We have developed a tool to calculate the dew point with a dojox.charting.Chart2D chart. It works in all browsers except in all versions of the internet explorer. Where is the bug? The tool is on the following site: ​http://www.modernus.de/online-taupunkt-rechner/auswirkung-raumluft-temperatur-feuchtigkeit-taupunkt-berechnen THX

It is very hard to tell what's happening because your example is not fully runnable. Please try to isolate your issue in a simple and fully runnable example that reproduces it so that we can investigate it.

Meanwhile you can: 1/ for IE9 change your HTML DTD to HTML5 to benefit from SVG on IE9 instead of fallbacking to VML 2/ Try to keep your "chart" div in the DOM instead of creating it just before the chart is created. I suspect this might be a the origin of your problem.

Because we get so many tickets, we often need to return them to the initial reporter for more information. If that person does not reply within 14 days, the ticket will automatically be closed, and that has happened in this case. If you still are interested in pursuing this issue, feel free to add a comment with the requested information and we will be happy to reopen the ticket if it is still valid. Thanks!
