|
Logarithmic |
|
----------- |
|
|
|
``logarithmic`` |
|
|
|
You can set the scale to be logarithmic: |
|
|
|
.. pygal-code:: |
|
|
|
chart = pygal.Line(logarithmic=True) |
|
values = [1, 3, 43, 123, 1231, 23192] |
|
chart.x_labels = map(str, values) |
|
chart.add('log example', values) |
|
|
|
.. caution:: |
|
|
|
Negative values are ignored, interpolation might be broken if it goes below zero... |
|
|
|
|
|
Custom css and js |
|
----------------- |
|
|
|
``base_css, base_js`` |
|
|
|
You can specify a css/js file to replace the one by default using `base_css` and `base_js` options. |
|
These options take a filename in parameter. |
|
|
|
|
|
Legend box size |
|
--------------- |
|
|
|
``legend_box_size`` |
|
|
|
You can change the size of the rectangle next to the legend: |
|
|
|
.. pygal-code:: |
|
|
|
chart = pygal.Line(legend_box_size=50) |
|
values = [1, 3, 43, 123, 1231, 23192] |
|
chart.x_labels = map(str, values) |
|
chart.add('log example', values) |
|
|
|
|
|
Rounded bars |
|
--------------- |
|
|
|
``rounded_bars`` |
|
|
|
You can add a round effect to bar diagrams with `rounded_bars`: |
|
|
|
.. pygal-code:: |
|
|
|
chart = pygal.Bar(rounded_bars=20) |
|
chart.add('rounded', [3, 10, 7, 2, 9, 7]) |
|
|
|
|
|
Static options |
|
-------------- |
|
|
|
``print_values, print_zeroes`` |
|
|
|
By default, when the graph is viewed using a non javascript compatible |
|
viewer or as an image, all the values are displayed on the graph. |
|
|
|
It can be disabled by setting `print_values` to `False`. |
|
|
|
``print_zeroes`` can be enabled to display static values even if equal to zero. |
|
|
|
|
|
Disable xml declaration |
|
----------------------- |
|
|
|
``disable_xml_declaration`` |
|
|
|
When you want to embed directly your SVG in your html, |
|
this option disables the xml prolog in the output. |
|
|
|
Since no encoding is declared, the result will be in unicode instead of bytes. |
