Highcharts

问题 I want to drilldown to multiple series. How do I change the x axis categories after drilldown and still maintain my series? hc <- highchart() %>% hc_chart(type = "column") %>% hc_title(text = "Job Ratio") %>% hc_xAxis(categories = c("Job A", "Job B")) %>% hc_plotOptions(series = list(stacking = "normal")) %>% hc_yAxis(max = 100) %>% hc_add_series(name = "Completed", data = list(list(y = 40, drilldown = "job-a"), list(y = 35, drilldown = "job-a"))) %>% hc_add_series(name = "No progress", data

问题 I Am trying to do a heat map with a time line in the xAxis, and be able to display a cell in one interval, from one date, to another. This is what I would like to achieve with highcharts: http://s4.postimg.org/t5hte4xe5/image.png In a heat map the cells receive this data: [row, column, value]. So I have tried 3 options to achieve this: 1.- Have as data [row, date (as a date object), value] --> Highcharts error #19 (I guess its too many ticks to an axis, but I have got a tickInterval) 2.- Have

问题 I am currently successfully plotting wind speed and wind direction using a standard line graph for wind speed and a scatter plot for wind direction. The current windSpeed and windDirection DOM objects look like this: windDirection = "[202,229,218,208,230]"; windSpeed = "[9,13.4,12,9.7,6.6]"; In reality both those variables hold hundreds, if not thousands, of data points. Each windDirection data point corresponds to the windSpeed data point at the same location, and there are an equal number

问题 I am struggling in adding one level drilldown in my grouped column chart made using highcharter. To explain, I am taking using the "vaccines" dataset available in highcharter library : My code (similar) that creates the grouped column chart : library (highcharter) library(dplyr) df <- na.omit(vaccines[vaccines$year %in% c("1928", "1929"),]) df <- ddply(df, c("state", "year"), summarise, count = sum(count)) hc <- hchart(df, type = "column", hcaes(x = state, y = count, group = year)) %>% hc

问题 It is necessary to automaticly and dynamicly change (update) the height of highcharts's charts depending on the amount rows (example, for horizontal bars) on it. The height of one element (example, horizontal bar) is constant (for example, 20px). The height of charts with X elements set automaticly (~ 20px * X). 回答1: You can do this with a little pre-setup. Set variables for: the top and bottom margins the point and group padding the width of the points the number of data points in your data

问题 I need to create highcharts series dynamically...So I used addSeries,But I am gettng an extra legend. If you have any other methods pls let me know...

问题 I would to create different venn diagram like that http://www.biomedcentral.com/1471-2105/12/35/figure/F1 and use Highchart library (because there is a good exporting option). I found this example but i can't make the ellipses when i have 4 datasets. I think it's at "Maker" level parameters that it's possible to do it. But there is maybe another solution. Please can you give me few leads? var chart = new Highcharts.Chart({ chart: { renderTo:'container', type:'scatter' }, title:{ text:'Chart
