嗨，我尝试制作一个简单的 jsxgraph 图，我可以在其中使用按钮切换电路板的一些属性。我正在使用角度，但我不明白为什么它不起作用。这是小提琴

我很高兴任何形式的帮助

 <div class="col-md-10">
    <div ng-controller="MyCtrl">
    <div id="jsxgbox" class="jxgbox " style="width:250px; height:250px;"></div>
    <button type="button" class="btn btn-primary" ng-model="showAxis" ng-click="showAxis = !showAxis">
    <span ng-show="showAxis">axis On</span>
    <span ng-show="!showAxis">axis Off</span></button>
    <button type="button" class="btn btn-primary" ng-model="showNav" ng-click="showNav = !showNav"> <span ng-show="showNav">Navigation On</span>
    <span ng-show="!showNav">Navigation Off</span></button>
    </div>
</div>

var myApp = angular.module('myApp', []);
function MyCtrl($scope) {
$scope.showAxis = true;
$scope.showNav = false;
$scope.axisOn = true
$scope.board = JXG.JSXGraph.initBoard('jsxgbox', {
    unitX: 10, // this are the lighter gray lines parallel ro the y axis
    unitY: 10,
    axis: $scope.showAxis,
    showNavigation: $scope.showNav,
    showCopyright: false,
    grid: true,
    wheel: true,
    keepaspectratio: true,
    needshift: false,
    boundingbox: [-5, 5, 5, -5] // upperleft corner ( x1,y1) bottom right corner (x2,y2)
});
}

在 JSXGraph 中，默认轴和导航栏的行为与其他元素略有不同。导航栏只能通过直接将 CSS 属性设置为 HTML div 来关闭。这是您的示例的工作版本。如果代码没有完善，我很抱歉。这是我的第一个 angual.js 应用程序。但是很高兴看到 JSXGraph 和 angualrs.jus 是如何协同工作的。
