BarChart3D (EWO)

[amitgolhani]

Hello,

I want to display periodic information (realtime and offline ) using bar chart. Suggest whether BarChart3D (EWO) can be used to meet this requirement?

Also share example of BarChart3D if any.

Best Regards,

Why not. The BarChart3D however, in comparison with our Trend Widget, does not internally do a dpConnect/dpGetPeriod to get data, so you have to do this in your script and fill the received data to the BarChart

Thanks Martin. Is it possible to plot value-time chart? Suggest method to add time. I want to add time and value for each column.

Best Regards,

The BarChart3D.ewo shows every bar with the same width. When this represents the time, then it only makes sense to use it on fixed interval values.
Check the rowLabels and columnLabels properties to show the timestamp
