CHARTSPREE

Make charts in seconds

Use our URL to inject charts into your website. The data is supplied via the URL, no Javascript required. Plus, if you need Lorem Ipsum charts, we've got you covered.

Example:

<img src="//chartspree.io/bar.svg?Foo=1,1,2,3,5">

Pies, Bars and Lines

There are 3 different types of charts. Choose one by changing the path.

Pies

chartspree.io/pie.svg?Things=5&Stuff=2

Bars

chartspree.io/bar.svg?Things=lorem_exp

Lines

chartspree.io/line.svg?Things=lorem_flat

Choose a Style

Just by adding _style=Stylename to the URL

Light (default)

chartspree.io/bar.svg?Foo=lorem_exp&_style=light

Dark

chartspree.io/bar.svg?Foo=lorem_exp&_style=dark

Supplying data

You can just append the data for the chart to the URL parameters.

Bars and Lines

Generally you provide DataSet=. For example:

chartspree.io/line.svg?Things=1,2,3

You can also have multiple datasets, like:

chartspree.io/line.svg?Some=1,2,3&Thing=2,3,4

Finally, you can add labels to the x axis:

chartspree.io/bar.svg?Likes=3,2,4&_labels=Jan,Feb,Mar

Pies

For pies it's mostly the same, except you have names for sections and one value per section.

chartspree.io/pie.svg?Some=1&Thing=2

Other fancy features

Here are some additional neat features that Chartspree provide.

Generate placeholder data

If you're prototyping and need placeholder charts, we have a solution for you. Instead of providing numbers, you can just use one of these keywords.

chartspree.io/bar.svg?Stuff=lorem_exp

chartspree.io/bar.svg?Stuff=lorem_hockey

chartspree.io/bar.svg?Stuff=lorem_bell

chartspree.io/bar.svg?Stuff=lorem_flat

Customize the appearance of (line) charts

<img src="http://chartspree.io/line.svg?Foo=lorem_hockey&_show_legend=false&_height=300px&_interpolate=cubic&_fill=true">

Show off with hover effects

Use an tag instead of images. This gives you fancy hover-states.

<object type="image/svg+xml" data="http://chartspree.io/line.svg?Some=lorem_flat&Stuff=lorem_flat&_interpolate=cubic &_fill=true&_height=300px"></object>

Configuring Chartspree

Take a look at the charts/settings.py file for a list of environment variables that should be set in order for Charts to work correctly.

You can set these environment variables by creating a new file called dev.env in the root of the project and then use Foreman to run the application.

foreman start -e dev.env
