Question

I am new to javascripting and jquery. I am drawing charts using flot in which i have 2 Bar graphs…

My first bar graph

<div id="bar1" style="width:600px;height:300px;"></div>
$(function () {

var css_id = "#bar1";
var data = [
    {label: 'foo',color:'red', data: [[1,300], [2,300], [3,300], [4,300], [5,300]]},
    {label: 'bar',color:'blue', data: [[1,800], [2,600], [3,400], [4,200], [5,0]]},
    {label: 'baz',color:'green', data: [[1,100], [2,200], [3,300], [4,400], [5,500]]},
];
var options = {
    series: {stack: 0,
             lines: {show: false, steps: false },
             bars: {show: true, barWidth: 0.4, align: 'center',},},
    xaxis: {ticks: [[1,'One'], [2,'Two'], [3,'Three'], [4,'Four'], [5,'Five']]},
};

$.plot($(css_id), data, options);

});​

My second graph

<div id="bar2" style="width:600px;height:300px;"></div>
var data = [
    {label: 'foo', color:'red', data: [[1,300], [2,300], [3,300], [4,300], [5,300]]},
    {label: 'bar', color:'blue', data: [[1,800], [2,600], [3,400], [4,200], [5,0]]},
    {label: 'baz', color:'yellow', data: [[1,100], [2,200], [3,300], [4,400],   [5,500]]},
    ];

$.plot($("#bar2"), data, {
series: {
    stack: 1,
    bars: {
        show: true,
        barWidth: 0.6,
        fill:1
    }
}
});​

Now i have a click event of a button

$(document).ready(function() {
......
});

Now what should i write on the occurance of the button event such that i dynamically change my bar graphs from <div id="bar1"> to <div id="bar2">

Answer 1

If i understand the question correctly you want to hide/show each div on the press of a button …. first hide one of the <div> using style="display:none" and then use the following code to toggle both on click of a button

$(document).ready(function() {
   $('#idofbutton').click(function() {
      $('#bar1,#bar2').toggle();
   });
});

Using toggle() on both with hide the currently shown div and show the currently hidden div (hope that makes sense !)
