我有一个XY图表，x轴从0到250，步长为50。
由于我的点之间用30隔开，因此我希望在网格和轴标签中的步长为30。
我想更改我的step的ValueAxis属性，但是它是只读的。
我尝试设置"autoGridCount": false并增大"gridCount"：在12，步长为20，在13，步长为50。有人说要更改labelFrequency，但是我看不到通过增大或减小其效果。
我怎么能得到这个？

var chart = AmCharts.makeChart("chartdiv", {

"autoMargins": true,
"autoMarginOffset" : 10, //Space left from axis labels/title to the chart's outside border, if autoMargins set to true.

"minimum":0,
"maximum":240,
"gridCount": 32,
"labelFrequency" : 1.5,
"gridColor":"black", // center y axis
"gridAlpha":0.50, // grids visibily strength
"axisAlpha":0, // default axis at right hidden
},
{

希望这就是您想要的。.抱歉，上一次很着急，因此答案不清楚
