# go-plot
[](https://github.com/aldebap/go-plot/actions/workflows/go.yml)
[](https://github.com/aldebap/go-plot/actions/workflows/docker-image.yml)
A Golang library with some Gnuplot features (in progress).
For more info on Gnuplot, visit [Gnuplot](http://gnuplot.info/)
### General features already working
1. Go package to generate plots from multiple sets of points;
2. creation of plots from data files;
3. creation of plots from mathematical functions (in development);
4. graphic drivers to generate the following output formats: SVG, HTML Canvas, GIF, JPEG, PNG;
5. CLI interface to read plot files and generate the graphic output;
### GNU-Plot like commands already working
1. plot command ```set terminal [svg/canvas/gif/jpeg/png]```
2. plot command ```set output "file name"```
3. plot command ```plot "data file" using i:j with [dots/boxes/lines/linespoints/points] title "description"```
4. plot command ```plot [i:j] mathematical function```
5. plot command ```set xlabel "label"```
6. plot command ```set ylabel "label"```
### Additional features already working
1. REST API interface to receive plot commands and generate the graphic output (plot/svg endpoint);
2. REST API interface to receive plot commands and generate the graphic output (plot/canvas endpoint);
3. REST API interface to receive plot commands and generate the graphic output (plot/gif endpoint);
4. REST API interface to receive plot commands and generate the graphic output (plot/jpeg endpoint);
5. REST API interface to receive plot commands and generate the graphic output (plot/png endpoint);
6. Web interface to set plot configuration and generate dynamic plots through the canvas endpoint;
7. Dockerfile to serve Web interface and the REST API interface from a single container;
### Quick start
To simply run the latest version from Github's package, type the following on bash or Powershell:
```sh
docker run -d -p 8080:8080 ghcr.io/aldebap/go-plot
```
Then use your favorite browser to go to the following URI: ```localhost:8080/plot```
### Plot file samples
```gnuplot
set terminal svg
set output "output.svg"
plot "data" using 1:2 with boxes
```
```gnuplot
set terminal svg
set output "output.svg"
plot "data" using 1:2 with lines,
"data" using 1:3
```
```gnuplot
set terminal svg
set output "output.svg"
plot [-4:+4] x * x - 3 * x + 2
```
```gnuplot
set terminal svg
set output "output.svg"
plot [0:6.283184] sin(x)
```
