`plotez` is a Python library that simplifies common matplotlib plotting tasks with an intuitive API. Create complex plots
with minimal boilerplate code.

## Features

- **Simple API**: Create complex plots with just a few lines of code
- **Error Bar Plotting**: Comprehensive error bar support with enhanced styling options
- **Error Band Plotting**: Shaded error band support via `plot_errorband` and `ErrorBandConfig`
- **Dual-Axis Support**: Easy creation of dual y-axis or dual x-axis plots
- **Multi-Panel Layouts**: Flexible subplot arrangements with automatic labeling
- **File Integration**: Direct plotting from CSV files
- **Extensive Customization**: Full control over plot appearance via parameter classes
- **Custom Exceptions**: Domain-specific exceptions for clear, catchable error handling
- **Type Safety**: Complete type hints for better IDE support and type checking (PEP 561 compliant)
- **Well Tested**: Comprehensive test suite with 80%+ coverage

## Installation

### From PyPI

```bash
pip install plotez
```

### From Source

```bash
git clone https://github.com/syedalimohsinbukhari/plotez.git
cd plotez
pip install -e .
```

### Development Installation

```bash
pip install -e ".[dev]"
```

## Quick Start

```python
import numpy as np
from plotez import plot_xy

x = np.linspace(0, 10, 100)
y = np.sin(x)
plot_xy(x, y, auto_label=True)
```

![README_E1_simple](https://raw.githubusercontent.com/syedalimohsinbukhari/plotez/refs/heads/master/examples/ex_images/README_E1_simple.png)

That's it. Three lines for a labeled plot.

## Examples

### Scientific Error Bars

```python
import numpy as np
from plotez import plot_errorbar
from plotez.backend import ErrorPlotConfig

rng = np.random.default_rng(1234)

x = np.linspace(0, 10, 20)
y = np.sin(x)
y_err = 0.2 * rng.random(size=y.shape)

ep = ErrorPlotConfig(color="darkblue", marker="o", capsize=5, ecolor="red", markerfacecolor="lime")
plot_errorbar(x, y, y_err=y_err, errorbar_config=ep, auto_label=True)
```

![README_E2_scientific_errorbars](https://raw.githubusercontent.com/syedalimohsinbukhari/plotez/refs/heads/master/examples/ex_images/README_E2_scientific_errorbars.png)

Professional error bars in a few lines of config. `ecolor` sets the error bar colour independently from the line colour.

---

### Dual Y-Axis

```python
import numpy as np
from plotez import plot_xyy

x = np.linspace(0, 10, 100)
y1 = np.sin(x)
y2 = np.exp(-x / 10)

plot_xyy(x, y1, y2,
         x_label="Time (s)", y1_label="Signal (V)", y2_label="Decay",
         data_labels=["Oscillation", "Envelope"])
```

![README_E3_dual_y_axis](https://raw.githubusercontent.com/syedalimohsinbukhari/plotez/refs/heads/master/examples/ex_images/README_E3_dual_y_axis.png)

Dual axes done right. No `ax.twinx()` gymnastics.

---

### Multi-Panel Grid

```python
import numpy as np
from plotez import n_plotter

x_data = [np.linspace(0, 10, 100) for _ in range(4)]
y_data = [np.sin(x_data[0]), np.cos(x_data[1]),
          np.tan(x_data[2] / 5), x_data[3] ** 2 / 100]

n_plotter(x_data, y_data, n_rows=2, n_cols=2, auto_label=True)
```

![README_E4_multi_panel_grid](https://raw.githubusercontent.com/syedalimohsinbukhari/plotez/refs/heads/master/examples/ex_images/README_E4_multi_panel_grid.png)

Four plots, one function call.

---

### Error Bands

Use `ErrorBandConfig` and `LinePlotConfig` for explicit, IDE-friendly configuration:

```python
import numpy as np
from plotez import plot_errorband
from plotez.backend import ErrorBandConfig, LinePlotConfig

x = np.linspace(0, 10, 50)
y = np.sin(x)
y_lower = y - 0.2
y_upper = y + 0.2

band_config = ErrorBandConfig(color="darkblue", alpha=0.25)
plot_config = LinePlotConfig(color="gold", linewidth=2, linestyle="--",
                             marker="o", markersize=5, markeredgecolor="k")

plot_errorband(x, y, y_lower, y_upper,
               data_label="Measurement", band_config=band_config, line_config=plot_config)
```

![README_E5-1_error_band](https://raw.githubusercontent.com/syedalimohsinbukhari/plotez/refs/heads/master/examples/ex_images/README_E5-1_error_band.png)

The same result using the `ebc` / `lpc` shorthand aliases — familiar matplotlib parameter names, no class imports needed:

```python
import numpy as np
from plotez import ebc, lpc, plot_errorband

x = np.linspace(0, 10, 50)
y = np.sin(x)
y_lower = y - 0.2
y_upper = y + 0.2

band_config = ebc(c="darkblue", alpha=0.25)
plot_config = lpc(c="gold", lw=2, ls="--", marker="o", ms=5, mec="k")

plot_errorband(x, y, y_lower, y_upper,
               data_label="Measurement", band_config=band_config, line_config=plot_config)
```

![README_E5-2_error_band](https://raw.githubusercontent.com/syedalimohsinbukhari/plotez/refs/heads/master/examples/ex_images/README_E5-2_error_band.png)

---

### Full Customization

```python
import numpy as np
from plotez import plot_xyy
from plotez.backend import LinePlotConfig

x = np.linspace(0, 10, 50)
y1, y2 = np.sin(x), np.cos(x)

config = LinePlotConfig(
    linestyle=["--", "-."],
    color=["crimson", "gold"],
    marker=["o", "s"],
    markersize=[8, 8],
    markeredgecolor=["black", "black"],
    _extra={"markevery": [5, 5]},
)

plot_xyy(x, y1, y2, plot_config=config, auto_label=True)
```

![README_E6_full_customization](https://raw.githubusercontent.com/syedalimohsinbukhari/plotez/refs/heads/master/examples/ex_images/README_E6_full_customization.png)

Config classes for when defaults aren't enough. Use `_extra` to pass any matplotlib parameter not covered by the dataclass fields.
