Does anyone know what library is used in the iPhone application Roambi to draw charts? http://www.roambi.com/ 回答1: That looks like it uses the excellent Core Plot Framework. 回答2: I think it's not Core Plot. There are some charts in the app that don't conform to Core Plot. Maybe Roambi has started from Core Plot

问题 If I do the following command data(mtcars) ggplot(data=mtcars, aes(cyl))+ geom_bar(aes(fill=as.factor(gear), y = (..count..)/sum(..count..)), position="dodge") + scale_y_continuous(labels=percent) I will get However, what I really want to do is have each of the gear levels add up to 100%. So, gear is the subgroup I am looking at, and I want to know the distribution within each group. I don't want to use facets and I don't want to melt the data either. Is there a way to do this? 回答1: First of

问题 Despite setting the labelRotation property to 90 in this column chart, the axis labels are horizontal.

问题 For a web application I'm working on, I need some pretty powerful graphing capabilities. I'm looking at using Google Charts for my needs.

Preferably in PHP. EDIT: Doesn't only have to be Google Charts. I'm looking for something that can

问题 We have a requirement to display charts in an ASP.NET MVC app but the people using the app will need to be able to print the charts to paper and also save them as an image for use in presentations. They need to be high quality for the print/present versions and it seems to me that the web based charting tools are just that - optimised for web. The co i work for have historically used fusion charts but getting the quality out of that has eluded them. If we have to build a whole separate "out

问题 I want to synchronize pan and zoom on multiple charts. I'm been using Chart.js with chartjs-plugin-zoom. charjs-plugin-zoom calls an event with the onZoom callback function. So, the values ​​at both ends of the X axis are obtained in this way with the callback function. onZoom: function () { var minVal = myChartA.getDatasetMeta(0).dataset._scale.chart.scales['x-axis-0']._table[0].time; var maxVal = myChartA.getDatasetMeta(0).dataset._scale.chart.scales['x-axis-0']._table[1].time; leftEnd =

问题 I have a query that gives me the daily status of an item based on desired date range (parameters). This status will vary and can repeat. For example, it can chronologically be: Operational, Repair, Inspection, Operational, Inspection. As you can see Operational & Inspection are represented twice but at different times. While this is true, I cannot seem to get this represented graphically in a Range Bar Chart because it will only display one instance of each status (as shown in the picture).
