This lets users specify the spacing of the grid lines and the axis
labels, as well as when these start to fade out.
New:
* `AxisHints::new_x/new_y` (replaces `::default()`)
* `AxisHints::label_spacing`
* `Plot::grid_spacing`
This adds smooth scrolling in egui. This makes scrolling in a
`ScrollArea` using a notched mouse wheel a lot nicer.
`InputState::scroll_delta` has been replaced by
`InputState::raw_scroll_delta` and `InputState::smooth_scroll_delta`.
Added a public API in `egui_plot -> legend` to allow `hidden_items` to
be overridden in the plot legend widget. This allows convenient control
of traces' visibilities the selection of traces from the application
code.
### Example
```rust
let legend_config = if plot_selection_changed {
let hidden_items = match plot_selection {
PlotSelection::SelectAll => Vec::new(),
PlotSelection::DeselectAll => all_trace_names,
};
Legend::default()
.position(Corner::RightTop)
.hidden_items(hidden_items) // Overrides `hidden_items`
} else {
Legend::default().position(Corner::RightTop)
};
Plot::new(id)
.legend(legend_config)
.show(ui, draw_plot);
```

- Added methods to zoom the plot programmatically, to match the
previously added `translate_bounds()`.
- Added an example of how this method can be used to customize the plot
navigation.
Closes#1164.
This introduces a special `Color32::PLACEHOLDER` which, during text
painting, will be replaced with `TextShape::fallback_color`.
The fallback color is mandatory to set in all text painting. Usually
this comes from the current visual style.
This lets users color only parts of a `WidgetText` (using e.g. a
`LayoutJob` or a `Galley`), where the uncolored parts (using
`Color32::PLACEHOLDER`) will be replaced by a default widget color (e.g.
blue for a hyperlink).
For instance, you can color the `⚠️`-emoji red in a piece of text red
and leave the rest of the text uncolored. The color of the rest of the
text will then depend on wether or not you put that text in a label, a
button, or a hyperlink.
Overall this simplifies a lot of complexity in the code but comes with a
few breaking changes:
* `TextShape::new`, `Shape::galley`, and `Painter::galley` now take a
fallback color by argument
* `Shape::galley_with_color` has been deprecated (use `Shape::galley`
instead)
* `Painter::galley_with_color` has been deprecated (use
`Painter::galley` instead)
* `WidgetTextGalley` is gone (use `Arc<Galley>` instead)
* `WidgetTextJob` is gone (use `LayoutJob` instead)
* `RichText::into_text_job` has been replaced with
`RichText::into_layout_job`
* `WidgetText::into_text_job` has been replaced with
`WidgetText::into_layout_job`
Please take a look @Bromeon and @EmbersArc!
You have both contributed substantially to `egui_plot` (more than I
have).
This is me inviting you to co-maintain the `egui_plot` crate.
If you accept, you'll get a notification when someone opens a PR
touching `egui_plot`, and you can review and merge it as you see fit.
You can also merge your own egui_plot PRs without waiting on me to
review them.
These PR recently cleaned up the code around auto-bounds, but introduced
an involuntary change whereby auto-bounds would not be enabled by
default. All plots would default to being not properly centred as a
result.
- #3587
- #3586
This PR changes the default back to enabled. It also deprecates
`auto_bounds_x()` and `auto_bounds_y()`, which could only enable
auto-bounds (which is not very useful as auto-bounds were, and now are
again, enabled by default). A new `auto_bounds()` API can now be sued to
disable auto-bounds if needed.
Fixes#3712
Fixes https://github.com/rerun-io/rerun/issues/4503
Part 1 of 2 of adding a better API for egui_plot's auto-bounds feature.
In this PR:
- change the `Plot` builder struct field to `default_auto_bounds` (was
`auto_bounds`)
- change the `Plot` state field to `auto_bounds` (was `bounds_modified`)
- minor improvements to `Vec2b`
Thanks to `impl From<bool> for Vec2b` one can now shorten some builder
calls, like:
Previous:
```rust
egui::ScrollArea::vertical()
.auto_shrink([false; 2])
```
New:
```rust
egui::ScrollArea::vertical()
.auto_shrink(false)
```
