Highcharts

问题 I would like to ask if any of you already has experience with automatically generated plotline in case that "some condition". I have highchart connected to SQL Server from where I am reading numbers (of resistance) to yAxis and datetime for xAxis. Everything is working properly but I would like to put a plotline every time when the value of resistance is going let's say at least 30% down. So the main question is how to create a condition (in javascript/mssql/php...) which will be comparing

问题 The problem is best described in following fiddle : https://jsfiddle.net/bernhard_kern/85s2fm5a/3/. We use two series and two xAxis. xAxis: [{ type: 'datetime', min: new Date('2016/02/22').getTime(), max: new Date('2016/03/05').getTime() }, { type: 'datetime', min: new Date('2015/02/22').getTime(), max: new Date('2015/03/06').getTime() }], I want to compare yearly timseries, which have a different amount of values due to leap year (2016, 29 Feb.). Requirement: Display the equal dates below

问题 I want to select multiple sections in pie chart. And section should be unselected on clicking, if it is already selected. I found an example here. But in this case, only one section can be selected and selected ones get deselected on clicking on any other section. Similarly, I found another example [ $(function () { var chart = new Highcharts.Chart({ chart: { renderTo: 'container', type: 'pie' }, plotOptions: { series: { states: { hover: { enabled: false } }, point: { events: { click:

问题 Are there some highcharts pros out there? What i want is, that value 6 (lowest score) starts left and on the right there is the highest score (1) so the bars heading to 1 (showing the space to be mark 1) like: |------------------------(1.9) |--------------------(2.3) |----------------------------(1.4) 6..............3................1 http://jsfiddle.net/aCz2s/1/ Any help with that? 回答1: You can set reversed to yAxis too, like you did on xAxis . Like this: xAxis: { reversed: true }, yAxis: {

问题 I am looking for a javascript solution to display rankings across time. Being familiar with Highcharts I am wondering if there is a way to display rankings in a "user-friendly way", by which I mean: with the #1 ranking being at the top of the chart , and the last ranking being at the bottom . Does anyone know if this is possible? or of an alternative solution? 回答1: You can reverse the Y axis to achieve this (see ref) yAxis: { title: { text: 'Rank' }, allowDecimals: false, reversed: true, min:

问题 Is there a way to specify the stacking order of time series in Highcharts? 回答1: The only way I have found is by ordering the series as they come in. So, if I have series A, B, and C and I want it to be ordered by B, C, A then I add the series in B, C, A order such that series[0] = B, series[1] = C, and series[2] = A. This is definitely a kludge because it would be nice to just sign a stacking index instead of resorting the series import order. 回答2: You could assign an index to your series and

问题 I am creating a column chart using High Charts -- I am not able to show all the data labels for all the series in the chart. I have two series in a column chart while the first series shows all the data labels the second series do not displays few of the data labels while displaying others.

"chart": { "type": "column", "plotShadow": false, "polar": false, "renderTo": "" }, "credits": { "enabled": false },

问题 I need to display multiple pie charts that are all related to the same data. As such I want them all to be part of the same chart and implement them as individual series. This all works no problems until I tried to put labels/titles over each individual pie chart. It seems that I can only have a title over the entire group. See jsfiddle Is there any way to have the titles over each chart? See above jsfiddle for example 回答1: I encountered the same problem, and found this solution via

问题 Has anyone tried using Plotly or Highchart in R Script Visual of Power BI, when I try this in R script editor and Run: library(ggplot2) library(plotly) x <- 1:5 y <- c(1, 3, 2, 3, 1) plot_ly(x = dataset$period, y = dataset$mean, name = "spline", line = list(shape = "spline")) Error Message: No image was created. The R code did not result in creation of any visuals. Make sure your R script results in a plot to the R default device. But runs perfectly on my R desktop. Any thought? 回答1: For
