当我单击检查时，我有一个函数，它一次又一次地调用函数

Question

demo() 函数是一个饼图，每当我切换它时，我都会有一个带有复选框切换按钮的切换按钮 demo() 函数正在调用，这很好，但每当我单击复选框（切换按钮）时，它都会创建饼图的副本）它更改了图表周围的值，该值工作正常，但它一次又一次地调用饼图函数，并且使用切换按钮创建多个饼图。我应该做什么才能获得新图表一次，我的意思是它不会创建饼图的副本并删除旧的图表？

async function renderTradesInfo() {
    let tradeOrders = await TradesInformation();

    totalTrades = tradeOrders.data.total_orders;
    

    let ThirtydOrders = tradeOrders.data.orders_placed_30d;
    let ThirtydOrder = `${ThirtydOrders}`;
    let thirtydOrderTrade=  $("#tradeCharts").find("#thirtydOrderTrade");
    thirtydOrderTrade.html(ThirtydOrder);

    let checkedValue = $('#checkbox1').is(':checked');
    if(!checkedValue){
        closedOrdersTrade(tradeOrders);
        totalTrades = tradeOrders.data.total_orders;
        demo(totalTrades);
    }

    $('#checkbox1').on('change', function () {

        if ($(this).is(':checked')){
            let openProfitOrders = tradeOrders.data.open_profit_orders;
            let openProfitOrder = `${openProfitOrders} Profit`;
            let tradeChartProfit=  $("#tradeCharts").find(".tradeChartProfit");
            tradeChartProfit.html(openProfitOrder);
        
            let openLossOrders = tradeOrders.data.open_loss_orders;
            let openLossOrder = `${openLossOrders} Loss`;
            let tradeChartLoss=  $("#tradeCharts").find(".tradeChartLoss");
            tradeChartLoss.html(openLossOrder);
            
            // totalTrades = tradeOrders.data.open_orders;
            demo(totalTrades);
        }
        else {
            closedOrdersTrade(tradeOrders);
            // totalTrades = tradeOrders.data.closed_orders;
            demo(totalTrades);
        }
     
     });
}

这是我想在切换时更新的饼图函数，但它正在创建新的饼图
