QCustomPlot clear Data
I have qcustomplot grapich. It have lots of line ploting before. I want to clear this ploting data.
There is 2 code which is find. but these codes delete graph (0-1-2-3);
I want to clear graph data not graph completely. How can I figure out ?
yes ı wrote.
Is it solved?
no. all about deleting not cleaning
I think Ian explained rather clearly what you can or can not do. I don't see how we could add to that.
Since the 2.0 beta version.
Alternatively, you can simply give it an empty data list.
Then its "Clear".
I wrote this code and problem solved. Thank you mrjj !!!
ui->qcustom->graph(0)->data()->clear(); ui->qcustom->graph(1)->data()->clear(); ui->qcustom->graph(2)->data()->clear(); ui->qcustom->replot();
@kshegunov I dont want to set empty data . I was searching for fallowing code which is shared by mrjj.
I'm facing some issue with ui->qcustom->graph(0)->data()->clear();. It is not working for me.
Data container is not getting cleared, even if i call clear() and then replot().
I have the same problem as indu2. Calling clear() and replot(), nothing happens
clearPlottables() does not work because it deletes the object entirely.
Maybe ask the author of customplot about how to do it correctly then?
