# implot-rs
|
|
|
|
Rust bindings for [ImPlot](https://github.com/epezent/implot), built by running
|
|
[bindgen](https://github.com/rust-lang/rust-bindgen) on [cimplot](https://github.com/cimgui/cimplot).
|
|
|
|
The bindings are currently based on ImPlot version 0.8-WIP (see
|
|
[implot-sys/third-party](implot-sys/third-party) for the exact commit currently pointed to).
|
|
The status section below provides detailed information on implementation status.
|
|
|
|
[](https://docs.rs/implot/)
|
|
|
|
|
|
**Important note:** As long as the code is pre-1.0 release, the API is expected to have
|
|
breaking changes between minor versions. Patch versions should be backwards compatible.
|
|
After 1.0, semver will be followed more properly.
|
|
|
|
|
|
|
|
## Requirements
|
|
imgui-rs requires minimum Rust version 1.40, so this project does as well by extension.
|
|
The sys crate compiles implot, so a C++ compiler will also be required.
|
|
|
|
## Examples
|
|
Examples are being built in the `implot-examples` crate in this repo. To try them out,
|
|
clone the repo, change into the `implot-examples` directory and try for example
|
|
```
|
|
cargo run --example line_plots
|
|
```
|
|
|
|
## Documentation
|
|
For released versions, see
|
|
[](https://docs.rs/implot/).
|
|
Make sure you are looking at the right release, since the API is still changing.
|
|
For the master branch, can build it yourself however by cloning this repo and then doing
|
|
```
|
|
cargo doc --open
|
|
```
|
|
An effort is made to document everything as it is being added. Feel free to open an issue
|
|
if documentation is unclear or lacking.
|
|
|
|
|
|
## Implementation status
|
|
Currently a work in progress, coverage of the C++ API is increased steadily. The author
|
|
is open to collaboration, if you'd like to help, feel free to reach out via a Github issue.
|
|
|
|
At this point, raw bindings are working in implot-sys, and more idiomatic interfaces
|
|
for plot creation as well a subset of the functionality for plots are implemented.
|
|
|
|
While the raw bindings have versions of most functions for different data types such as
|
|
32-bit or 64-bit floats and various integers, the higher-level bindings are currently only
|
|
created for 64-bit floats.

# Developer documentation

|
## Design approach
|
|
This repo tries to follow the approaches and style used in `imgui-rs` somewhat closely,
|
|
because implot is to be used within imgui programs, and hence keeping the interfaces
|
|
and design philosophies close should make it easier to do that.
|
|
|
|
If you spot any design inconsistencies or paper cuts, feel free to open an issue.
