"谷歌图表在 yAxis 上一直显示负值"
[英]Google Chart keeps showing negative Values on yAxis
问题描述
I am currently working with Google Charts to visualize data to the user.
我目前正在使用 Google Charts 向用户可视化数据。 If there is no Data, the google chart automatically draws the y-Axis from -1 to 1. But in my case, -1 makes no sense, so I want it to show the empty chart from 0 to n (max value doesn't matter, I just don't want negative ones).如果没有数据，谷歌图表会自动将 y 轴从 -1 绘制到 1。但在我的情况下，-1 没有意义，所以我希望它显示从 0 到 n 的空图表（最大值不没关系，我只是不想要负面的）。 I already searched for solutions, and the most common answer is, that我已经搜索过解决方案，最常见的答案是，
viewWindow: {
min: 0
}

viewWindow: {min: 0}<\/code> works, but when using Material<\/em> charts, viewWindow: {min: 0}<\/code>有效，但在使用材料<\/em>图表时，
