    It appears that the “ChartPro” plugin limits the maximum total period of data displayed to 32 days.

    From your answer to a previous post, you mention that the “MINUTE”ly data set is ALWAYS used for the display of the chart.

    Is there any way to extend the maximum displayed period BEYOND 32 days?

    Is there the possibility, when longer-than-usual historical data periods are requested from the ChartPro module, that the server then responds with the “HOUR”ly data instead of the “MINUTE”ly data? This would reduced the overall data content needing to be transferred over the web-browser session, yet still allow for longer overall time periods to be requested and displayed.

    Thanks as always.

    This limit is in the source code. May be it should be moved to options.

    Interesting idea. I will save it.

    For this year, we plan to implement totally new configuration tools. I’m not sure that Chart Pro will be changed in 2018.

    I see this is a very old thread, but does there now, in any way, exist the possibility to have the excellent Chart Pro plug-in historical capability to increase beyond the hard-coded 32 day time-period?

    It would be very useful in some situations.

    ..like the idea of using the “hourly” summary data to save data retention storage requirements in SQL Server Express for time periods in excess of the current 32-day maximum time-span of the charts.

    Yes, in Chart Pro 6 for Rapid SCADA 6 the max period can be set as a parameter.
