Hi
Eslam,
Thank
you for reaching out. We reviewed your reported scenario using the sample you
shared. Since we were unable to run your attached sample, we recreated a
separate sample using the same chart code, styles, and with local data. In our
testing, the chart occupies the full available width, and we did not observe
any empty space before the chart.
For
your reference, we have attached the tested sample and screenshot below:

Sample: https://stackblitz.com/edit/react-mmjken4q?file=index.js
To
help us analyze the issue further, we kindly request the following details:
- Please try to reproduce the issue using the above
shared sample.
- Share your modified runnable sample where the problem
occurs.
- Inform us if you have applied any additional
customizations.
- Specify the Syncfusion package version you are using.
We
also noticed that your sample references ej2-react-charts v21.2.9. Please
confirm whether you are still using this version or a different one. The sample
we provided uses the latest version.
Kindly
let us know if you have any further concerns or need additional assistance.
Regards,
Durga
Gopalakrishnan.
