This is provided in the RGraph Archive.</li><li>Use another browser entirely.

83        <p>
84            Since 24th May 2010 you have had the ability to adjust your so if you want to see the charts interactively. Currently the Bar chart, Line chart,
85            Progress Bar, Rose chart and the Radar have this facility. Some chart types use multiple event handlers and as such
86            are unlikely to work well with other dynamic features. The Line chart is an example of this, and whilst it does work
87            with the context menu (and so the full canvas zoom), it is unlikely to work with other dynamic features.
88        </p>
89   
90   
91        <p>
92            At the current time this feature on the Bar and Line charts doesn't work with X axis in the center.
93        </p>
94   
95   
96        <p>
97            If your intention is to make some sort of interactive console, new HTML5 input types may also be of interest (for example the new <i>range</i> input type
98            which gives you a "slider bar"). Eg (Chrome/Safari/Opera):
99        </p>
100   
101        <p style="text-align: center">
102            <input type="range" min="0" max="100" value="76" onchange="document.getElementById('range_result').value = this.value"/>
103            <input type="text" id="range_result" size="3" value="76" />
104        </p>
105       
106        <h4>Note</h4>
107       
108        <p>
109            Since interactivly adjusting a chart involves completely redrawing it, having a lot of them on one page can cause
110            slower updates. For this reason each example chart is on its own page:
111        </p>
112       
113        <ul>
114            <li><a href="adjusting_bar.html">Bar chart</a></li>
115            <li><a href="adjusting_gantt.html">Gantt chart</a></li>
116            <li><a href="adjusting_hprogress.html">HProgress bar</a></li>
117            <li><a href="adjusting_line.html">Line chart</a></li>
118            <li><a href="adjusting_radar.html">Radar chart</a></li>
119            <li><a href="adjusting_rose.html">Rose chart</a></li>
120            <li><a href="adjusting_thermometer.html">Thermometer chart</a></li>
121            <li><a href="adjusting_vprogress.html">VProgress bar</a></li>
122        </ul>
123       
124        <h4>DOM2 event handlers</h4>
125       
126        <p>
127            In January 2011 all adjusting was converted to DOM2 event handling. This makes adjusting work much better with other
128            dynamic features.
