`foamgraph` was originally developed as part of the online analysis framework
[EXtra-foam](https://github.com/European-XFEL/EXtra-foam.git)
to provide fast display (10 Hz) and interactive data analysis for data-intensive
photon science experiments at the state-of-art free-electron laser (FEL) facility -
European XFEL. It was originally implemented on top of the famous Python graphics
and GUI library [PyQtGraph](https://github.com/pyqtgraph/pyqtgraph). The following
features made `foamgraph` stand out:
- The widgets are dedicated for photon science experiments.
- The performance has been significantly improved.
As of now, `foamgraph` has almost evolved into its own implementation completely.
It's time to decide the direction for future development. Since there are already
many excellent GUI libraries around, `foamgraph` should and will do something different.

## Getting started
Imaging you have a data producer which streams data continuously and you would like
to build a GUI to visualize the data and perform interactive analysis while the data
is updating. Eventually, what you need is something shown in the code snippet below:
a consumer consumers the data generated by the producer and then passes the data to
the GUI.
```py
gui = PlotGalleryWindow()
consumer = Consumer(gui.queue) # the queue is used to store data streams
gui.start()
consumer.start()
```
The class `PlotGalleryWindow` can be conveniently implemented as follows:
```py
class PlotGalleryWindow(LiveWindow):
def __init__(self):
super().__init__("Plot gallery")
# define your plots
self._plots = [
ShadedPlot(parent=self),
ScatterPlot(parent=self),
BarPlot(parent=self),
ErrorbarPlot(parent=self),
MultiLinePlot(parent=self),
DoubleYPlot(parent=self),
LinePlotWithAnnotation(parent=self),
CandlestickPlot(parent=self),
StemPlot(parent=self)
]
# init your GUI layout and Qt signal-slot connection
self.init()
```
For more details of the above use case, please check [here](examples/plot_gallery.py).
In `foamgraph`, every plot widget should inherit from `GraphView`. The following code snippet
shows how to create a double-y plot with a title, axis labels and a legend:
```py
from foamgraph import FColor, GraphView
class DoubleYPlot(GraphView):
def __init__(self, *, parent=None):
super().__init__(parent=parent)
self.setTitle('Double-y plot')
self.setXYLabels("x (arb. u.)", "y (arb. u.)", y2="y2 (arg. u.)")
self._plot = self.addCurvePlot(label="Data", pen=FColor.mkPen('w'))
self._plot2 = self.addBarPlot(
label="Count", y2=True, brush=FColor.mkBrush('i', alpha=150))
self.addLegend()
def updateF(self, data):
"""Override."""
self._plot.setData(data['x'], data['y'])
self._plot2.setData(data['x'], data['y2'])
```
## Examples
* Open a terminal and start the producer:
```sh
python examples/producer.py
```
* Open another terminal and start the plot gallery example
```sh
python examples/plot_gallery.py
```

* Open another terminal and start the image analysis example
```sh
python examples/image_analysis.py
```

## Benchmarks
The benchmark was performed on a Apple M1 Pro 16GB with the GUI geometry of 800 x 600.
