Hi! Im working on a view which contains only a powerchart where i want to display some historical data but before showing the data i want to apply some operations to. Im passing as expresion (where i'll be adding the parameters) with the path of the tag. This is not my problem, my problem is that i'm not able to iterate over dataset rows and apply a multiplication of the data via scripting... Any resources I can check so i can show data propperly modified??
Thanks in advance.
You'll have to use another chart type. The PowerChart doesn't permit any custom operations between the historian output and the chart display.
So what chart would fit my needs? Thanks for fast answering
Start with the TimeSeries chart. Place your historian binding on a custom property. Then you can process the result as you see fit for delivery to the chart's data series properties.
Ok i'll try to bind data as tag history and then apply my changes. Thanks
