112    <br />&nbsp;<br />
113    <h2>RGraph_png</h2>
114        <p>
115            This controls the appearance of the PNG image which is shown when you use the context menu option <i>RGraph.showPNG()</i>.
116        </p>
117   
118    <a name="RGraph_palette"></a>
119    <br />&nbsp;<br />
120    <h2>RGraph_palette</h2>
121        <p>
122            This controls the appearance of the mini-palette that can be used with annotating.
123        </p>
124   
125    <a name="RGraph_tooltip"></a>
126    <br />&nbsp;<br />
127    <h2>RGraph_tooltip</h2>
128        <p>
129            This controls the appearance of tooltips. The default is to have them look like Windows tooltips.
130        </p>
131
132    <a name="RGraph_contextmenu"></a>
133    <br />&nbsp;<br />
134    <h2>RGraph_contextmenu</h2>
135        <p>
136            This controls how context menus appear. The default is similar to the look that Windows XP has.
137        </p>
138
139    <a name="RGraph_contextmenu_item"></a>
140    <br />&nbsp;<br />
141    <h2>RGraph_contextmenu_item</h2>
142        <p>
143            This controls how individual items on the context menu will appear, for example the default has roughly 25px padding-left
144            to accomodate the left bar.
145        </p>
146
147    <a name="RGraph_contextmenu_background"></a>
148    <br />&nbsp;<br />
149    <h2>RGraph_contextmenu_background</h2>
150        <p>
151            This is the Windows XP style left vertical bar. By default this is light grey.
152        </p>
153   
154    <a name="RGraph_zoom_window"></a>
155    <br />&nbsp;<br />
156    <h2>RGraph_zoom_window</h2>
157        <p>
158            This is the class to use if you want to customise the mini-zoom window.
159        </p>
160   
161    <a name="RGraph_zoomed_canvas"></a>
162    <br />&nbsp;<br />
163    <h2>RGraph_zoomed_canvas</h2>
164        <p>
165            This is the class to use if you want to customise the full canvas zoom.
166        </p>
167   
168    <a name="RGraph_zoomed_area"></a>
169    <br />&nbsp;<br />
170    <h2>RGraph_zoomed_area</h2>
171        <p>
172            This is the class to use if you want to customise the zoomed area.
173        </p>
174   
175    <a name="ModalDialog_background"></a>
176    <br />&nbsp;<br />
177    <h2>ModalDialog_background</h2>
178        <p>
179            This class controls the dark semi-opaque background for the ModalDialog.
180        </p>
181   
182    <a name="ModalDialog_dialog"></a>
183    <br />&nbsp;<br />
184    <h2>ModalDialog_dialog</h2>
185        <p>
186            This class controls the ModalDialog itself.
187        </p>
188   
189    <a name="ModalDialog_topbar"></a>
190    <br />&nbsp;<br />
191    <h2>ModalDialog_topbar</h2>
192        <p>
193            This class controls the top bar for the ModalDialog. You could, for example, use the <i>display</i> CSS property to
194            hide this if you don't want it.
195        </p>
196   
197    <a name="example"></a>
198    <br />&nbsp;<br />
199    <h2>Example usage</h2>
200        <p>
201            Here is an example of using the CSS classes. At the time of writing, some of the items here were only implemented in newer
202            web browsers:
203        </p>
204
205        <pre class="code">
206&lt;style&gt;
207    .RGraph_png {
208    }
209
210    .RGraph_palette {
211    }
212
213    .RGraph_tooltip {
214    }
215   
216    .RGraph_contextmenu {
217    }
218   
219    .RGraph_contextmenu_background {
220    }
221   
222    .RGraph_contextmenu_item {
223    }
224   
225    .RGraph_zoom_window {
226    }
227   
228    .RGraph_zoomed_canvas {
229    }
230   
231    .RGraph_zoomed_area {
232    }
233   
234    .ModalDialog_background {
235    }
236   
237    .ModalDialog_dialog {
238    }
239   
240    .ModalDialog_topbar {
241    }
242&lt;/style&gt;
243</pre>
244
245<a name="important"></a>
246<br />&nbsp;<br />
247<h2>! important</h2>
248   
249    <p>
250        If you're attempting to override default styles, then because of the ordering (ie the script is setting the style  AFTER
251        your own CSS) you may need to use the "! important" modifier, for example:
252    </p>
253
254    <pre class="code">
255&lt;style&gt;
256    .RGraph_tooltip {
257        background-color: white ! important;
258    }
259&lt;/style&gt;
260</pre>
261</body>
262</html>
