Hello Arthur,

CategoryDateTimeAxis.BarTimeFrame is a property which allows you to specify the time for 1-bar (or one point) on the chart in seconds, e.g. CategoryDateTimeAxis.BarTimeFrame=900 means each point on the chart represents 15 minutes.

This is used for financial charting to assist the range and zoom calculations in the X-axis.

Are you binding to this property? If so what value are you setting? Please set -1 for “Automatic” (timeframe calculated by axis) or an explicit value greater than zero.

Many thanks,
Andrew

    Hi, AndrewI'm not using BarTimeFrame and exception generated sometimes. Can I NOT use BarTimeFrame? If not, I'll try to set it to greater than 0.Thanks, Arthur

Hi Arthur,

This exception can occur during SciChartSurface rendering. So there are quick tips for you:

  • if you don’t use CategoryDateTimeAxis(default), ensure that you changes it before the surface is rendered
  • if surface’s DataSet is Null or empty when the rendering pass starts, this exception will be thrown as well

Please, try out this and give us any feedback. If doesn’t help, could I ask you to post small example which reproduces this issue?

Best regards,
Yuriy
