plotly coupled event to clear the previous data

how to clear the previous charts when clicked on other slide of chart ,i mean when totraj part is clicked it will render it's coupled barchart and so on but when we click on tototherstate it will render it's coupled chart or barchart that is attached to tototherstate ,the sub-barcharts of totraj will be there on this page , they won't disappear, how to clear all those sub-bar charts as soon as tototherstate is clicked
I hope I am not making you confuse,just tryna keep it as simple as that.

here's the reprex for the above given scenario
