Chart Wheel WordPress Plugin

This plugin allows a blogger to enter a shortcode (in the WordPress HTML editor) such as [chart date="march 5 1970 4:52pm EST"] and a chart for that time will automatically generate in the post.

This is what the chart looks like:

Many different date and time formats are supported. See this documentation for details.

For example, [chart date="1970-03-05 16:52-0500"] and [chart date="3/5/70 21:52 UTC"] produce the exact same chart as [chart date="march 5 1970 4:52pm EST"]

You do not need to specify a time. The chart will default to 8:00 UTC.

[chart date="1970-03-05"]

If you just write [chart] you’ll get the chart for “right now.” (See this in action at Sasstrology.)

You can define the size:

[chart date="march 5 1970 4:52pm EST" size="400"] where "400" means 400 pixels in height and width.

The default Ascendant is 0 Aries. You can change the degree of the Ascendant. If you want to show 0 Virgo Rising, enter asc="150" because 0 Virgo is 150 degrees from 0 Aries.

[chart date="march 5 1970 4:52pm EST" size="400" asc="150"]

You can add a name to the top left of the chart:

[chart date="march 5 1970 4:52pm EST" size="400" asc="150" name="Jeffrey Kishner"]

The order of these 4 parameters does not matter, as long as they are preceded by “chart.”

Anticipated Frequently Asked Questions

Why can’t I draw up a chart for a specific location?
PlanetWatcher does not have an atlas.

How can I get this to work on my WordPress.com blog?
You can’t. You need a self-hosted blog.
