Graphing Large Amounts of Data
TWIMC
I have a datalog which contains a large amount of info (+10000 data points). When I try and plot anything more than 1000 points in Excel 2007, the app starts to labour quite seriously and takes forever to fomat a simple thing like axis scale. I assume that this is because the new Excel has some pretty fancy formatting options and it also runs live previewing as formats are changed within dialogue boxes. Is there a way to just draw simple scatter plots without any of the processor consuming embelishments? I just need basic formatting functionality. Thanks |

Graphing Large Amounts of Data
I don't have any good news for you, hopefully someone else will.
The slowdown in charting in 2007 is a long time complaint of many users. I have had some clients go back to earlier versions of Excel because of it. I've seen it take as much as 10x longer to generate the same chart in 2007 than it did in 2003. Also, with the large number of data points you may have, keep in mind that the limit of data points in series in 2D chart is 32,000 (4,000 in a 3D chart) in Excel 2007. Also, I found early on that the data points counter didn't clear from chart to chart on a single sheet; it turned out to be a limit of data points charted on a single sheet. Not sure if that's been fixed or not yet. "BSc Chem Eng Rick" wrote: TWIMC I have a datalog which contains a large amount of info (+10000 data points).
