In Format Chart tab, go to Chart Area->Axis->X-Axis, click Gridlines button, untick Is Category Axis checkbox, click Finish, preview. 4. Double click the chart, click Scale button, choose Step Size, enter 15 Minutes, click Finish, preview. Expected result: After set Step Size the scale works correctly.
