having two modules on x axis

I have a column chart on power bi with option OI against each strike and for each strike for all of the dates. so in short it has two layer in x axis 1st layer is strike and 2nd layer is date. for all the strikes in the table there are subgroup for all dates in the tables on x axis. and y axis is OI so I have bars with value of OI for each date for each strike. the problem is the chart is too long and I have to scroll so many times to see the full chart as there are so many strikes. I want it to be condensed to show the whole chart in one page. But I cant find a way. I tried tableau but it doesn’t deliver good visual of the chart. I was hoping if it can be done in excel but I couldn’t find a way to add two layers into the x axis. I am hoping anyone here might know how to do it in excel. Or some other way… please helpthe chart in power bi
