Hi, In a Perspective PowerChart how can I show only points (dots) without interpolation between them? I tried all the settings in Pen-Display, but I couldn't find a way to achieve this. ---

The PowerChart component is a **trend** display. It doesn't do dots. I don't think dots make any sense for a trend so it's not an option. ---

> I don't think dots make any sense for a trend so it's not an option. And what would be the appropriate control to display curves and notable points (manual sampling data)? It's only a demo: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/7/c74b559a86bbc6bee9a65ad50d5663fbf96eac27.png) The highlighted data comes from a client's database table, and they would like to see the manual sampling data overlaid on the curves. ---

I think I have figured out the problem, and probably some of you have already faced and solved it. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/f/4/f4bab76f6d901afd9147ec6e0811f12fe7446d45.png) As shown in the IA DEMO, if you display a 'pen' connected to a Tag (Datasource History Provider) and set the 'display.type' to Scatter, I get the desired result. If the data to be displayed is taken from a 'DB Table Historian,' it likely requires more information about the 'data.source.' Currently, I have set it up as follows: ```python histprov:ITSIS1SQ003_SAL_DRYBIN_MOISTURE:/table .tblMoistureSample:/column:fdSampleMoisture:/timestamp:fdSampleDateTime:/keycolumn:fdBinNumber:/keyvalue:106 ``` ---

Hi, Could you please report this anomalous behavior as a bug? Alternatively, how can I report it myself? ---
