Added a basic scatterplot for Magick backend by alishdipani · Pull Request #45 · SciRuby/rubyplot (original) (raw)

I Passed the rspec test for scatterplot for Magick backend and set up basic functions for Magick backend.
I modified the Magick backend so that it can:

• Draw x and y axis
• Draw markers
• Draw text with rotation and size
• Plot a rudimentary scatter plot

Since, GR and Magick backend uses different units for sizes, for now I have multiplied the transform function with a hard-coded value 10. I will find a suitable factor to multiply for a normalized scale for all backends. Also, no ticks are implemented in the x and y axis, I will add ticks in future.

Currently the implemented scatterplot looks like this:

Please review my changes.
