User (Legacy) Posted June 6, 2002 Report Share Posted June 6, 2002 Hello there, It seems this product is not really capable of performing Scroll or Realtime chart when I use XValueEx. I tried so hard, unfortunatly not much documentation or sample in this regard. Please help me out if you have any sample. Thank you Link to comment Share on other sites More sharing options...
Software FX Posted June 7, 2002 Report Share Posted June 7, 2002 There is no support for Real-Time-Scrollable-XY-Charts in Chart FX, that is why you are having so much trouble. The problem here is scrolling, in an X-Y chart, points are not evenly spaced so when a new points comes in, how much do you want to scroll, what if the new point that comes is actually to the left of the last point, XY charts don't necessarily go in one only direction, what if you have two or more series and you run into a situation where the last point of all the series can not be displayed in the same screen ? For all these reasons we decided that there is no way to define a real X-Y real time chart. We however provide the standard API for you to implement "specific" versions of XY real-time charts in which you will have some restrictions given your particular circumstances. You can always add data and modify current data, change the scroll view, etc. That is not what we call real-time in our docs. though. We call real-time chart to a series of API that make it easier and faster to create scrolling real-time charts, but this dos not include XY charts. We will be glad to help you out implementing specific features in your program. -- FP Software FX, Inc. Link to comment Share on other sites More sharing options...
