Interpolations need the `scipy python module <http://www.scipy.org/>`_.
|
||
|
|
To enable it just specify the interpolation type to:
|
||
|
|
|
||
|
|
- linear
|
||
|
|
- nearest
|
||
|
|
- zero
|
||
|
|
- slinear
|
||
|
|
- quadratic
|
||
|
|
- cubic
|
||
|
|
- krogh
|
||
|
|
- barycentric
|
||
|
|
- univariate
|
||
|
|
- or an integer representing the order of the spline interpolator
|
||
|
|
|
||
|
|
For more info see `interp1d definition on scipy <http://docs.scipy.org/doc/scipy/reference/generated/scipy.interpolate.interp1d.html#scipy.interpolate.interp1d>`_

Without interpolation:
|
||
|
|
----------------------
|
||
|
|
|
||
|
|
`interpolation`
|
||
|
|
|
||
|
|
.. pygal-code::
|
||
|
|
|
||
|
|
chart = pygal.Line()
|
||
|
|
chart.add('line', [1, 5, 17, 12, 5, 10])
|
||
|
|
|
||
|
|
With cubic interpolation:
|
||
|
|
-------------------------
|
||
|
|
|
||
|
|
`interpolation`
|
||
|
|
|
||
|
|
.. pygal-code::
|
||
|
|
|
||
|
|
chart = pygal.Line(interpolate='cubic')
|
||
|
|
chart.add('line', [1, 5, 17, 12, 5, 10])
|
||
|
|
|
||
|
|
With krogh interpolation:
|
||
|
|
-------------------------
|
||
|
|
|
||
|
|
`interpolation`
|
||
|
|
|
||
|
|
.. pygal-code::
|
||
|
|
|
||
|
|
chart = pygal.Line(interpolate='krogh')
|
||
|
|
chart.add('line', [1, 5, 17, 12, 5, 10])
|
||
|
|
|
||
|
|
|
||
|
|
Interpolation precision
|
||
|
|
-----------------------
|
||
|
|
|
||
|
|
`interpolation_precision`
|
||
|
|
|
||
|
|
You can change the resolution of the interpolation with the help of `interpolation_precision`:
|
||
|
|
|
||
|
|
|
||
|
|
.. pygal-code::
|
||
|
|
|
||
|
|
chart = pygal.Line(interpolate='krogh', interpolation_precision=15)
|
||
|
|
chart.add('line', [1, 5, 17, 12, 5, 10])
|
||
|
|
|
||
|
|
.. pygal-code::
|
||
|
|
|
||
|
|
chart = pygal.Line(interpolate='krogh', interpolation_precision=50)
|
||
|
|
chart.add('line', [1, 5, 17, 12, 5, 10])
