Python matplotlib - 设置 x 轴比例 [英] Python matplotlib - setting x-axis scale

问题描述

我有这张图表显示以下内容:

I have this graph displaying the following:

plt.plot(valueX, scoreList)
plt.xlabel("Score number") # Text for X-Axis
plt.ylabel("Score") # Text for Y-Axis
plt.title("Scores for the topic "+progressDisplay.topicName)
plt.show()

valueX = [1, 2, 3, 4] 和scoreList = [5，0，0，2]

valueX = [1, 2, 3, 4] and scoreList = [5, 0, 0, 2]

无论scoreList"中的值是什么，我都希望比例以 1 为单位递增.目前让我的 x 轴在 0.5 秒而不是 1 秒内上升.

I want the scale to go up in 1's, no matter what values are in 'scoreList'. Currently get my x-axis going up in .5 instead of 1s.

如何设置使其仅在 1 中上升?

How do I set it so it goes up only in 1?

推荐答案

只需自行设置xticks.

Just set the xticks yourself.

plt.xticks([1,2,3,4])

或

plt.xticks(valueX)

由于范围函数恰好适用于整数，因此您可以改用它:

Since the range functions happens to work with integers you could use that instead:

plt.xticks(range(1, 5))

或者更具动态性并根据数据进行计算:

Or be even more dynamic and calculate it from the data:

plt.xticks(range(min(valueX), max(valueX)+1))
