Hi there!

To align the zero point on the primary and secondary axis, you can follow these steps:

1. Select the chart and go to the "Format" tab in the ribbon.
2. Click on "Horizontal (Category) Axis" and select "Format Axis" from the drop-down menu.
3. In the "Format Axis" pane, under "Axis Options", set the "Minimum" value to
   Formula:

   0 

   .
4. Click on "Vertical (Value) Axis" and select "Format Axis" from the drop-down menu.
5. In the "Format Axis" pane, under "Axis Options", set the "Minimum" value to
   Formula:

   0 

   .
6. Now, both the primary and secondary axis will start from 0 and align at the zero point.

If the above steps don't work, you can try changing the chart type to a combination chart. Here's how:

1. Select the chart and go to the "Design" tab in the ribbon.
2. Click on "Change Chart Type" and select "Combo" from the drop-down menu.
3. In the "Combo" pane, select the "Line" chart type for the primary axis and the "Column" chart type for the secondary axis.
4. Click on the "Line" chart type and select "Secondary Axis" from the drop-down menu.
5. Click on the "Column" chart type and select "Primary Axis" from the drop-down menu.
6. Now, both the primary and secondary axis will start from 0 and align at the zero point.
