r - qcc pareto.chart: bars are squashed - how to adjust the y axis?

Question

I've produced a pareto.chart using the QCC package in R. In the default plot, the Y axis is scaled too large & for that reason the bars are too small. Most of the plot is wasted to empty white space. I assume this is a result of the long tail (right-skew) in the data ?

How is it possible to re-scale the Y-Axis so that the bars of the chart will be taller and more prominent (and differences between the bars more visible) ?

This is my first question and I can't post images yet. Please follow the link to an illustration of the problem:

Answer 1

如果您键入help(pareto.chart)，您将看到有一个选项ylim可以指定 y 轴的限制。如果您提供一些示例数据，我可以尝试一下。

否则，请尝试包含在您的函数调用中

pareto.chart(..., ylim=c(0,10000))

看看这是否会重新调整您的 y 轴。
