@ankits,
Rendering bar chart with positive & negative values seems to be working fine. Can you kindly create JSFiddle reproducing the issue you are facing & share it with us, so that we can look into the code / chart-option being used by you, understand the scenario better and help you out?
From what we have observed, sometimes things get delayed mostly when we are not able to reproduce the issue or not able to understand the exact scenario, or the solution that we provide may not work properly at your end due to variation in the chart-options being used by you and us. Having a JSFiddle with sample data helps us in figuring out the issue and suggesting an appropriate solution accordingly.
