No recent updates? This plugin once went 9 years without an update. It probably works!<\/p>\n\n
WordPress already lets you attach time-based custom data to posts. Tally Graph lets you plot that data over time using the Google Chart API. Any numeric data will work, whether it is related to athletic training, profits, environmental footprint, weight loss, or any topic you care about.<\/p>\n\n
Tally Graph is easier to use than direct Google Chart API calls, but may not be what you need if:<\/p>\n\n
Move on to the Other Notes tab for details.<\/p>\n\n
You'll want to do two things to use Tally Graph:<\/p>\n\n
Tally Graph looks in WordPress custom fields<\/a> for data to pass on to the Google Chart API. As indicated by those instructions, a custom field consists of a key and value. You'll make up the key. The value must be some kind of number. In the next step you'll use the key name to tell Tally Graph which custom field data to use.<\/p>\n\n If you want to enter data without publishing a post, just put the custom fields on a dummy post and check \"Keep this post private\". You may still want to edit the post date.<\/p>\n\n Say you have a bunch of posts with the custom field key \"Marbles Lost\". You may feel like you've been losing your marbles faster recently, but you're not sure, so you write a new post (or a page) containing this shortcode:<\/p>\n\n The Tally Graph plugin will replace that shortcode with a bar chart of how many marbles you've lost each month for the past six months. Those are default settings you can change with some more parameters.<\/p>\n\n That shortcode results in a 300 pixel wide, 220 pixel high graph of your marbles lost in the 14 days prior to May 1st, 2008.<\/p>\n\n Shortcodes are great in post and page content, but if you want a graph somewhere else on your site, like in a sidebar, you'll need a template tag<\/a>. Aside from the different format, it works the same:<\/p>\n\n That makes a nice sidebar graph of marbles lost over 4 weeks, up to the date of the last post displayed.<\/p>\n\n Read the Usage section first.<\/p>\n\n You type a tag directly into a post or page using WordPress shortcode format<\/a>. To put a tag in a theme template, use template tag with querystring parameters<\/a>. Both formats take the same parameters listed below.<\/p>\n\n This tag is replaced with an image created with the Google Chart API.<\/p>\n\n Shortcode: Template Tag: Parameters:<\/p>\n\n key<\/strong> - Required.<\/p>\n\n The key name of the custom field to use for the graph. Multiple keys can be included, separated by a comma.<\/p><\/li>\n tally_interval<\/em><\/p>\n\n valid values: this is the interval of time over which the custom field values are tallied.<\/p><\/li>\n label_interval<\/em><\/p>\n\n valid values: this is the interval of time that is labeled at the bottom of the graph<\/p><\/li>\n interval_count<\/em><\/p>\n\n Default is This is the number of intervals to include in the graph.<\/p><\/li>\n to_date<\/em><\/p>\n\n Valid values include several date formats, like The graph is constructed backward in time from this date.<\/p><\/li>\n method<\/em><\/p>\n\n Valid values are The The The no_cache<\/em><\/p>\n\n Valid values: Turn off URL caching. Rarely used - only when the same graph appears more than once on a page.<\/p><\/li>\n chs<\/em><\/p>\n\n Default is This is a Google Chart API<\/a> parameter, the chart size in pixels.<\/p><\/li>\n cht<\/em><\/p>\n\n Default is This is a Google Chart API<\/a> parameter, the chart type. Any other Google Chart API parameters<\/a> are passed along, so you can go nuts with all the options. You'll probably use at least If you want to create your own image tag in a template, this tag will give you only the URL for the chart.<\/p>\n\n Template Tag: Parameters are the same as the Install using any [standard plugin installation method][http:\/\/codex.wordpress.org\/Managing_Plugins#Installing_Plugins].<\/p>\n\n\n You can get by with very little techyness, just WordPress custom fields and shortcodes. They're really not bad - look over the Usage section under Other Notes. It's not a point-and-click interface either, but it is easier than building your charts from scratch.<\/p>\n\n If you do want to get adventurous, you can have fancier charts in more places.<\/p><\/dd>\n Check the forum<\/a>, there's at least one oldie-but-goodie<\/a>.<\/p><\/dd>\n As of WordPress 3.3 you must check a box in the \"Screen Options\" area in the upper right of the post editor page to make the custom field interface appear.<\/p><\/dd>\n\n<\/dl>\n\n\nVisualize Data<\/h4>\n\n

Do I have to know about this Google API thing, or anything else techy?<\/h3><\/dt>\n
Are there any examples?<\/h3><\/dt>\n
Where are the custom fields?<\/h3><\/dt>\n
