Highcharts

问题 I am calculating the average-value of properties for each week of the year. And I want to display these information in a line chart (x-Axis is the week of year, y-Axis the average value and the different lines represent different properties). But for any given property I do not necessarily have a datapoint for each week of the year. If I do not have such a datapoint I want my line for this property to interpolate between the datapoints I have. Anyone else run into a similiar issue? 回答1:

问题 I am working with DotNet.Highcharts in Visual Studio 2010. I am creating a MVC 3 Web Application. I am able to get HighCharts working by statically assigning the data. I would like to be able to send the data from a database to HighCharts for displaying. Can I create a class to control the data and then send the class to HighCharts? If so, can anyone tell me how to do this? Also, if someone has a working project that demonstrates this and is willing to share that would be awesome. I saw

问题 I want to be able to catch the clicked event that is hooked to all the axis ticks. here is what i have done so far. http://jsfiddle.net/grVFk/5074/ If anyone knows how to do that with any of the charting plugins can kindly share. thanks 回答1: the plot isn't plain HTML. So there is no a tag. And the plot itself do not provide you with an api to catch the click event on an axis tick. What you can do is to select the axis tick manually with jQuery and add a click event: $('.highcharts-axis tspan'

问题 I would like to add some extra values to the standard Highcharts tooltip via rCharts. Example code: require(rCharts) df <- data.frame(x = c(1:5), y = c(5:1), z = c("A", "B", "C", "D", "E"), name = c("K", "L", "M", "N", "O")) h1 <- hPlot(x = "x", y = "y", data = df, type = "scatter", group = "z") This generates a tooltip with the x and y values. And the series name z as title. Now I also want the to add the name values to the tooltip. However I have no idea how this is done. 回答1: After several

问题 I am working on a chart with two axes, which are proportional, i.e., the second axis maximum is exactly 13.5% of the first axis maximum. I managed to do this with the callback functionnality of Highcharts, as @KacperMadej suggested me in this post: function (chart) { chart.yAxis[1].update({ max: chart.yAxis[0].getExtremes().max * 0.135 }); } It works great, but when I drilldown on my chart, the second axis stays fixed to its values before drilldown. I can't find a way to affect this axis

问题 I want the grid lines of highchart to appear only till 75% of the chart height and rest of the chart should not show the grid lines.
