Hi,

I have two questions regarding the kendo stock chart:

1. I need to retrieve a list of the currently displayed data points (not the whole data set of the series) in the events zoomEnd, dragEnd and selectEnd in order to perform some normalization. How can this be done?

2. For the same events, how do I get the min and max of the currently displayed range of the x axis?

Thanks.

Hello Raphael,

Straight to your questions: 
  1. I am afraid this is not supported out of the box in Kendo UI StockChart. As a possible workaround I can suggest to create a separate DataSource for the Navigator, filter it and in the events (zoomEnd, dragEnd or selectEnd) use the DataSource's view() method. For your convenience I prepared a simple HTML page which demonstrates this approach in action; 
  2. You can get the min and max of the current range via chart.options. For example: 
    var stockChart =  $("#stock-chart").data("kendoStockChart");
    stockChart.options.categoryAxis[0].min;
    stockChart.options.categoryAxis[0].max;

I hope this information helps.

Kind regards,
