Given that each series caps out at 32000 points, 8 series are required to plot the full 256000 points...
In the company that I work for we have several web-based applications that require charting of data in one form or another. We are therefore investigating different ways of reusing the efforts we put into providing charts.

I'm about to start working on a new .NET project where I'm going to need to put real-time data from a hardware device on a chart and I was surprised to find out that ZedGraph development seems to have died out (last activity on the wiki is noted in late 2007). Is that true? If so, are there any good open-source replacements for ZedGraph...

If you're familiar with ASP.NET's Charting controls, the Chart object contains a number of Series objects - which are series of datapoints that can be charted.

I am making a small app that plots financial price data and since the finance markets are closed on the weekends, I have no data for those days. By default the chart, found in the new WPF Toolkit, shows a large gap between Friday and following Monday and this behaviour is not acceptable. I am trying to figure out a way to "hide" the week...
