在我们的 Angular 应用程序中,我们使用highcarts-ng来实现HighCharts。
这是图表最大化和最小化功能,它有效:
function expandChartPanel() {
vm.chartMaxed = !vm.chartMaxed;
viewHeader = ScopeFactory.getScope('viewHeader');
highChart = ScopeFactory.getScope('highChart');
var chart = highChart.chartObject;
var highChartContainer = document.getElementById("highchart-container");
var highChartContainerWidth = document.getElementById('highchart-container').clientWidth;
var highChartContainerHeight = document.getElementById('highchart-container').clientHeight;
var windowWidth = window.innerWidth;
var windowHeight = window.innerHeight;
if (vm.chartMaxed) {
vs.savedWidth = highChartContainerWidth;
vs.savedHeight = highChartContainerHeight;
console.log('savedWidth = ', vs.savedWidth);
console.log('savedHeight = ', vs.savedHeight);
root.chartExpanded = true;
viewHeader.vh.chartExpanded = true;
highChart.highChartMax = true;
highChartContainerHeight = document.getElementById('highchart-container').clientHeight;
windowWidth = window.innerWidth;
windowHeight = window.innerHeight;
highChart.chartConfig.size.width = windowWidth;
highChart.chartConfig.size.height = windowHeight - 220;
chart.setSize(windowWidth, windowHeight - 220);
}
else {
root.chartExpanded = false;
viewHeader.vh.chartExpanded = false;
highChart.highChartMax = false;
highChart.chartConfig.size.width = vs.savedWidth;
highChart.chartConfig.size.height = vs.savedHeight;
chart.setSize(vs.savedWidth, vs.savedHeight);
}
highChart.restoreChartSize();
}
这是回流功能:
function restoreChartSize() {
console.log('restoreChartSize');
if (!vs.chartObject.reflowNow) {
vs.chartObject.reflowNow = vs.chartObject.reflowNow = function() {
this.containerHeight = this.options.chart.height || window.window.HighchartsAdapter.adapterRun(this.renderTo, 'height');
this.containerWidth = this.options.chart.width || window.window.HighchartsAdapter.adapterRun(this.renderTo, 'width');
this.setSize(this.containerWidth, this.containerHeight, true);
this.hasUserSize = null;
}
}
vs.chartObject.reflowNow();
}
上面的这个 reflow 函数在这个jsFiddle中完美运行,但在我们的应用程序中却不行。
我们的 HighChartsDirective 文件的完整 Gist 文件。
单击最大化后,图表将展开到浏览器窗口的完整大小,但在拖动以调整浏览器窗口大小后,我调用了该restoreChartSize
函数,该函数激活了回流。
但是图表的大小不会自动调整为 100% 100%,它会回到图表的先前大小:(
在最大化功能之后:
现在在调整浏览器窗口大小后:
window.onresize = function(event) {
console.log('window resizing...');
highChart = ScopeFactory.getScope('highChart');
highChart.restoreChartSize();
console.log('highChart.chartConfig = ', highChart.chartConfig);
};
^ 回到较小的静态尺寸,而不是 100% 的自动尺寸
