How to link 2 or more visualisations to affect each others' zoom? (Via Python Scrip)

[Juan Carlos Gonzalez]

I have 3 visualisations that all have geological horizons lines, for the best analysis I need that when i zoom in on one of them the other two would be affected as well, so that the horizons lines be alignes alongside the screen. The thing is, that if i want to zoom in on a particular point of the data to compare with the other visuals i need to zoom manually on each of them and align them by eye.

Hello Juan Carlos,

To sync the zoom visuals, you need to use an IronPython script that can be triggered by Action Controls. You can add this control on a text area just like you did on your left side panel. This script only syncs two visuals, but I am sure you can change the code to your needs and apply the zoom slider range to other visuals

# You will need these two classes from the Application.Visual library: AxisRange and ScatterPlot
from Spotfire.Dxp.Application.Visuals import AxisRange, ScatterPlot
 
# We need to cast the visual parameters visA and visB to ScatterPlot object or whatever visual you are using in your analysis
scatterA = visA.As[ScatterPlot]()
scatterB = visB.As[ScatterPlot]()
 
# We create a reference to the Y axis ZoomRange from the first visual (A)
zoomAy = scatterA.YAxis.ZoomRange
 
# We need to create an AxisRange object based on visual A range settings for Y axis
axisRangeY = AxisRange(zoomAy.Low, zoomAy.High)
 
# And apply this axisRangeY object to the second visual B 
scatterB.YAxis.ZoomRange = axisRangeY
