I have a QCustomPlot widget in my ui as follows:
ui->plot_widget
also I have another QCustomPlot object in my cpp file as follows:
QCustomPlot *plot=new QCustomPlot();
I want to add plot data into ui->plot_widget data.
If I use ui->plot_widget=plot the widget parent of ui->plot_widget will be destroyed and my ui does not update ui->plot_widget.
How can I add plot data into ui->plot_widget data?
