Is there a subchart clear all or legend remove/ delete method ?

[Tapanhaz]

Question

I didn't found any subchart delete method. So I used same chart objects (previously removed indicator pane). That requires a full cleanup . After all lines, histograms removed, the legend is there . So it will show up twice if I used to show another indicator in the same pane.

We can set the chart height to 0 and proceed with new subchart but I think it will be good if we can fully clean the chart object and reuse it.

Code example

I didn't faced any such issue. Did your terminal shows any error?

Thanks for the compliment. This was developed using PyQt5.

Never had this issue using pyqt5. I think that you should keep track of lines and histograms after creation in subchart. Before reusing the subchart, check first if there are remaining lines/histograms. It is also possible that you are passing two columns with the same name to subchart. Other than that I have no idea.

I cann't able to find out where I made the mistake. On release, I cleared lines + histograms (version < 2.0)

I used dictionaries to track everything: indicators/subcharts. For every line/histogram created, it is recorded in dictionary. To delete, loop through dictionary. Hide subchart if any. Then delete dictionary key.

I didn't use chart.lines()/chart.histograms() to get the lines/histograms. I think I never had a problem with this from v 1.16 to 1.20. Just upgraded to v2 though

Thanks for the suggestion. Maybe that is the cause. I will try refactoring my code and let you know.
