Greetings from Syncfusion.
We have analyzed your query. We suspect that you have mentioned to reduce around white space means chart default margin size(10px). If this is your query, you can reduce the space using margin property of the chart. Using this property we can align top, bottom, right and left spaces of the chart container. Please find below code snippet for how to use margin in chart.
Kindly check that above sample and revert us back with more information about your requirement on which space you want to remove, if this is not your requirement.
