charts

问题 I am writing a C# desktop application that requires a graphical representation (XoY) of some values (Y - value, X - (in) time). chart1.Series[0].Points.AddXY(time, new Random().Next(-325, 531)); //this operation occurs at a set interval The operation does its job, adding up values; however, in time the chart has the tendency to "squeeze" itself which makes interpreting it a much harder task. I want to make the graphic generate a better output, despite the number of points. Notes I consider

问题 I'm using Chart web helper in ASP.Net MVC 3. I have seen a range of shiny images online showing capabilities of this API, but there is hardly any documentation on how to style the charts. For example, I need to display labels outside of the chart, I'd like to specify percentage, rather than decimal values, etc. There is a webforms project for download: http://weblogs.asp.net/scottgu/archive/2010/02/07/built-in-charting-controls-vs-2010-and-net-4-series.aspx and very simple class documentation

问题 How can I display the values of X-Axis and Y-Axis when the mouse is moved anywhere within the chart area (like the picture)? The HitTest method can not be applied for moving or it can only be applied for clicking on the chart? Please help me. Thanks in advance. The tooltip shows data outside the real area data drawn 回答1: Actually the Hittest method works just fine in a MouseMove ; its problem is that it will only give a hit when you are actually over a DataPoint . The Values on the Axes can

问题 I have a jqplot pie chart with a legend and I would like to get the legend text to appear as a tooltip when the mouse hovers on the pies. I'm not sure how to do that. Does anyone have any experience doing similar? example code: $(document).ready(function(){ var data = [['Heavy Industry', 12],['Retail', 9], ['Light Industry', 14],['Out of home', 16],['Commuting', 7], ['Orientation', 9]]; var plot1 = jQuery.jqplot ('chart1', [data], { seriesDefaults: { renderer: jQuery.jqplot.PieRenderer,

问题 I'm using Google Chart in my application with the following code (JSFiddle): google.load('visualization', '1', {packages: ['corechart']}); google.setOnLoadCallback(drawChart); function drawChart() { var data = new google.visualization.DataTable(); data.addColumn('date', 'date'); data.addColumn('number', 'view'); data.addRows([ [new Date('2015-08-01'), 5], [new Date('2015-08-02'), 7], [new Date('2015-08-03'), 2], [new Date('2015-08-04'), 16], [new Date('2015-08-05'), 3], [new Date('2015-08-06'

问题 My "Chart data range" is ='sheet1'!$A$1:$Z$10 . I'd like to make a VBA macro (or if anybody knows a formula I can use, but I couldn't figure one out) to increase the ending column of the range for chart1 by 1 every time I run the macro. So essentially: chart1.endCol = chart1.endCol + 1 What is the syntax for this using ActiveChart or is there a better way? 回答1: Assuming that you want to expand the range (by adding one extra column) to add one more observation for each series in you diagram

问题 I have a simple 1-series bar chart where each bar has a nominal value. I can plot this fine with the data labels and axis representing the value for each bar but I'd like to have the data label and axis show the percentage of the total of the series while the nominal value is shown in a tooltip on hover (thus I don't want to convert the data to percentages prior to plotting). Here is an image showing what I'm after and where I am now: fiddle Here's what I currently have for axis labels as the

问题 I have a Highchart in my application showing car sales in each month. Given a user input value for a date, chart should show car sales in last 12 months.
