现在有三张echarts的图，通过swiper轮播，使用鼠标滚轮控制，但是只能滚动两张图

<div class="swiper-container">
    <div class="swiper-wrapper">
        <div class="swiper-slide">
            <div class="dbidc-ip-info">
                <div class="item-title">
                    <span>IP分配</span>
                    <span></span>
                </div>
                <div id="ip-data-bdidc" style="width: 512px;height:190px;"></div>
            </div>
        </div>
        <div class="swiper-slide">
            <div class="dbidc-rack-info">
                <div class="item-title">
                    <span>机架分配</span>
                    <span></span>
                </div>
                <div id="rack-data-bdidc" style="width: 512px;height:190px;"></div>
            </div>
        </div>
        <div class="swiper-slide">
            <div class="dbidc-user-info">
                <div class="item-title">
                    <span>用户分配</span>
                    <span></span>
                </div>
                <div id="user-data-bdidc" style="width: 512px;height:190px;"></div>
            </div>
        </div>
    </div>
    <!-- Add Arrows -->
    <div class="swiper-button-next"></div>
    <div class="swiper-button-prev"></div>
    <!-- Add Pagination -->
    <div class="swiper-pagination"></div>
</div>

     $(function () {
        var swiper = new Swiper('.swiper-container', {
            //pagination: {
            //    el: '.swiper-pagination',
            //    dynamicBullets: true,
            //},
            mousewheel: true,
            observer:true,//修改swiper自己或子元素时，自动初始化swiper
            observeParents:true//修改swiper的父元素时，自动初始化swiper
        });
    });

你是Swiper5 版本吧，回退到swiper4.4.2 版本就行了，应该是新版本迁移有个状态没有清理
