>>> [!note] Migrated issue <!-- Drupal.org comment --> <!-- Migrated from issue #198854. --> Reported by: [snufkin](https://www.drupal.org/user/58645) >>> <p>Description: Google Chart is a great lightweight web tool that returns different charts, plots and graphs by URL variables This gives it a certain limit regarding the dataset (so be sure to implement a validating function that checks this and tells the user his dataset is not completely seen on the graph), but in return you can embed dynamical graphs without having any rendering task on your server. This is great for fast data visualization, and you even spare your server's CPU and bandwidth for these images.</p> <p>You will need to write a module that provides easy to use functions for other modules. There are several encodings available for the dataset, as well as ugly abbreviations of theming your chart. With a helper module to create a graph a developer should be able to create a plot just by passing a dataset and a settings array to your functions that return the URL of the requested graph.</p> <p>Example:</p> <div class="codeblock"> <pre><span style="color: #000000"><span style="color: #0000BB">&lt;?php<br>$settings</span><span style="color: #007700">[</span><span style="color: #DD0000">'color1'</span><span style="color: #007700">] = </span><span style="color: #DD0000">'#00000'</span><span style="color: #007700">;<br></span><span style="color: #0000BB">$settings</span><span style="color: #007700">[</span><span style="color: #DD0000">'color2'</span><span style="color: #007700">] = </span><span style="color: #DD0000">'#ffffff'</span><span style="color: #007700">;<br></span><span style="color: #0000BB">$settings</span><span style="color: #007700">[</span><span style="color: #DD0000">'type'</span><span style="color: #007700">] = </span><span style="color: #DD0000">'bar'</span><span style="color: #007700">;<br></span><span style="color: #0000BB">$data</span><span style="color: #007700">[] = {</span><span style="color: #0000BB">5</span><span style="color: #007700">,</span><span style="color: #0000BB">4</span><span style="color: #007700">,</span><span style="color: #0000BB">5</span><span style="color: #007700">,</span><span style="color: #0000BB">6</span><span style="color: #007700">,</span><span style="color: #0000BB">8</span><span style="color: #007700">,</span><span style="color: #0000BB">1</span><span style="color: #007700">,</span><span style="color: #0000BB">12</span><span style="color: #007700">};<br></span><span style="color: #0000BB">$url </span><span style="color: #007700">= </span><span style="color: #0000BB">googlechart_get_graph</span><span style="color: #007700">(</span><span style="color: #0000BB">$data</span><span style="color: #007700">, </span><span style="color: #0000BB">$settings</span><span style="color: #007700">);<br></span><span style="color: #0000BB">?&gt;</span></span></pre></div> <p>if the developer wants this graph, he/she simply writes<br> </p><div class="codeblock"> <pre><span style="color: #000000"><span style="color: #0000BB">&lt;?php<br>&nbsp;</span><span style="color: #007700">print </span><span style="color: #DD0000">"&lt;img src=" </span><span style="color: #007700">. </span><span style="color: #0000BB">$url </span><span style="color: #007700">. </span><span style="color: #DD0000">" /&gt;" <br></span><span style="color: #0000BB">?&gt;</span></span></pre></div> <p> Try writing separate functions for each task.</p> <p>What you need to do for this task:<br> * implement such a module<br> * write a complete documentation for the available settings and options</p> <p>Since the applicant does not necessarily has a CVS account, in that case he/she can submit the module directly to the relevant issue queue. Documentation should be added to the drupal handbook section.</p> <p>Suggested time for the project:<br> 4-5 days</p> <p>Resources: <a href="http://code.google.com/apis/chart/">http://code.google.com/apis/chart/</a><br> Primary contact: snufkin</p>
