  • CSS For Bar Graphs(maybe old)

    Having a working knowledge of XHTML and CSS when developing applications
    is a big help in knowing what can be done client-side and what should be
    generated server-side.

    Recently we’ve had to tackle some interesting visualizations which we coded in XHTML and CSS. The method we used, while fairly simple, was a big help to the engineer and created a very flexible and inexpensive solution. We thought we would share our solution and code in case anyone else ran against similar situations.

    Update

    I posted a live example page with everything in tact. So far I’ve only been able to test in Firefox 1.0.7, Firefox 1.5, IE 6, Safari 1.3.3, and Opera 9(TP1). You can view it here.

    Basic CSS Bar Graph

    This is a simple bar graph we developed for a tool we’re releasing shortly for our client. The concept is simple, utilize the percentage width abilities of CSS to accurately portray a percentage bar graph.

    <style>
        dl { 
            margin: 0; 
            padding: 0;                     
        }
        dt { 
            position: relative; /* IE is dumb */
            clear: both;
            display: block; 
            float: left; 
            width: 104px; 
            height: 20px; 
            line-height: 20px;
            margin-right: 17px;              
            font-size: .75em; 
            text-align: right; 
        }
        dd { 
            position: relative; /* IE is dumb */
            display: block;                 
            float: left;     
            width: 197px; 
            height: 20px; 
            margin: 0 0 15px; 
            background: url("g_colorbar.jpg"); 
         }
         * html dd { float: none; } 
        /* IE is dumb; Quick IE hack, apply favorite filter methods for 
        wider browser compatibility */
    
         dd div { 
            position: relative; 
            background: url("g_colorbar2.jpg"); 
            height: 20px; 
            width: 75%; 
            text-align:right; 
         }
         dd div strong { 
            position: absolute; 
            right: -5px; 
            top: -2px; 
            display: block; 
            background: url("g_marker.gif"); 
            height: 24px; 
            width: 9px; 
            text-align: left;
            text-indent: -9999px; 
            overflow: hidden;
         }
    </style>
    <dl>
        <dt>Love Life</dt>
        <dd>
            <div style="25%;"><strong>25%</strong></div>
        </dd>
        <dt>Education</dt>
        <dd>
            <div style="55%;"><strong>55%</strong></div>
        </dd>
        <dt>War Craft 3 Rank</dt>
        <dd>
            <div style="75%;"><strong>75%</strong></div>
        </dd>
    </dl>

    Vertical CSS Bar Graph

    In this third example, we utilize the same principle vertically and reproduce it multiple times to create a more complex graph. This particular solution was a relief the to client and engineer as all they had to do was calculate percentages, and the look of the graph was much better than their stock graphing component.

    <style>
        #vertgraph {                    
            width: 378px; 
            height: 207px; 
            position: relative; 
            background: url("g_backbar.gif") no-repeat; 
        }
        #vertgraph ul { 
            width: 378px; 
            height: 207px; 
            margin: 0; 
            padding: 0; 
        }
        #vertgraph ul li {  
            position: absolute; 
            width: 28px; 
            height: 160px; 
            bottom: 34px; 
            padding: 0 !important; 
            margin: 0 !important; 
            background: url("g_colorbar3.jpg") no-repeat !important;
            text-align: center; 
            font-weight: bold; 
            color: white; 
            line-height: 2.5em;
        }
    
        #vertgraph li.critical { left: 24px; background-position: 0px bottom !important; }
        #vertgraph li.high { left: 101px; background-position: -28px bottom !important; }
        #vertgraph li.medium { left: 176px; background-position: -56px bottom !important; }
        #vertgraph li.low { left: 251px; background-position: -84px bottom !important; }
        #vertgraph li.info { left: 327px; background-position: -112px bottom !important; }
    </style>
    <div id="vertgraph">
        <ul>
            <li class="critical" style="height: 150px;">22</li>
            <li class="high" style="height: 80px;">7</li>
            <li class="medium" style="height: 50px;">3</li>
            <li class="low" style="height: 90px;">8</li>
            <li class="info" style="height: 40px;">2</li>
        </ul>
    </div>

    We hope you enjoyed our examples and find new uses and variations for
    the concept. Drop us a line if you have any other interesting
    visualizations using XHTML and CSS and we’ll post them here.
