Refresh/Reload Flot In Javascript
提问by dhulihan
Hey Guys, does anyone know how to reload a flot graph in javascript? For instance, I want to redraw the graph every time an input value is changed. I tried experimenting with a few methods found in the flot API, such as draw()and setupGrid()without any luck.
嘿伙计们，有谁知道如何在 javascript 中重新加载浮动图？例如，我想在每次更改输入值时重新绘制图形。我尝试尝试了在Flot API 中找到的一些方法，例如draw()和setupGrid() ，但没有任何运气。
Here's some example code:
下面是一些示例代码：
$("#some_input_box").change(function(){
plot.draw(); // redraw graph
});

You are on the right track with drawand setupGrid, here's what you need to do:
您在正确的轨道上使用draw和setupGrid，这是您需要做的：
var plot = $.plot($('#placeholder'),data,options);
//time passes, you now want to replot
var newData = [[0,2],[1,3],[2,5]];
plot.setData(newData);
plot.setupGrid(); //only necessary if your new data will change the axes or grid
plot.draw();
Alternatively, it's not too much worse to just re-call $.plot. The above way is more efficient, but...
或者，只是重新调用$.plot. 上面的方法效率更高，但是...
