How to let user create Annotations on MSChart?

由 走远了吗. 提交于 2019-12-19 10:12:12
问题 How do you create an Annotation on-the-run and how do you enable end-user placement with Annotation.BeginPlacement() ? I've tried to do this in multiple ways, but cannot get it working. It should render itself in real-time after the BeginPlacement() has been called. Documentations on this subject is little to none - and mostly none - so I'm not able to find any help for this problem. What I've tried so far, is to create an annotation and place it with AnchorX/Y, set all Allow- flags to true

问题 How can I draw an stock chart or a line chart with hundreds points? I disabled animation in regular line chart, but not successful and still too heavy and slow. 回答1: I've recently written a blog post on creating stock charts in Ext JS 4 - http://www.scottlogic.co.uk/2011/12/ext-js-4-stock-charts/. It uses a couple of hundred points and performs fine in modern browsers and isn't too bad in IE7-8. This said however, even after messing with the Ext JS build system, the minimum Ext build required

问题 I've just upgraded to .NET 4 and my ASP.NET Chart Control no longer displays. For .NET 3.5, the HTML produced by the control used to look like this: <img id="20_Chart" src="/ChartImg.axd?i=chart_5f6a8fd179a246a5a0f4f44fcd7d5e03_0.png&g=16eb7881335e47dcba16fdfd8339ba1a" alt="" style="height:300px;width:300px;border-width:0px;" /> and now, for .NET 4, it looks like this (note the change in the source path): <img id="20_Chart" src="/Statistics/Summary/ChartImg.axd?i=chart
