<p>The most important changes in matplotlib 2.0 are the changes to the
default style.</p>
<p>While it is impossible to select the best default for all cases, these
are designed to work well in the most common cases.</p>
<p>A 'classic' style sheet is provided so reverting to the 1.x default

<p>In addition to changing the colors, an additional method to specify
colors was added. Previously, the default colors were the single
character short-hand notations for red, green, blue, cyan, magenta,
yellow, and black. This made them easy to type and usable in the
abbreviated style string in <code class="docutils literal notranslate"><span class="pre">plot</span></code>, however the new default colors
are only specified via hex values. To access these colors outside of
the property cycling the notation for colors <code class="docutils literal notranslate"><span class="pre">'CN'</span></code>, where <code class="docutils literal notranslate"><span class="pre">N</span></code>
takes values 0-9, was added to
denote the first 10 colors in <code class="docutils literal notranslate"><span class="pre">mpl.rcParams['axes.prop_cycle']</span></code> See

<p>The default dpi used for on-screen display was changed from 80 dpi to
100 dpi, the same as the default dpi for saving files. Due to this
change, the on-screen display is now more what-you-see-is-what-you-get
for saved files. To keep the figure the same size in terms of pixels, in
order to maintain approximately the same size on the screen, the
default figure size was reduced from 8x6 inches to 6.4x4.8 inches. As
a consequence of this the default font sizes used for the title, tick
labels, and axes labels were reduced to maintain their size relative
to the overall size of the figure. By default the dpi of the saved
image is now the dpi of the <a class="reference internal" href="../api/_as_gen/matplotlib.figure.Figure.html#matplotlib.figure.Figure" title="matplotlib.figure.Figure"><code class="xref py py-obj docutils literal notranslate"><span class="pre">Figure</span></code></a> instance being

<p>Previously, boxplots were composed of a mish-mash of styles that were, for
better for worse, inherited from Matlab. Most of the elements were blue,
but the medians were red. The fliers (outliers) were black plus-symbols
(<code class="xref py py-obj docutils literal notranslate"><span class="pre">+</span></code>) and the whiskers were dashed lines, which created ambiguity if
the (solid and black) caps were not drawn.</p>
<p>For the new defaults, everything is black except for the median and mean
lines (if drawn), which are set to the first two elements of the current
color cycle. Also, the default flier markers are now hollow circles,
which maintain the ability of the plus-symbols to overlap without
obscuring data too much.</p>

<p>Minor ticks on a log axis are now labeled when the axis view limits
span a range less than or equal to the interval between two major
ticks. See <a class="reference internal" href="../api/ticker_api.html#matplotlib.ticker.LogFormatter" title="matplotlib.ticker.LogFormatter"><code class="xref py py-obj docutils literal notranslate"><span class="pre">LogFormatter</span></code></a> for details. The
minor tick labeling is turned off when using <code class="docutils literal notranslate"><span class="pre">mpl.style.use('classic')</span></code>,
but cannot be controlled independently via <code class="docutils literal notranslate"><span class="pre">rcParams</span></code>.</p>

an offset will be used when it will save 4 or more digits. This can
