Python, Matplotlib, subplot: How to set the axis range?

I would like to specify the scale of the x-axis for my scatter plot similar to excel.

For example, I feed in the x axis values as follows:

```
x_values = [10, 20, 30, 40, 50, 60, 70, 80, 90, 100]
```

However, only the numbers with an even 1st digit appear.

Is there a way to make it such that all numbers appear on the x-axis?

Thanks,

You need `matplotlib.pyplot.xticks`

. In your example:

```
xticks(x_values)
```

Prepend the function call with the module name, depending on your imports.

For instance, in `ipython --pylab`

I enter:

```
In [1]: x_values = [10, 20, 30, 40, 50, 60, 70, 80, 90, 100]
In [2]: scatter(x_values, x_values)
Out[2]: <matplotlib.collections.PathCollection at 0x39686d0>
In [3]: xticks(x_values)
```

and get

Note that this leaves some space at the right, because initially the ticks were up to 120 at every 20. To have it at every 10 without knowing the maximum, you can make two calls to `xticks`

:

```
xticks(range(0, int(xticks()[0][-1])+1, 10))
```
