问题 I am desperately trying to get my GoogleChart working. This code always throws an error though: function drawChart() { var data = new google.visualization.DataTable(); data.addColumn('number', 'hour'); data.addColumn('number', 'TriggerCount'); var JsonManuallyEncoded = '{1:{1:01,2:4},2:{1:03,2:4},3:{1:04,2:48},4:{1:05,2:59},5:{1:06,2:59},6:{1:07,2:87},7:{1:08,2:62},8:{1:09,2:46},9:{1:10,2:61},10:{1:11,2:71},11:{1:12,2:54},12:{1:13,2:61},13:{1:14,2:89},14:{1:15,2:58},15:{1:16,2:122},16:{1:17,2

问题 I have a basic pie chart with 3 wedges. When you click on a wedge of the pie, a tooltip will display. My intent is to have the same functionality for a keydown event. Scenario: When a pie slice has focus, a user can hit a key (ex: enter) which will display the tooltip exactly how the click event does. I figured this will require 2 steps. Make each pie wedge (.nv-slice) focusable by adding a 'tabindex = 0' attribute Add an event listener that triggers the tooltip similar to how a click event

问题 Maybe I am not understanding the area chart properly but here is an image to properly display what the problem is and what I am looking for: Can someone explain why stacking: normal display values like it does? And how to possibly fix it? I have tried stacking: null, and stacking: percent, but both do not give the desired results. EDIT: I see my error, however, I'm not sure how to fix it. I need to graph the two series in a group so that they are rendered together and not normalized. Any

When this occurs, I would like a scroll bar to be filled for the X axis, allowing the user to use the scroll bar to view such previous data. How do I go about doing this? I don't want the user to be able to drag or zoom on the chart itself, just to solely use the scroll bar to navigate along the chart. I've

问题 I have been trying to find a solution, be it a macro or a simple solution, to create and format charts in a powerpoint presentation. So far I could not find anything that would solve my issue. The idea is to source data from a fairly big excel file and then create several charts on several powerpoint slides. That is, one big excel file and 10 powerpoint slides, with 8 individual charts on each slide. I tried this: http://mahipalreddy.com/vba.htm#ppgraph, but that did not help at all. How can
