# LineAnimator¶

This example shows off some ways in which you can use the LineAnimator object to animate line plots.

```
import numpy as np
import matplotlib.pyplot as plt
from sunpy.visualization.imageanimator import LineAnimator
```

Animate a 2D cube of random data as a line plot along an axis where the x-axis drifts with time.

```
# Define some random data
data_shape0 = (10, 20)
data0 = np.random.rand(*data_shape0)
```

Define the axis that will make up the line plot

```
plot_axis0 = 1
slider_axis0 = 0
```

Define value along x axis which drift with time. To do this, define xdata to be the same shape as the data where each row/column (depending on axis to be animated) represents the x-axis values for a single frame of the animations.

```
xdata = np.tile(np.linspace(0, 100, data_shape0[plot_axis0]), (data_shape0[slider_axis0], 1))
```

Generate animation object with variable x-axis data.

```
ani = LineAnimator(data0, plot_axis_index=plot_axis0, axis_ranges=[None, xdata])
```

Show plot

```
plt.show()
```
