Visualize Cumulative column data in Google Studio - excel

I have data in CSV as follows
State
Cumulative Number of cases
Date

13-Feb-2021

I want to un-accumulate 'Number of cases' to visualize line chart using Google Studio. X-axis will be 'Date' and Y-axis will be 'Number of cases'.
When I am currently creating line chart with 'SUM' as metric, it just adds us cumulative numbers which is not correct. For example, at 14-Feb-2021, point gets plotted as 7 which sum of of 0+2+5. Ideally I want incremental value to be plotted. Hence for 14-Feb-2021, difference between 13-Feb and 14-Feb as point, which is 3.
Can anyone please share how this can be done? Thanks in advance.

One way that it can be achieved is by:
Chart: Time Series
Dimension: Date
Breakdown Dimension: State
Metric: Cumulative Number of cases; Running Calculation: Running Delta

Excel - Multifamily Value Add Pro Forma Algorithm

I'm putting together a monthly pro forma in Excel for a multifamily property where 10 units will be renovated and each unit renovation takes 45 days. After the unit is renovated, the unit will bring in an additional $100/mo. I managed to calculate the unit-months of vacancy per month via multiple rows of IFS statements and using the actual number of days for each renovation (I used 45 days in the calculation instead of having to roundup to 2 months).
I'm trying to come up with an algorithm to calculate the cumulative rent premium for renovated units in each month using 45 days of unit down time rather than rounding the down time to 2 months.
The solution is easy if I round the downtime to 2 months: The beginning of the row is summed until 2 cells before the current month and we simply multiply by the premium of $100. But I cannot come up with a solution that uses the actual days (45) as I did for unit-months of vacancy.
I'm not even sure if this can be done unless the pro forma is done daily. Is this correct or is there an algorithm to calculate this on a monthly basis as its laid out?
I'd appreciate any help. Thank you for your consideration.

POWER PIVOT linear regression trendline for only last 3 dates

I'm trying to add a column to a power pivot table where it shows the trendline of only the last 3 dates. It's currently being done manually every week in a normal table, using the trend formula, where a chart reads the data. I've changed the data to be pulled into a power pivot table so that it can update automatically every week.
I know you can add a trendline to a graph automatically, but then it is calculated for all data points, not just the last 3.
I've seen code and examples online to add trendlines with INTERCEPT and SLOPE but again that is for all data points.
The graph shows 12 weeks, but only the last 3 should have a trendline that is based only on those 3 points.
example:
I've got a column in the data model that identifies which lines of data falls within the last 3 weeks via TRUE or FALSE. The data in the data model is all files combined and identified by their weekending date, and the %'s are from calculations.
TIA

Line graph, costant value for missing x-axis data

I have a this line graph:
x-axis = date
y-axis= price
for some kind of products I have only one record for month. Le's suppose I want to see Pepsi and Coke's trend over a defined time period. For Pepsi I have a row with a price for each day, for Coke I only have a row for each month. I would like to visualize Coke's data as if I had a normal daily series but with price constant between months. How could I achieve this results without replicate data?
You have to modify the data to generate the desired end result. The software does not allow you to do this natively.

Can Excel aggregate/combine x amount of datapoints and show an average instead of showing all datapoints?

I have a graph with data for each day. I would like to only show the average of the data per week on my graph.
Here you can see a part of the chart. What I want is that these 21 (42) bars (days) shown in 3 (6) bars (weeks).
Can Excel do this without me having to manipulate the data and creating averages per week?
If Excel can't, what would be the most efficient way to create this dataset, if you know my data is organized following this structure (going until 31/12/2017).
I appreciate you reading my question and I hope you can help me out.

Display Grouped AND Individual labels in Excel Bar Chart

I'm trying to create a chart that contains the percentage of Paid Time Off (PTO) that people have used for the calendar year. Each person is on a specific team, so I would like to group the bars per team, but still display everyone's name. Is this possible? I have 4 teams total.
Example Data:
Employee Name Employee Team % PTO Take for Year
Person 1 Team 1 .2
Person 2 Team 1 .35
Person 3 Team 1 .6
Person 4 Team 2 .15
Person 5 Team 2 .3
The x-axis is 0% - 100% and the y-axis should be everyone's name, but grouped by team. Something like this:
Thank you!
Here's two ways to achieve similar result. You have to prepare the data a bit differently, but it's quite easy to generate this kind of a chart then.
The first way is to separate the teams into different series by separating the team values into different columns. This automatically colours the different teams in a different colour:
The second way uses multilevel categories to achieve a similar result. It's a bit easier to prepare the data based on your current data. But you would have to manually colour the teams with different colours:
I used random to generate the data so chart don't have the same values. I also used reverse axis on both charts and added a blank line between the teams to separate them a bit more. Both are simple clustered bar chart (overlap to 100 and 0 gaps), but make sure that you select the whole range of data, as shown on the first picture or excel will plot only a part of the data.
