用Java刷新/重新加载Flot [英] Refresh/Reload Flot In Javascript

问题描述

大家好，有人知道如何在javascript中重新加载浮动图吗?例如，我想在每次输入值更改时重画图形.我尝试尝试在 flot API 中找到的一些方法，例如 draw()和 setupGrid()，没有任何运气.

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.

下面是一些示例代码:

$("#some_input_box").change(function(){
   plot.draw(); // redraw graph
});     

推荐答案

您在使用draw和setupGrid的正确轨道上，这是您需要做的:

You are on the right track with draw and setupGrid, here's what you need to do:

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();

或者，重新调用$.plot也不会太糟.上面的方法更有效，但是...

Alternatively, it's not too much worse to just re-call $.plot. The above way is more efficient, but...
