Basically, you can show whatever range of the axis and usually this should not affect the performance, unless huge amount of ticks is generated. You can improve this by reducing the number of ticks via the SmartLabelsMode of the axis, or via its MajorStep and MajorStepUnit properties.
Also, the performance can be low if there is a large amount of data points shown within the viewport, as already discussed in the other forum.
Yes I am generation 100 million ticks. I assume thats the problem?
Also is there a limit to how much I can zoom in ? What is zoom defaulted to?
Showing 100 million ticks at once means 100 million UI elements for the WPF rendering engine, which is pretty heavy operation. To minimize this you can use one of the approach mentioned in my last reply.
You can control the zooming limit via the MinZoom and MaxZoom properties of RadCartesianChart.
About your last question, yes, if you change the tick interval, the data points will still exists and the trackball will work.
