highstock

问题 I have a Highstock chart with type scatter . When I use the range selector some of the series disappear cause the have no data in the current range. How can I prevent the chart from scaling to only the existing data an keep the yaxis in the initial state? 回答1: I can see only two options: set fixed min and max for yAxis in afterSetExtremes call yAxis[0].setExtremes(min, max) in setTimeout function, but you need to calculate min and max on your own. 来源： https://stackoverflow.com/questions

问题 When use Highstock we meet a performance issue when we use the line with compare. We need to add 15 line series and each series have 800 points.
