Set Zoom Sliders in Scatter Plot for X-axis and Y-axis by specifying some input

[Padmini]

I have got some Scatter Plots in a Page and I want to adjust the zoom sliders using some input instead of dragging the sliders to find the exact point. Is it possible?

Thanks

Hello Padmini

You will  need to create an Action Control on a Text Area and associate an IronPython script to it. The script will be something like:
 

from Spotfire.Dxp.Application.Visuals import AxisRange, ScatterPlot

# vis is a script parameter 
scatter = vis.As[ScatterPlot]()

# update X zoom range
axisRangeX = AxisRange(2000,3000)
scatter.XAxis.ZoomRange = axisRangeX

# update Y zoom range
axisRangeY = AxisRange(400,500)
scatter.YAxis.ZoomRange = axisRangeY

 

Another option that requires no coding is to use bookmarks


Check out these articles on how you can use IronPython to programatically set the zoom sliders to a specific position.

Hello Jose,

I modified the script a bit. I am now taking the X-axis min and max values from a input fields and setting the zoom sliders. Similarly for Y-axis.

from Spotfire.Dxp.Application.Visuals import AxisRange
from Spotfire.Dxp.Application.Visuals import ScatterPlot
from Spotfire.Dxp.Application.Visuals import *

typedVisualisation = None
	
for vis in Application.Document.ActivePageReference.Visuals:

	# if it is a visualisation which cannot have a zoom slider, it is ignored
	if vis.TypeId.Name=="Spotfire.ScatterPlot":
		typedVisualisation = vis.As[ScatterPlot]()
	
	if typedVisualisation is not None:

		#if resetX: typedVisualisation.XAxis.ZoomRange = AxisRange.DefaultRange
		#if resetY: typedVisualisation.YAxis.ZoomRange = AxisRange.DefaultRange
	
		MyChart = typedVisualisation

		Xmin = Document.Properties["XaxisZoomMinValue"]
		Xmax = Document.Properties["XaxisZoomMaxValue"]
		
		MyChart.XAxis.ManualZoom = True
		MyChart.XAxis.ZoomRange = AxisRange(Xmin,Xmax);
		typedVisualisation = None

 

Thanks for your help.

Hi Jose,

I have a scenario where I want to set the zoom slider to latest year:

as of now this is the default view of the linechart.

when someone opens the analysis they should be able to see below view by default:

How can I tweak above scripts to achieve this?
