<p>After <a href="http://www.tomfotherby.com/blog/index.php/2009/01/how-to-plot-dates-in-google-charts-api/" title="A post from  my blog" rel="nofollow ugc">working out how to plot time-based data using Google charts API</a>, I created a WordPress plugin to plot values stored in a custom field against the published-on date of WordPress blog posts that use the field.</p>
<h3>Usage Example</h3>
<p>I use this plugin to keep a track of my weight. I have a private WordPress journal with a custom field called “Weight (kgs)” and each week when I make my journal entry I fill in my weight in this custom field. I have page called “My Weight” which is empty but uses the <strong>Fotherplot</strong> Template.</p>
<p>The plugin outputs <a href="http://chart.apis.google.com/chart?&cht=lxy&chs=450x300&chma=10,10,10,10&chds=0,364,98.9,116.1&chg=0,5&chxt=y,x&chxl=0:|98.9|102.34|105.78|109.22|112.66|116.1|1:|20/Jan/08|11/Feb/08|17/Jul/08|18/Oct/08|10/Jan/09&chm=D,FF0000,0,-1,1|o,000000,0,-1,4|N,000000,0,-1,9&chd=t:0,8,15,22,50,79,180,224,263,273,290,350,357,364|103.4,102.9,102.3,100.9,99.3,98.9,103.4,110.5,112.9,109.7,110,116.1,113.4,110.67" title="Generated from Google Charts API" rel="nofollow ugc">a image</a> and a list of the relevant data, example:</p>

Fotherplot

A WordPress plugin for plotting some data in a custom field against time. It uses the Google charts API to render a simple line chart.

<p>Draws a graph of single set of date related data. Graph can be made public (i.e. sidebar widget or static page) and the data can be manipulated through dashboard. Many people use this plugin for weight tracking on their blogs (as do I), but it has been used for many other things as well. Only requirement – or rather a constraint – is that the horizontal axis of the graph shows dates. The vertical axis can hold any values. Each user can have their own graphs, which can be easily inserted in posts and pages.</p>
<h3>Content filter</h3>
<p>If you want to insert a graph in posts and/or pages, simply write a string similar to following in your post or page.</p>
<p>[[simple-graph n=1 x=0 y=0 trend=0 wkly=0 lm=0 ytd=0 uid=0 gid=0 ]]</p>
<p>Just replace the values as you wish. The ones above are default values, and if you don’t need to change the default value, you can simply omit that value from the string. I.e. [[simple-graph]] alone produces the graph with default values drawn from widget setup.</p>
<ul>
<li>n is number of widget options, from where default options (such as colours) are drawn</li>
<li>x is width, any positive value is acceptable</li>
<li>y is height, any positive value is acceptable</li>
<li>trend is whether trend graph is shown, 0 = no, 1 = yes</li>
<li>wkly is whether weekly averages are shown, 0 = no, 1 = yes</li>
<li>lm is whether only values from last month are shown, 0 = no, 1 = yes</li>
<li>ytd is whether only values from last year are shown, 0 = no, 1 = yes</li>
<li>uid is user ID of the graph owner (see WordPress dashboard -> Users)</li>
<li>gid is user-specific graph number, same as in widget control panel’s graph# selection</li>
</ul>
