Hello!

In Ignition Perspective I´m using a XY chart with 2 different database binding...same value from 2 different years.  
The results after using same yAxis range looks like:

What I would like now is to overlap the pink and the blue charts

The script transform I´m using for the binding of both dataSources jython is:

```python

	
	code_filter = self.getSibling("TextField_3").props.text
	

	

	resultsDS = value  
	filtered_list = []
	

	if resultsDS is not None:
	    row_count = resultsDS.getRowCount()
	    
	    for row in range(row_count):
	        codigo = resultsDS.getValueAt(row, "CODIGO")
	        if codigo == code_filter:
	            week_start = resultsDS.getValueAt(row, "WEEK_START")
	            pue = resultsDS.getValueAt(row, "AVG_KWIT") # Weekly PUE value
	
	            filtered_list.append({
	                "t_stamp": week_start, # Week start timestamp
	                "process_temp": pue # Map PUE to process_temp
	            })
	

	return filtered_list

```

WEEK\_START is the date of begining of the week (values are calculated weekly)

Is there a way I can overlap both graphs?

Yes, there is a way by adding 2 xAxes each of them linked to a serie and each serie with their own binded data. Maybe unify the range with max and min common values for better visualization.
