Hi community,

I want the plot axes tick to be formatted for example from ‘200’ to ‘20’. My code is:

```
dx, dz = 100, 100
x = np.arange(0, 60000, dx)
z = np.arange(0, 30000, dz)
[zz, xx]= np.meshgrid(z, x, indexing='ij')
vel = 1000 + 0.032 * zz
fig = px.imshow(vel, labels=dict(x="x[km]", y="z[km]", color="Velocity (m/s)"),
color_continuous_scale='RdBu',
)
fig.update_layout(xaxis_title='x [km]', yaxis_title='z [km]', title='Raytrace')
```

The result plot is:

I want the plot axes to have a zero less. For example: the y-axis ticks be [0, 5, 10, 15, …] instead of [[0, 50, 100, 150, …]]

If anyone can help me out here, I’ll be very greatful.

Thanks
