问题 Is it possible to draw a column bar chart with Highcharts.js, where one bar is displayed as an arrow? I have following chart $(function () { $('#container').highcharts({ chart: { type: 'column' }, title: { text: 'Title' }, xAxis: { categories: [ '2016', '2017', '2018' ] }, yAxis: [{ min: 0, title: { text: 'Header' } }, { title: { text: '' }, opposite: true }], legend: { shadow: false }, tooltip: { shared: true }, plotOptions: { column: { grouping: false, shadow: false, borderWidth: 0, } },

问题 I am working with this plot where the data and the lines are not showing properly. When it has more data and while zooming it with mouse wheel, the lines are not showing properly. I tried placing polygon box around series line thinking that the series will show up like the XYTextAnnotation , but it's not working. import java.awt.Color; import java.awt.BasicStroke; import org.jfree.chart.ChartPanel; import org.jfree.chart.JFreeChart; import org.jfree.chart.annotations.*; import org.jfree.data

问题 In a view, I can not change the orientation of the text of the labels of the X axis I tried to add a property in a theme but this does not seem to work. Do you have an idea for it to work? @{ string myTheme = "<Chart>\r\n <ChartAreas>\r\n <ChartArea Name=\"Default\" _Template_=\"All\">\r\n <AxisX TextOrientation=\"Rotated90\" Interval=\"1\" />\r\n </ChartArea>\r\n </ChartAreas>\r\n \r\n \r\n</Chart>"; var myChart = new Chart(width: 600, height: 400, theme: myTheme) .AddSeries( name: "test ",

问题 I am playing around with Google Chart to look a certain way. In this situation I have a combo chart a line and column chart. I have stumble upon a view "layout" problems How do replace the show2r legend with just some custom text? At the moment says: y = 2.032E-4 * x - 8.203 r^2 = 7.005E-3 and I want to replace it with "Trendline (Lineair) 2/ Also the legend gets a 1/2 and Arrows left and right. I like the legend to always be visible? 3/ The x axis doesn't display all dates, how can I set

问题 I need to show some sort method(for example BubbleSort) working and replacing bars to each other. I want to do it step by step. So in every element changing iteration I am also changing bar's places and use method layout() to show changes. However, changes are shown only after this sort method. I want to replace bars step by step and show that probably with some little delay(Thread.sleep(100);). Every bar in chart is associated with element in array_tmp. How can I do that? public void

问题 I've a dynamic chart, and I get into difficulties clearing the dataseries. From what I understand, the dataseries indices are cumulative. Meaning, if I copy the "chart 4" from another sheet with 12 dataseries cleanly made. The number of dataseries = 12 = ActiveSheet.ChartObjects("Chart 4").Chart.SeriesCollection.count and the indices for these series run from 1 to 12. Now if I delete one series and add one, the number of dataseries will continue to be 12, but the indices will now run from 1
