Highcharts

问题 I am using the stochastic indicator with the 14, 3 day moving average. The resulting %k is correct, but the %d is not. For aapl on September 14, 2018, the stochastic fast is 58.95 and 56.3. However, the values returned by highstock is 44.8 and 56.3. The series it is linked to in my case is a candlestick chart. The data includes the time in milliseconds, the open, high, low and closing prices. Are there any special parameters I need to set to get the correct %d? Thank you. 回答1: Thank you for

问题 Using the Highstock (Highcharts) library, I'm wondering, how do I combine A) adding flags as in here (or see fig.1 ) with B) dynamically updating data, using the addPoint function (ex: series.addPoint([x, y], true, true) see here).

问题 I am working with highcharts to make a dashboard. Now I search each chart with the jquery for each function, to find which chart is wider than the window to make it responsive. So I have to define the width for each chart. If a chart is wider than the window, I want to define width = $(window).width(). with $(".dashboard").highcharts({ chart: { width: width, //320 }, }); I can select all charts, but how do I select a single chart? Thanks for helping. 回答1: I believe you are looking for .each()

问题 I have been populating a chart embed with data from a multidimensional PHP array ($result). When printing the array to JSON (using print json_encode($result, JSON_NUMERIC_CHECK);) i got the following array structure: [ { "name":"Array1", "data":[ 1, 2, 3 ] }, { "name":"Array2", "data":[ 1, 2, 3 ] } ] I used this array to populate my highcharts in the code below. This used to work just fine but after I changed the setup of my array it will now have to be reworked. $.getJSON("../data.php", {id:

问题 I have a chart that has a range selector on the upper left corner which allows the user to select from 1M, 3M, 6M, 1Y, 3Y, 5Y, All. This same chart also allows the user to input specific dates using date input boxes which are located on the top right of the chart. When the user selects a range from the rangeSelector, the date in the input boxes change to match the range selected, which is pretty default behavior. My objective: I need to save the range selection so that when the user comes

问题 In this question it's explained how to set the background to have two colours (zebra like). My need is to highlight in the chart temporal changes via setting accordingly the background colour, like this: the two blue area may identify periods where something was happening and the white one when it wasn't. On top of this I'll then add lines and other charts. Can this be done via passing Highchart with start and end date of periods to be highlighted? (an area chart workaround maybe?) 回答1: What

问题 Suppose I have two panes in my highstock, can I remove one of the panes dynamically. So if I click on a pane, I should be able to trap the event alongwith the id of the pane(yaXis) and subsequently delete the axis alongwith its series.
