Hello dear colleagues, This is a question about **Power Chart.** I have a user who does trends display configurations using the browser tag. But he wants to **keep all his setup** to use them during the next sessions. He also need to be able to switch from on trends setup to another. Is there a way to **save and restore** Power chart configurations to **files or by another means**? Else, what is your best or recommended way to comply with my user requirement ? Thanks Cyril ---

Check this exchange resource: [Ignition Exchange | Inductive Automation](https://inductiveautomation.com/exchange/92/overview) It saves the data directly into database tables and then allows retrieval of that data. Oops... this is Perspective, not Vision. Try this for inspiration: [Ignition Exchange | Inductive Automation](https://inductiveautomation.com/exchange/2339/overview) ---

A possible solution is to save the config as a json encoded string into a dataset on a button press. You could then generate a dropdown that will get values from that dataset. If you din't want people to see other options, have a column in the dataset with the username, and just show options with matching usernames. This could also be done with a database and named queries ---

Thanks @Hayden_Watson and @bschroeder I tray something (dirty) like that, but without success. Save json pens to customs : ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/4/c/4c6f7e99199cf6da0e7616a7f299e1e468ed79b5.png) Button with onclick action : ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/e/6/e6983426dd2aa7fd8524edb20f878942160d3a4f.png) Custom mapped to memory tag array.

You don't want to save the entire power chart... you want to save the _configuration_ of the power chart. ---

I would add two buttons and a drop down as a basic example. A save button would have a script something like: ```auto dataset = system.tag.readBlocking("Your Dataset Tag Here")[0].value axes = system.util.jsonEncode(self.getSibling("PowerChart").props.axes) pens = system.util.jsonEncode(self.getSibling("PowerChart").props.pens) username = self.session.props.auth.user.userName dataset = system.dataset.addrow(dataset, ["Option name", axes,pens,username] system.tag.writeAync("Your Dataset Tag Here",dataset) ``` Have some dropdown with a binding to find the names of your options. then a restore button with something along the lines of: ```auto dataset = system.tag.readBlocking("Your Dataset Tag Here")[0].value for row in range(dataset.getRowCount): ...iterate through dataset to find the saved data.... self.getSibling("PowerChart").props.axes = system.util.jsonDecode(the_axes_value) self.getSibling("PowerChart").props.pens = system.util.jsonDecode(the_pens_value) ``` You'll need to handle the bindings, some way of entering the name of you new saved option etc. But that should be a start ---

@bschroeder, yes, I would like to save pens part of json tree only But, I will try you second link : _Tag Historian Viewer from @erik.forsgren_ It seems to do what I need exactely. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/3/4/3425dd60b40cad25bbebbae567c6227fb5012147.png) ---

I finnaly find a solution with a customized version of : > **[Ignition Exchange](https://inductiveautomation.com/exchange/2339/overview)** > > Discover, share, and download community made Ignition resources in collaboration with your organization or the Ignition community. It did not work out of box with sqlite database, but I manage to do it. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/b/e/bed60d913190347a7a056434edf68e48096b8347.png)
