Programs written in QT before colleague, is one of the functions according to the detecting system of target location data, map track,
Detection system is submitted to the data at a time, every second of track is also should be updated in real time,
But the problem is in front of the 400 s painted track are all right, also no problem, zoom in to the 400 s, drawing track is automatically is broken, but still can see the target location data in the report, on behalf of the target location of the triangle icon also in go, but they were not dead reckoning, can only display the track before the 400 s,
Because this program colleagues have left, I took over, after drawing track figure this code is a function of the use of QCustomPlot garage, I wonder if you have great spirit in the BBS encountered similar problems, is how to solve?
Thank you very much!

Estimate stronghold is beyond the limit of customplot, lead to the back of the point not draw trajectory real-time rendering only need to display a part of the data should be enough

& lt; Br/& gt; Mean in front of the 400 s have reached the limit of qcustomplot map track, lead to the back of the track is to draw not to come out, that can only draw track while erasing, show only the last track is wow!

Hello, could you tell me how to draw how qcustomplot track, I couldn't draw the track is not normal

QT under Linux operating measurement software, which leads to the platform CPU share rose to 96%, with great spirit has met this kind of problem, solving!!!!!
