Bubble chart Bubble size

[User (Legacy)]

I using the bubble chart to display x,y values and using the third

cooridinate to set the size of the bubble. I set the size of the bubble to 5

and all the bubbles on the graph are the same size.

My issue is that when I display the graph with a different set of data the

bubble is not the same size as with the first graph. I am setting 5 as the

ChartFX1.ValueEX(1,x)   for both graphs only the x and y values are

changing. Does the scale of the graph also affect the size of the bubbles? I

need the bubbles to always be the same size on all the graphs regardless of

scale. Can I do that?
