[RUBYPLOT-GSOC][DAILY][9 July] Show

Planned progress
Implement show function for GR

Progress

Implemented a basic show function for GR backend

Problems

If after calling show on a figure, a plot is added to a subplot and then write is called then the figure is not as expected. This happens for both the backends(similar incorrect figure is drawn)
the device argument is always kept as a file, which indicates saving the figure. Another option is window which is for displaying the figure. This argument can be removed, I will look into this soon.

Plans

solve the bug for consecutive show and write calling
complete the blogs
Create a list of plots
implement ticks

I have booked my visa appointment and I need to travel to Bombay for it and hence I will not be able to work on 11th, 12th and 13th. I will cover for this by working extra after returning.

v0dro · July 12, 2019, 1:11am

Did you try using a variable to indicate change of state as we had discussed over the call?

AlishDipani · July 12, 2019, 6:11am

Yes, I did try it but it had some issues related to calling the init_output_device and stop_output_device functions. I will explain the issues in more detail in today’s call.

AlishDipani · July 13, 2019, 12:58am

I couldn’t work on 10th and 11th July due to my visa application and appointment.

[RUBYPLOT-GSOC][DAILY][12 July] Show

Planned progress
Documentation for show function

Progress

Had the weekly meeting with @v0dro
Improved the show function
Tested with different combinations of the show and write and changing the plots in between

Problems

Suppose I call the write/show function and then add a plot in a subplot without initializing, it doesn’t work. But if it is initialized again, it works. So, it is necessary to initialize again after calling the write/show function.
The same thing happens with matplotlib, initialization is necessary. @v0dro
GR backend does not wait at the show function, suppose I call it two times, it shows the first time for a very short amount of time and then the second one for longer, is there any way to stop it at a show function and allow the user to keep it displaying for however long the user wants and then when a command is given then the code is executed further, @v0dro could you help me with this?

Meeting summary
Summary and To-do list:

Discussed optimizing the show function without having to save the is_initialized state variable
Discussed the device argument

Plans

complete the blogs
Create a list of plots
implement ticks

[RUBYPLOT-GSOC][DAILY][13 July] Plot

Planned progress
Working on the plot function

Progress

Looked into the plot function frontend
Corrected the tests for plot function, changed the unit of the input of sin and cosine from radians to degrees

Problems

The backend of the plot function uses Line2D(draw_lines) and draw_markers which are already implemented for Magick except for the line types and some marker types.
The plot function currently either plots lines or markers, but ideally, it should do both (if specified)
For the format of fmt argument, the string format should be decided, options are keeping it short like matplotlib or having full strings
There should be different options for marker_fill_color and marker_border_color and line colour
Magick backend can not plot a figure having size 400 cms

Plans

Complete the blogs
Create a list of plots
Implement remaining marker and line types
Work on Plot
Implement ticks

v0dro · July 15, 2019, 1:26am

Yes. Use initialization for now.

Hmmm I’m not too familiar with this part of the GR backend. However I do remember that Pranav had tried to do something similar with GR. Here’s the script that he made: https://github.com/pgtgrly/GRruby-extension/blob/master/examples/GRFramework/Example.rb#L54

I haven’t used this script in a long time but as far as I remember, it does work.

Yes. This should depend on the format string provided by the user.

I’d prefer both. Ruby symbols with full names or strings with shortcuts like in Python.

Just throw an error.

Also, finish the blogs faster.

AlishDipani · July 16, 2019, 1:15am

sure

gets doesn’t work, it waits for some time (I think this is GR default) and then gives this error:
Failures:

Rubyplot::Axes b: #Rubyplot::Backend::GRWrapper:0x00005572753e6150. #plot! plots a simple plot with plus marker of green color
Failure/Error: hold = gets

Errno::ENOENT:

I will make the necessary changes.

I’ll figure a way for this

okay

Yes, they’ll be done by Wednesday EOD

I was not able to work yesterday (16 July) as I had to make arrangements for my visa appointment (I have been called again for it). I will be having my visa appointment tomorrow(18 July) and hence won’t be able to work today and tomorrow due to traveling. However, I will try to complete the blogs during my travel.
Sorry for the inconvenience @v0dro

@v0dro Some of the marker types of matplotlib differ from Rubyplot and hence these are the characters assigned for each marker type, colour and line type:

COLOR_TYPES_FMT = {
          'b' => :blue,
          'g' => :green,
          'r' => :red,

          'm' => :magenta,
          'y' => :yellow,
          'k' => :black,
          'w' => :white
    }.freeze

    MARKER_TYPES_FMT = {
      '.' => :dot,
      ',' => :omark,
      'o' => :circle,
      'v' => :traingle_down,
      '^' => :traingle_up,
      '<' => :solid_tri_left,
      '>' => :solid_tri_right,
      '1' => :solid_triangle_down,
      '2' => :solid_triangle_up,
      '3' => :solid_tri_left,
      '4' => :solid_tri_right,
      's' => :square,
      'p' => :pentagon,
      '*' => :star,
      'h' => :hexagon,

    LINE_TYPES_FMT ={
