问题 I have an excel graph that I want to create in R. I tried recreating it with some dummy data a<-rnorm(12) a_ts<-ts(a, start=c(2015, 1), frequency=12) a_time<-time(a_ts) a_series<-ts.union(ret=a_ts, date=a_time) a_series_df<-as.data.frame(a_series) ggplot() + geom_rect(data=data.frame(xmin=decimal_date(as.Date(c("2015-01-01"))), xmax=decimal_date(as.Date(c("2015-05-31"))), ymin=-Inf, ymax=Inf), aes(xmin=xmin,xmax=xmax,ymin=ymin,ymax=ymax), fill="pink", alpha=0.5) + geom_line(data = a_series_df

问题 I have implemented a time series chart in my flutter app which displays energy data over time: final List<charts.Series<TimeSeriesEnergy, DateTime>> seriesList = [ new charts.Series<TimeSeriesEnergy, DateTime>( id: 'Energy', colorFn: (_, __) => charts.MaterialPalette.blue.shadeDefault, domainFn: (TimeSeriesEnergy p, _) => p.time, measureFn: (TimeSeriesEnergy p, _) => p.energy, data: data, ) ]; final bool animate = true; var chart = new charts.TimeSeriesChart<TimeSeriesEnergy>( seriesList,

问题 I want to update a line chart in chart js with two data sets. I've somehow managed to empty the chart and then able to fill in one of the data set. but unable to make both data sets working. here's the code. ajaxRequest( { url: 'reports/updateChart/?filter=true', method: 'post', data: data }, function (response) { /*refresh the tables with the new data sets*/ removeData(myChart); let label = [1, 234, 234, 234, 234, 234, 234, 34, 234, 23, 23, 41, 3, 2, 4]; let data = [234, 234, 5, 23, 34, 234,

问题 On page jqPlot there is an example of dragging data point on jqPlot chart. How can I submit (e.g. with jQuery ajax) to server changed values? Are changed (current) values stored somewhere in jqplot object? 回答1: The hardest thing here is knowing when the user drags a point, not getting the data afterward. I recommend you use a postDrawSeries hook like so: $(document).ready(function () { // set up plot $.jqplot.config.enablePlugins = true; s1 = [['23-May-08',1],['24-May-08',4],['25-May-08',2],[

问题 I am using MPAndroidChart in my app and i was wondering if there is a way to set a diferent color for the first bar in a dynamically moving bar chart, like this: The bars are added dynamically while the whole stack is being moved to the left as the data keeps coming, is there a way to set the color of the first bar to be a different color? thank you in advance. EDIT and Solution: here is my code for adding a new entry to the chart, it occurs dynamically every 500 millis or so. private void

问题 I was having some problem when trying to customize the hover tooltip for mixed chart using chart.js. I have a bar chart which show the total profit for certain product and a line chart to show the total quantity of that certain product. When I hover over the bar chart, I wanted the tooltip to show something like: Total profit: $ 1399.30 The price should be in two decimal format appended to the back of 'Total profit: $'. When I hover over the line chart, I wanted to show something like:

问题 I am trying to display the value of each bar and then the total value of all bars in a stacked bar chart The problem is, I get the last bar's value and the total both outside the bar. If I do not show the total, I get the value inside the bar. Using the code below the the last two annotations are outside the second bar even when the second bar is long enough to show its label. <html> <head> <base target="_top"> </head> <body> <h3>Registrations</h3> <div id="registrations_chart"></div> </body>

问题 Is it possible to hide certain lines, bars and other graphic elements from a c3js chart, without unloading or hiding data? I wish to keep that data in the tooltip but hide some graphic elements. Hover over one bar and see data for other hidden bars. I know about the hide method - chart.hide(['data2', 'data3']); - but this also deletes the data from the tooltip. My question is not discussed in the documentation it seems. A similar issue in November was not solved. I don't have any code right
