Add polar plot #8

Closed 153957 closed 9 years ago

153957 commented 10 years ago

Add polar plot options.

Extras:

Scatter plot function
Code style fixes
Set axis background color
Tutorial

Todo:

[x] Improve moving the y axis
- [x] Also move the tick marks
- [x] More flexibel do not use cm units..
- ~~Work properly when x limits are set~~
[x] Move x-ticks outside the axis, they are inside despite tick align=outside
[x] Add degree (°) sign to x axis labels
[x] Make degree sign optional, especially for y (radius) axis ticks
[x] Histogram support
[x] Allow radians as data values for x axis
- [x] Make axis tick labels range (-π, .., 0, ..., π) (replace 180° by ±π)
[x] Fix error when having multiple polarplot in a document (due to \newlength)
[x] Fix y-axis label shift, it sometimes shifts to far..?
[x] Add feature to allow manual setting of axislabels

Polar histograms!

Setting x (phi) limits does not work properly. The limits work, but the axes are messed up. Probably related to the current method used for shifting the r-axis.

~~Currently I made it so that the last bin also connects to the start point. This works well when the bins go from 0 to 360, to get a fully connected line. However, if the last bin is 270 a straight line is drawn from that value to the first bin.~~ The first and last bin are only connected if (bin_edges[-1] % 360) == (bin_edges[0] % 360)..

I'm impressed! Beautiful.

The \newlength introduced in 444b0e64678c to shift y ticks labels works well, except when multiple of these figures are included in the same document. A newlength can not be defined twice.

A similar issue is mentioned in this question: http://tex.stackexchange.com/a/184993

I tried adding \let\ytickshift\relax to to the script but then got an error that the polaraxis envoirnment was unknown (or undefined). Very strange..

The error can be seen by trying to make demo with 582e63c.

The \ytickshift problem and the inconsistent xlabel placements are fixed!
