@karthi191194,
Chart elements may look blur when either zoom within display setting of browser or windows is changed. Resetting zoom to 100% should work fine in this case. Also the look & feel of title, label and other text elements depends on font-family being used. You can try customizing the font-family of text by setting the fontFamily property.
If the issue still persists, kindly create JSFiddle reproducing the issue you are facing and share it with us so that we can look into your code, understand the scenario better and help you out.
