All I wanted was to hide the category labels for every other bar in my bar chart. It does that automatically when it gets resized, and it had been annoyingly irregularly hiding some of my labels already. Is there an option for the threshold at which that happens, or to change the manner in which it chooses which ones to hide? No. Is there a list of Labels for the ticks that I can access and manually edit? No. I'll just set every other x value to the empy string, then. JavaFX takes it upon itself to sum the y values of all bars with matching x values and combine them into one bar. I finally had to just make the chart smaller to trigger the automatic reformatting. Lord Ruler, I hate this.
Map-Projections
A class to create custom maps of the Earth's surface. There are thousands of combinations of color-schemes, projections, and aspects. Includes Mercator, Gall-Peters, Orthographic, Peirce Quincuncial, and More!
Installation
If you are a fancy Windows user, I recommend the convenient fancy Windows binaries. Double-click to install them and then keep pressing buttons until something good happens. If you see a map, you're in the right place.
If you are not on Windows or are otherwise not fancy enough to deserve such executables, simply double-click on the .jar files in the main directory and, if you have Java installed (10/10 would recommend), it should just run without any set-up.
You could also compile and run the source code, but if you do, there are a few dependencies. The Java dependencies can be obtained as .jar files:
- Apache Commons Mathematics Library (you can just download and unzip the whole thing)
- Java Tools for Experimental Mathematics "ellipticFunctions" package (you only need "ellipticFunctions.jar" and "mfc.jar")
If you want to use the Python, you'll need a couple of packages from PyPI. Just install Python 3 and pip, and then call the following from a command line (or use Anaconda or something, I don't know. Up to you).
pip3 install numpy pyshp
generate_coastlines.py also takes input data from naturalearthdata.com, which should be placed in src\\zupplemental\\data\\.
Usage
There are three executable Java files, three runnable Java scripts, and four runnable Python scripts. These are, in order:
MapDesignerRaster.jar– The original program. Create custom oblique raster images of the Earth's surface using a variety of algorithms called projections.MapDesignerVector.jar– The same idea, but working in vector images instead in case you want to cut a vinyl sticker or something.MapAnalyzer.jar– See graphs and figures quantifying the amount of scale and angular distortion present in each map projection.MapPlotter.java– Plot a large group of map projections by the amount of distortion they produce.MapOptimizer.java– Run gradient descent on parametric projections to minimize their distortion.MapExplainer.java– Generate an HTML blurb outlining and displaying every map projection.generate_coastlines.py– Generate an SVG string outlining the continents, islands, and major lakes of the world, to be used as vector input.generate_graticule.py– Generate an SVG string displaying a map graticule, to be used as vector input.generate_indicatrices.py– Generate an SVG string outlining an array of Tissot's indiatrices of distortion, to be used as vector input.generate_orthodromes.py– Generate a mesh of orthodromes in an Equirectangular projection, to be used as vector input.
The executable applications all have similar layouts that let you select an input equirectangular map, a projection, an aspect (where the North Pole is situated with respect to the projection), and parameters if applicable. Go crazy! There are a practically unlimited number of combinations.
The runnable scripts just kind of work on their own. Those ones aren't really meant for mass consumption.
Wherefore?
I'll write a little blurb here later.
