Sorry, It’s been a couple of years since I used Ignition. I’m changing the tag path for a current pen. But if I try to close and commit and save changes, when I reopen it the tag path goes back to the original.

Are you using a template for the trend? If it is the Adhoc Trending tool, it is most likely a template and you would need to change it in the template for it to load that particular tag on open.

Thanks, not a template, but it looks like they are passing in the the tags into the chart. Just have to figure out where they’re coming from. This script is on the container.

`'''if event.propertyName == 'title':`  
`title = event.source.title`  
`dataset = event.source.dataset`  
`pyDataset = system.dataset.toPyDataSet(dataset)`  
`chartData = `  
`for num in range(pyDataset.getRowCount()):`  
`if pyDataset[num][1] == title:`  
`chartData.append([pyDataset[num][3],pyDataset[num][4],'MinMax',pyDataset[num][5],pyDataset[num][6],1,'color(255,85,85,255)','',1,1,0,1,1,pyDataset[num][2],0,0,0,1,'',0])`  
`chartHeaders = ["NAME","TAG_PATH","AGGREGATION_MODE","AXIS","SUBPLOT","ENABLED","COLOR","DASH_PATTERN","RENDER_STYLE","LINE_WEIGHT","SHAPE","FILL_SHAPE","LABELS","GROUP_NAME","DIGITAL","OVERRIDE_AUTOCOLOR","HIDDEN","USER_SELECTABLE","SORT_ORDER","USER_REMOVABLE"]`  
`event.source.getComponent('Easy Chart').tagPens = system.dataset.toDataSet(chartHeaders,chartData)'''`

They are coming from a `dataset` property on the coponent where you copied this event script:

```python
dataset = event.source.dataset

```

Thanks,

I found that they were pulling all the pen information from a DB. Then just using one screen for all the trends.
