charts

问题 I copied this code from Google Line Chart reference and made some small changes: function drawChart() { var data = new google.visualization.DataTable(); data.addColumn('number', 'Dag'); data.addColumn('number', 'Målvikt'); data.addColumn('number', 'Uppmätt vikt'); data.addRows([ [1, 37.8, 55.0], [2, null, 69.5], [3, null, 57], [4, null, 18.8], [5, null, 17.6], [6, null, 13.6], [7, null, 12.3], [8, null, 29.2], [9, null, 42.9], [10, null, 30.9], [11, null, 7.9], [12, null, 8.4], [13, null, 6.3

问题 I am making a line graph (chart) in Excel with several data series being plotted onto the same chart. I need to create a macro/VBA solution that can turn the visibilty of these series on/off via the pressing of a button (or tick box etc) Similar to this picture (manually done through the excel menu system) I have tried to look through all the member vars/methods on https://msdn.microsoft.com/EN-US/library/office/ff837379.aspx but haven't had much luck. I have tried playing around with bits

问题 I need to customize a look and feel of standard Flex LineChart with LineSeries. I cannot figure out how to change default circles drawn when the mouse pointer is over a data point. 回答1: If you want to remove those circles, set property showDataTipTargets of chart to false .

OR Extend your LineChart and override positionAllDataTips method, which is defined in ChartBase class. Here

问题 I'd like to know how you convert these data series Data, Time, and Price to OHLC or Open, High, Low, Close. I am working on a bitcoin project and would like to see these data as a candlestick chart.

问题 I have a form in Access 2007 with a Stacked Bar Chart Object that is dynamically generated depending on the current date and outputs a PDF of the chart. Everything generates and works fine, but what is happening is data labels are being applied even for series with a Null or 0 value. This leads to a mess of text in various places. I'm looking for a way via VBA to remove any labels that belong to a series with no values. I've tried ruling out null values from the SQL query and also setting the

问题 I've created a timeline viz using Google Charts and added a dashboard with a chart range filter to allow people to move around and even zoom in so as to see certain entries more clearly. While it mostly works, sometimes it throws a "participants failed to draw" error. I've looked up other responses for this type of error but couldn't find anything that worked. See a sampling below: https://groups.google.com/forum/#!topic/google-visualization-api/AFfEjG6lG7k Google Chart with slicer returns:

问题 I have recorded a macro to create a pivot table and subsequent chart in VBA. It works like a charm, just not at all how I need it to. The problem is that I want to be able to run the code and have it create a table on a sheet that doesn't already exist. Basically I will run this from a button on a menu, and it should create the the table and chart on a new page. Without further adieu: Sub Macro13() ' Macro13 Macro ActiveWorkbook.PivotCaches.Create(SourceType:=xlDatabase, SourceData:= _ "Main

问题 This should be simple. How can I assign my own colors to the bars in Google Gantt Charts? The gantt is ignoring my colors and automatically assigning blue, red and yellow colors (in that order) to the bars and I can't seem to figure out the problem. Can someone please point out if I am missing something here or is it not supported at all at this time?
