no way to display e.g. 26h as 26:00. Is there any workaround for that? I would accept to get 1d 2h 0m, but the calculation always starts at the 30. (december 1899) so I get 31:02:00. I already have caught the data ...

assigning series to customaxis at runtime
