I have been using the "old" quinn curtis realtime graphics for visual basic 6.0 and found that the sweepgraph was really the best solution for my application. I downloaded the trialversion of the new .NET version of QC and I can't find this type. Is this type removed from the library ? If this is the case, why ?
Regards, UED |

| You are correct, we did not implement sweep graphs in the first version of the Real-Time Graphics Tools for .Net, though we did consider and look at it. The reason is that we could not find a clean way to implement it. It requires two constantly changine coordinate systems, one in front of the sweep line, and one behind the sweep line. Nothing precludes us from adding it the future, depending on demand. You are the first to lament its passing. |

Hey, thanks for your quick answer,
Regarding the sweep graph, I thought this type was the easiest graph to implement, you only need to write the datapoints from left to right, no need to scroll or change anything, and when the sweep reaches the right side start from beginning and overwrite earlier datapoints. Are we talking about different things here? |

| Actually, even in Windows software sweep graphs were the hardest to implement, though they might have been easy to use. The implementation was a kludge that forced that use of coordinate system that did not actually match the xy values of the data points being plotted, causing a host related problems when it came to updating axis labels, rescaling, and positioning of markers and data cursors. We want to avoid these types of problems. |
