QUESTION
I'm Trying to create a table visual using Plotly and SQL
I've managed to extract data in the required format and adding a summary row using SQL.
Yet I need to format that last row "Total" to be bold and in a larger font size.
is that possible using plotly in jupyter?
...ANSWER
Answered 2022-Apr-11 at 17:13I don't think Plotly can format individual rows of a table because all of the rows of your selected columns are being passed at once to cells.
However, one workaround would be to make a copy of your DataFrame PQS (so that the numbers in your original table are preserved if you need them), cast this new table to be object or string types, apply all of the formatting changes to these columns (including formatting numbers with decimals and commas), then add the html tag ... to the last row prior to passing this newly formatted copy of PQS to go.Table.
For example:
QUESTION
Please help me with the below issue that I have in Tableau while trying to construct the relationship data model between 4 separate tables(source mySQL):
Dim_Partners, Fact_General_Contracts, Fact_Additional_Contracts, Dim_ThirdParty
I have a main dim table with the names of several partners, primary key Partner_ID. The tables General_Contracts and Additional_Contracts contain this field, so I can do a relationship between all 3 using this key. The problem is that I need to link a fourth table, Dim_ThirdParty, which is another dimension table, that contains the primary key ThirdParty_ID, and I need to link it to the two fact tables, General_Contracts, and Additional_Contracts.
How can I do this efficiently in Tableau? In Power BI the solution is very simple, as you are able to create multiple links between tables. But in Tableau?
I tried connecting the main dimension table Partners to the two Dim tables (see print screen attached), but how can I link the second dim Table, without having to link it to each table separately, resulting in a weird-looking data model? Would it be better to join each fact table in the logical layer?
...ANSWER
Answered 2022-Mar-29 at 15:20Tableau doesn't support any kind of relationship arrangement where you can trace a circle around the tables involved (as you would have if Dim_ThirdParty were a single point in your diagram).
You have two options to resolve this:
- Union Fact_General_Contracts and Fact_Additional_Contracts into a single table with an additional column to allow measures to distinguish between the two (or suitable count columns with 0\null for the wrong row types).
- Use a cross join to merge Dim_Partners and Dim_ThirdParty leaving you with a single dimension holding every valid combination of the two and then join to both fact tables on the pair of keys.

QUESTION
When I apply Month/Year to Cases or Deaths from my data, the values explode. For Cases it goes from approximately 48 million to over 1 billion, and for Deaths it goes from about 700 thousand to over 22 million. However, when I try the same thing with Initial Claims or the Stringency Index, my values remain correct. I'm trying to find the month over month percentage change by the way. And I'm using the Date column. I only select 2020 and 2021 in the filter for Year.
What I'm asking about is Sheet 21.

...ANSWER
Answered 2021-Dec-30 at 16:25Your problem is that the data points are daily cumulative deaths. If you change the date aggregation to anything other than days, Tableau will default to summing the numbers for all the days in the month. This will give the wrong result, obviously.
If you want to show the correct total deaths or cases regardless of the time aggregation (months, days, weeks etc.) then you could use the New Case or New Death numbers plus a running sum table calculation. This will always give the correct total for the time period.
Table calculations will also allow automatic calculation of the period to period % change from the same data fields.
This is a common problem when working with datasets that offer pre-calculated aggregations. Tableau doesn't need that as it can dynamically calculate the aggregation of a field over any given time period but it is easy to forget which field has pre-aggregated data and which has raw data. Pre-aggregated fields assume a particular time period and can't be used for different time periods without disentangling that assumption (which is unnecessary if you also have the raw data (in this case daily new deaths/cases).
QUESTION
I am new to Plotly Dash. I created some Dashboard in Tableau, in Tableau I have a dashboard with a map and a line chart next to it where I can select locations on the map and the line chart shows me the time series line chart from that sensor. I try to do this in Dash and learn some new tools like Dash since I often used Plotly with its beautiful graphs.
I have internal data on a database with some complex logic where I have the locations on a seperate file, since I want to have as less data as possible I don’t want to include lat und lon in the SQL View. For this question I use data available on the web.
I have sensor measuremt data like no2, no, o3 and more from sensors at different locations. My goal ist to have a map with the locations of the sensors. When I click on a location it should show me the line chart and I want to be able to select as many locations as I want so that I can compare the line charts.
Is this possible? I have the line chart, but I can’t connect the part with the map to work. I will use this as a foundation to include many more graphs like bar charts and so on. The top selector will be a dropdown to select the parameter like no2, pm25. Many thanks in advance.
This is the line chart so far:

QUESTION
In my Symfony project, I created a controller and a function to retrieve the content of an APi.json from a site.
I am using HttpClient to grab the content and embed it into a new file in the project.
However when I call this function, I have an error writing the new file:
Http2StreamException> Http2StreamException> TransportException
Body size limit exceeded
this error comes from this piece of code :
...ANSWER
Answered 2021-Nov-27 at 01:42So the limit you are facing comes from the $bodySizeLimit property of the Request class, which has a default value from a const there.
But you can "unlock" it, as this example in the repo itself tries to explain
so basically, you might adjust your code like this:

I'm trying to return a more concise compile error message from a type function and was wondering if it's possible to get a string representation of a type name?
So using this solution (unfortunately the article does not use anchor links so you'll need to search for ErrorBrand) to create an error message, is it possible to do the following:
...ANSWER
Answered 2021-Dec-07 at 12:49No. That is not how Template Literal Types. The "literal types" in the name refers to Typescript literal types:
In addition to the general types string and number, we can refer to specific strings and numbers in type positions.
The "solution" you reference is a hack, and it works by manually coding the error message, e.g. ErrorBrand<'No ponies allowed!'>. It's an abuse of the type system, for questionable added value, in my opinion, but that's a whole other topic.
QUESTION
I have a webpage that displays a react component, TableauReports, which shows a tableau dashboard.
This is the TableaReports component:
ANSWER
Answered 2021-Dec-03 at 13:48This seems to be an external lib that uses vanilla js, it's probably not detecting the dom changes react is performing, thus not updating the viz. In cases like this, personally I just put a custom key on the component. It'll cause a full rerender, so that might not be viable for you, but it should work.
