当chart图遇上bootstrap的TAB切换 无宽高问题？

.tab-content > .tab-pane,
.pill-content > .pill-pane {
   display: block; /* undo display:none */
   height: 0; /* height:0 is also invisible */
   overflow-y: hidden; /* no-overflow */
}
.tab-content > .active,
.pill-content > .active {
   height: auto; /* let the content decide it */
} /* bootstrap hack end */
