I have a reasonably complicated setup with a chart on a control loaded on the fly according to this and that.
Now, the first time the asp.net postback occurs in order to render the chart, all the axes, title, legend etc draw fine. However, the chart series line does not appear, only the 'spinner'. I know the code to draw the line is being run.
On a subsequent postback (e.g. when the browser is resized and I explicitly set chart size), the line draws correctly.
Any ideas why the line should not appear first time?
thanks

I have fixed it by adding a script to queue postback events.
Unfortunately that broke adding docks into a dockzone.
I fixed that by waiting for the postback completed evemt, and calling a 'resize' postback on that to cause the chart to draw.
Unfortunately all that broke the close dock/create dock. That is, if I closed I dock I could not create it again unless there was a postback in between.
I fixed that by setting the CommandsAutoPostBack property of the dock to true.
that was not fun
