charts

问题 How can SSRS 2005 represent two chart types (i.e., bar and line) on the same chart? I am trying to create a graph that looks like the professionally crafted image below: The chart would have one series represented as bar graphs and then two other series represented as overlapping line graphs. I have the line graphs working as two independent series and I can write my SQL query to return empty values for the months of the bar graph series and empty values for the years on the two line series

问题 I am creating an Excel file with line chart. I've created chart and filled it with data but I cannot create points on my chart. Does anyone know, is there a way I could generate these points(triangles, squares, circles etc.) in a chart using apache poi? This is my code for generating current char: public static void main(String[] args) throws Exception { Workbook wb = new XSSFWorkbook(); Sheet dataSheet = wb.createSheet("linechart"); final int NUM_OF_ROWS = 10; final int NUM_OF_COLUMNS = 4;

问题 I've added a horizontal stripline to a sinusoidal type graph which doesn't have many datapoints. Is there a way to find the x-coordinate intersections? 回答1: You can either tackle it analytically, i.e. if your data are derived from a formula you can use math to solve the intersection set. Or you can us an approximation with a little help from GDI+ . As you have found using the DataPoints directly in a thinly populated set of points will not work well. But there is an interesting and simple

问题 I posed this question a few days ago but it has diverged in the comments enough that I think it's worthy of asking many of the points in the comments in a new question. I apologize for the length of this question. I hope that it isn't terribly unclear. I'm working on creating a chart using ggplot2 in a R Sweave file used to track benchmarks for software. I'm looking specifically at run times for the benchmark and either want to use % Deviation or deviation by minutes from the earliest test

问题 I'm new to JavaScript and i'm using chart.js to create some data visualizations, and i need to change the color of the entire bar for different values, the code i have so far is what follows, but i can't make it work, this isn't giving me any errors, so i don't know were to go. var dData1 = 90; ///////CARREGAR DADOS DE FACTURAÇÃO (for developer) var dData2 = 70; ///////CARREGAR DADOS DE FACTURAÇÃO (for developer) var barChartData = { labels: ["MÊS", "ANO"], datasets: [{ fillColor: "#f37c8a",

问题 I am working on the xlsx report generation, and for that I am using axlsx gem. I looking for the option to show secondary Y-axis (for 2nd series in charts) in line and bar charts. Is there any way to do so? Thanks in advance. 回答1: I'm not well versed in axlsx much less charting in general, but from what I've read on the documentation there are thee possible 'axes' to choose from. valAxis, catAxis and serAxis. If I'm to assume you want depth to your chart, use serAxis. http://rubydoc.info

问题 when using the chart helper in MVC5, how can I set properties that are hidden from the "original" Web.UI. chart control? Is the helper only a small subset or is there a way to assign it with themes? Some properties like BackImage can be set via template like shown here: similar question When should I use normal Control and when helper? this is the "classic" way in the controller: var myChartBack = new System.Web.UI.DataVisualization.Charting.Chart(); myChartBack.BackImage = "/Pics/Pic.jpg";

问题 I have created a donut chart. I want to display the tooltip always in the donut chart along with the legends. I have followed this stack overflow question. Question which explain the tooltip to be shown always I have followed the answer and created a doughnut chart and tried to show the tooltip always. it works fine, however it is not showing all the label, esp. when you have multiple data with 0 value.It just overwrite the label. my label and values are "Red" -0, "Green" -0 & "Yellow"-100

问题 I'm not yet as much into Java as I'd like to be, so I find my current task to be quite a bit challenging: A chart showing data gathered in another class. A slider whose end value is determined by the last entry of in the dataset used in the chart. The playbutton currently doesn't do anything except letting the slider tick in steps of 5 until it is paused again. My problem right now is: I am supposed to highlight one item at a time in the chart based on which value the slider currently shows.
