We are building an application that receives data at a rate of 264 samples per second. The values we are trying to plot are too large to use doubles so we are using floats instead. As soon as a second or two of data is appended to the chart’s dataseries the application freezes and I get the following message in the debug output window of Visual Studio.

SciChartSurface didn’t render, because an exception was thrown:
Message: Array dimensions exceeded supported range.

How can we get this data to render on the chart without crashing? Ideally we would like to use the FIFO feature of SciChart as well but at this point we would just settle for getting the chart to render.
