@jsulm The primary cause of our error is the misuse of the integer parameter rather than float parameter in the drawling function. Sorry to reply so late and we really appreciate a lot for your help.

@loserlovey 这个应该是不行滴，外面是包了一个QWizard，你应该是改不了的

@dilipa I have never worked with QTestEventList. I see no obvious error in your handling. You may have to check the Qt version you are using and possibly start out with the test provided in the documentation.

SerialPort_Status = (char)(serialport1->write((char*)PC_CMD_Stop,10)); my_serialport1->waitForBytesWritten();//add this serialport1->close();

添加一个QT_CHARTS_USE_NAMESPACE宏看看

请问该怎么解决这个问题？
