This project starts from a full copy from [https://git.smarteching.com/zeni/go-chart](https://git.smarteching.com/zeni/go-chart). 28 Oct 2024.
|
||||
Package `chart` is a very simple golang native charting library that supports timeseries and continuous
|
||||
line charts.

|
||||
The v1.0 release has been tagged so things should be more or less stable, if something changes please log an issue.
|
||||
|
||||
Master should now be on the v3.x codebase, which overhauls the api significantly. Per usual, see `examples` for more information.
|
||||
Master should now be on the v2.x codebase, which brings a couple new features and better handling of basics like axes labeling etc. Per usual, see `_examples` for more information.
|
||||
|
||||
# Installation
|
||||
|
||||
To install `chart` run the following:
|
||||
|
||||
```bash
|
||||
> go get git.smarteching.com/zeni/go-chart/v2@latest
|
||||
> go get -u github.com/wcharczuk/go-chart
|
||||
```

# Code Examples
|

Actual chart configurations and examples can be found in the `./examples/` directory. They are simple CLI programs that write to `output.png` (they are also updated with `go generate`.

If folder ends in "web", has web servers, so start them with `go run main.go` then access `http://localhost:8080` to see the output.

# API Overview
|
||||
|
||||
Everything on the `chart.Chart` object has defaults that can be overriden. Whenever a developer sets a property on the chart object, it is to be assumed that value will be used instead of the default.
|
||||
Everything on the `chart.Chart` object has defaults that can be overriden. Whenever a developer sets a property on the chart object, it is to be assumed that value will be used instead of the default. One complication here
|
||||
is any object's root `chart.Style` object (i.e named `Style`) and the `Show` property specifically, if any other property is set and the `Show` property is unset, it is assumed to be it's default value of `False`.
|
||||
|
||||
The best way to see the api in action is to look at the examples in the `./_examples/` directory.
