Stacked and Line Columns Chart

Good morning esteemed community,

I need to make a specialized Gantt chart, but not having it available in visuals, I decided to do it with the option of stacked bars (In Excel I have made this chart), the point is that I need to include 2 different series (In one project projection (with several fields) and the other series would be the baseline)

Then I give you a screenshot of the chart that in Excel and how I go so far in PBI,

In Power BI I need:

Option 1: Make the gray bar thicker (approx. twice) behind the blue bars or that each gray bar

Option 2: Or that each gray bar is glued to the blue bar above it

The other drawback I have is that to do in PBI I had to put the data in number format, however in the EJe X I need you to show me dates,

Thank you in advance for your valuable support
