VSL Plot

This is in a very early stage of development so issues are to be expected. The lack of features is the major problem right now, but these are slowly but surely going to be added. If you find any problem, please file an issue and we will try to solve it as soon as possible. Any suggestion is welcome!

vsl.plot follows the structure of Plotly's graph_objects. Check the examples folder and compare it to Plotly's Python examples for a better understanding.

Dependencies

• Python 3

Supported Graph Types

• Bar
• Heatmap
• Pie
• Scatter
• Scatter 3D
• Surface

Examples

Bar plot

module main

import vsl.plot

fn main() {
	mut plt := plot.new_plot()

	plt.add_trace(
		trace_type: .bar
		x_str: ['China', 'India', 'USA', 'Indonesia', 'Pakistan']
		y: [1411778724., 1379217184, 331989449, 271350000, 225200000]
	)
	plt.set_layout(
		title: 'Countries by population'
	)
	plt.show() or { panic(err) }
}

Output

Pie plot

module main

import vsl.plot

fn main() {
	mut plt := plot.new_plot()

	plt.add_trace(
		trace_type: .pie
		labels: ['Nitrogen', 'Oxygen', 'Argon', 'Other']
		values: [78., 21, 0.9, 0.1]
		pull: [0., 0.1, 0, 0]
		hole: 0.25
	)
	plt.set_layout(
		title: 'Gases in the atmosphere'
		width: 750
		height: 750
	)
	plt.show() or { panic(err) }
}

Output

Scatter plot

module main

import vsl.plot
import vsl.util

fn main() {
	y := [
		0.,
		1,
		3,
		1,
		0,
		-1,
		-3,
		-1,
		0,
		1,
		3,
		1,
		0,
	]
	x := util.arange(y.len).map(f64(it))

	mut plt := plot.new_plot()

	plt.add_trace(
		trace_type: .scatter
		x: x
		y: y
		mode: 'lines+markers'
		marker: {
			size: []f64{len: x.len, init: 10.}
			color: []string{len: x.len, init: '#FF0000'}
		}
		line: {
			color: '#FF0000'
		}
	)
	plt.set_layout(
		title: 'Scatter plot example'
	)
	plt.show() or { panic(err) }
}
