Python matplotlib - setting x-axis scale
提问by YusufChowdhury
I have this graph displaying the following:
我有这个图表显示以下内容：
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] and scoreList = [5, 0, 0, 2]
valueX = [1, 2, 3, 4] 和 scoreList = [5, 0, 0, 2]
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.
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 轴以 0.5 而不是 1s 上升。
How do I set it so it goes up only in 1?
我如何设置它使其仅在 1 中上升？

Just set the xticks yourself.
只需自己设置 xticks。
plt.xticks([1,2,3,4])
or
或者
plt.xticks(valueX)
Since the range functions happens to work with integers you could use that instead:
由于范围函数恰好适用于整数，因此您可以改用它：
plt.xticks(range(1, 5))
Or be even more dynamic and calculate it from the data:
或者更加动态并从数据中计算它：
plt.xticks(range(min(valueX), max(valueX)+1))

Hey it looks like you need to set the x axis scale.
嘿，看来您需要设置 x 轴比例。
Try
尝试
plt.axes.Axes.set_xscale(1, 'linear')
