How to handle desktop application graph tooltip value
I am working on desktop application automation using Test Complete 15.30 version. I am having a scenario to validate graph data to actual data.
In detail the scenario is like : I need to hover mouse on graph data and get the tool tip value at specific point. Then I need to compare that value which actual table value. While doing object spy I am getting the graph output as Figure Canvas.
In the attached image I need to get circle values. Like Row Number and the value.
If I do OCR recognition also I was unable to get that tooltip value. As this is a graphical data validations I cannot go with comparison of images, because my data changes every time.
Kindly guide me to handle graph values in desktop application.
