GSoC 2017: Layout Manager

Hi

I'm an electronics and telecommunications engineering student from
University Moratuwa, Sri Lanka. I am interested in the matplotlib project
Layout Manager.

I have done some work with python and am quite familiar with python and
regular libraries like numpy, scipy. I have also been involved in some
machine learning and computer vision related research at university, so I
am familiar with contraint solvers as well as most common AI related
algorithms.

I am going through the Cassowary library for now. I couldn't find the
issues on the mailing list related to this. Could you share with me the
detailed expectations of this project?

Also do let me know how else I can get involved for now.

Thank you.

With Regards
Kanchana Ranasinghe

I'd suggest looking through the geometry manager labels (
Issues · matplotlib/matplotlib · GitHub),
but hopefully a developer more familiar with layout manager tasks can chime
in.

Thanks so much. I did go through the issues. I will need to familiarize
myself with the layout manager as well. I was also going through the
categorical color project which seems interesting. Could you share
something more about the 'categorical color' project?

Sorry for being late on this, but essentially the categorical color project
is about building out support for this idea that strings can be as much
data as numbers and so you should be able to map them to colors just as you
can numerical data. The categorical project on github has an open PR where
I'm trying out one approach to tackle the problem, but there are other
approaches too. Here's an example of what I'm aiming for

Please feel free to ask questions.

Thank you very much. And extremely sorry for the delay on my side too. I
was really lost and struggling with understanding everything. I did read
through the example as well as most of your GSOC log last year. It was
really helpful in getting a good grasp on everything.

I understood the work done in axis ticks for categorical data. I also read
through the open PR (#6934
<https://github.com/matplotlib/matplotlib/pull/6934&gt;\), and #6214
<Issues · matplotlib/matplotlib · GitHub. I still couldn't
exactly understand what #6802
<Issues · matplotlib/matplotlib · GitHub; is about though. I
also went through #7383
<Issues · matplotlib/matplotlib · GitHub; and am trying to
work on that. Is this a good starting point for me? I still don't think
have a great overall idea about everything.

Also I am writing a proposal. I was thinking of going with your approach
and extending categorical support for imshow. Is this a good idea for the
project? Really sorry about all the small questions. I am somewhat new to
opensource and finding it quite difficult.

Thank you.

No problem, ask away, that's what this period of the application process is
for. 6802 and 6214 are mostly asking for the same thing, which is
basically to allow users to pass in a list of labels to scatterplot for the
coloring and have the dots colored accordingly and then autogenerate a
legend from that. I think #7383 might be a good place to start in terms of
the proposal, but that if you're still confused you should start by reading
the colormap and normalization documentation.,

I think you should work on whatever appeals to you/will make your own work
easier. Also, make sure to follow the mpl contribution guide:

Also about scalarMappables. I read through the documentation
<http://matplotlib.org/api/cm_api.html&gt; and also the code at
matplotlib.cm.ScalarMappable. Is this a wrong place I am looking at? Can
you explain a little bit about scalarMappables. I am confused about that.

though. I also went through #7383
<Issues · matplotlib/matplotlib · GitHub; and am trying
to work on that. Is this a good starting point for me? I still don't think
have a great overall idea about everything.

Also I am writing a proposal. I was thinking of going with your
approach and extending categorical support for imshow. Is this a good idea
for the project? Really sorry about all the small questions. I am somewhat
new to opensource and finding it quite difficult.

Thank you.

Sorry for being late on this, but essentially the categorical color
project is about building out support for this idea that strings can be as
much data as numbers and so you should be able to map them to colors just
as you can numerical data. The categorical project on github has an open PR
where I'm trying out one approach to tackle the problem, but there are
other approaches too. Here's an example of what I'm aiming for
Clearly Color Categories

Please feel free to ask questions.

Hi

I'm an electronics and telecommunications engineering student
from University Moratuwa, Sri Lanka. I am interested in the matplotlib
project Layout Manager.

I have done some work with python and am quite familiar with
python and regular libraries like numpy, scipy. I have also been involved
in some machine learning and computer vision related research at
university, so I am familiar with contraint solvers as well as most common
AI related algorithms.

I am going through the Cassowary library for now. I couldn't find
the issues on the mailing list related to this. Could you share with me the
detailed expectations of this project?

Also do let me know how else I can get involved for now.

Thank you.

ScalarMappables takes in an array of scalar values and returns RGBA values
relevant to each scalar. This is what I thought. Is this correct?

And by different types of scalarMappables, do you mean the different class
objects in colormaps, pyploy, etc.?

Hi

Thank you very much for the comments. Will change those.

Also about scalarMappables. I read through the documentation
<http://matplotlib.org/api/cm_api.html&gt; and also the code at
matplotlib.cm.ScalarMappable. Is this a wrong place I am looking at? Can
you explain a little bit about scalarMappables. I am confused about that.

I was really lost and struggling with understanding everything. I did
read through the example as well as most of your GSOC log last year. It was
really helpful in getting a good grasp on everything.

I understood the work done in axis ticks for categorical data. I also
read through the open PR (#6934

Kind of? I think we may be talking about the same thing from different
angles. I'm thinking about any function that takes in (and therefore
returns) a cmap & norm that can then be passed into scalerMappables to make
a colorbar. This includes stuff like imshow, matshow, pcolor, pcolormesh,
scatter, and probably others.

Hi,

Really sorry for constantly troubling you over the weekend. Another small
question about something I'm confused about. Regarding categorical data
support for the norm and cmap functions.

Currently, norm maps numerical data to [0,1] interval and cmap assigns
different colors to each point of [0,1] interval. This integrates with the
various scalarMappables to plot data. In making categorical units support,
norm will map strings to [0,1] interval and cmaps will remain the same. Is
this correct?

Thank you

Kanchana Ranasinghe

Using the unit interface, CategoricalConvertor maps strings to numbers. If
unit support can be extended to more plotting functions, then the norm can
work directly in data space (so with strings). This means users can just
use a colormap without having to explicitly set a norm. A norm then would
just be used to specify which of the data to register and which to leave
out, or the data/color mapping-I started prototyping this in one of the
PRs.
