在轴上缩放值/标签

Question

具有一个具有以下值范围的数据集，

x from 0 to 100

y from 0.0 to 10.0^10

我正在使用plot函数绘制图形plot(x, y)。该图形已绘制，但带有以下警告，即将y值从整数转换为浮点数。

multiplot> set ytics in scale  1.4 border mirror ( "0" 0,  "1e+10" 10000000000,  "2e+10" 20000000000,  "3e+10" 30000000000,  "4e+10" 40000000000,  "5e+10" 50000000000,  "6e+10" 60000000000,  "7e+10" 70000000000) textcolor rgb "#262626" font ",10";
line 2: warning: integer overflow; changing to floating point

y值已经处于浮动状态，但是不确定为什么会引发此警告。是否可以在axis或ytics上设置显式格式设置（Format specifiers）？

一个类似的问题发布在here中。但是似乎这些是gnuplot命令/选项。如何在八度plot中使用相同的选项？

Answer 1

这也许就是您想要的吗？尽管将1e10编写为10000000000并不是很“用户友好”。

set xrange[0:100]
set yrange[0:1e10]

set format y "%.0f"

plot exp(x)
