Changing axis min/max on an existing plot using Flot JQuery Library
提问by jfaghihnassiri
I've created a series of plots using the flot library, which are all displayed on a single page. Is there a way to update the X axis min and max options (options.xaxis.min, options.axis.max) values WITHOUT re-plotting the plots ($.plot('placeholder',data,options))?
我使用 flot 库创建了一系列图，它们都显示在一个页面上。有没有办法更新 X 轴的最小值和最大值选项（options.xaxis.min，options.axis.max）而不重新绘制图（$.plot('placeholder',data,options)）？
I found this solution: http://osdir.com/ml/flot-graphs/2012-02/msg00064.htmlWhich suggests that the following line would do it, but it does not work for me - the plots visible min and max are not modified based on this call.
我找到了这个解决方案：http: //osdir.com/ml/flot-graphs/2012-02/msg00064.html这表明以下行可以做到，但它对我不起作用 - 图中可见的最小值和最大值不会基于此调用进行修改。
monitorGraph.getOptions().xaxis[0].max = xaxis.max;
Any tips on updating the graphs xaxis max and min values would be greatly appreciated!
任何有关更新图表 xaxis 最大值和最小值的提示将不胜感激！
EDIT: Solution Below
编辑：下面的解决方案
The following code will take an existing plot, update the range that is visible, and redraw it in a very light and efficient way.
以下代码将采用现有绘图，更新可见范围，并以一种非常轻松高效的方式重新绘制它。
plot.getOptions().xaxis[0].min = time.start;
plot.getOptions().xaxis[0].max = time.end;
plot.setupGrid();
plot.draw();

After you set the value of the yaxis max height, try
设置 yaxis 最大高度的值后，请尝试
yourPlot.setupGrid();
Not sure if it'll be as smooth as you want but I think it does the trick.
不确定它是否会像你想要的那样顺利，但我认为它可以解决问题。

You can also dynamically modify MIN/MAX parameters in axis options:
您还可以在轴选项中动态修改 MIN/MAX 参数：
plot.getAxes().xaxis.options.min = 0;
plot.getAxes().xaxis.options.max = 999;
plot.setupGrid();
plot.draw();
