将Highcharts的最大Y值设置为精确的数值而不舍入 [英] Setting Highcharts maximum Y value to an exact amount without rounding

问题描述

每次我在Highcharts中设置我的最小值和最大值时，我从来没有得到具有我发送的确切最小值和最大值的图表，但总是有点接近。看起来好像Highcharts正在为坐标轴选择间隔范围，如果我的最大值不符合正确的间隔，它会被忽略或舍入。

例如

例如，如果我设置Y轴的最小值为0，最大值为3125，那么我会得到一个Y轴，从0开始，然后以500的增量上升到最大值3500，这根本不是我想要的。 p>

我可以让图表使用一个确切的最大值，还是总是以一种更奇怪的方式进行取整？

解决方案

1）将您的tickInterval设置为一个数字，它平均分配到您的最大值

2）将'endOnTick'设置为false为您的y轴，并将您的maxPadding设置为0.这会将图表max设置为您的规格，而不管最后一次打勾下降。

Every time I set my min and max values in Highcharts, I never get graphs with the exact min and max that I sent, but always something somewhat close. It seems as though Highcharts is picking a interval range for the axes and if my maximum doesn't conform to the right interval, it gets ignored or rounded off.

For example, if I set a min of 0 and a max of 3125 for a Y axis, I get a Y axis starting with 0 then going up in increments of 500 to a maximum of 3500, which is not at all what I want.

Can I get the chart to use an exact maximum or will it always round up in some wierd way?

解决方案

There are a couple of things that you can do.

1) set your tickInterval to a number that divides evenly into your max

2) set 'endOnTick' to false for your y axis, and set your maxPadding to 0. This will set the chart max to your specification, regardless of where the last tick falls.
