I was planning to do a Straight Table chart like this:
The four dimensions should always appear and have exactly the same colors (the only variation is the expression values).
What I have now is the dimensions and the values as I want except for the colors. The initial data is organized in a table like:
Project Status
1 Completed
2 On Track
3 On Track
4 Deviating
So the #RA variation is the percentage of each status value from the total. However, it can happen that in some cases one status value is 0. And I get this:
The condition for the colors is set in the color background expression, like this:
I also have to say that as some fields of the dimension have no values they disapear, so they are forced to appear using the Show All Values in the dimension tab.
Any one knows how to make the colors always fixed for its dimension even when the value is null?
Thanks for the attention

I am trying to create multi-line subplots such that each subplot represents a rating factor on which firms are rated, and each line represents a firm's change in rating over time. Note that I don't have the date field. I have a string field that says which quarter of the year the Mean of ratings belong to.
I'm new to tableau and I created something like this:
I want to create multiple subplots: one subplot for each of the 8 rating features in the above diagram, and the subplot has multiple lines representing the variation over time for each company. I have 10 companies.
Please guide me on how to achieve this?
A rough sketch of how I Imagine the plot to look like is below:
This will teach you how to make a panel chart in Tableau: https://tarsolutions.co.uk/blog/build-a-dynamic-panel-chart-in-tableau/
It shouldn't to too complex for what you're attempting (fingers crossed!).
Building the panel chart is a little tricky in Tableau. Not terribly hard once you understand table calcs. I suggest starting simpler by moving Measure Names from the Rows shelf to the Pages shelf, then creating the line charts you want - 1 per page. Then learn about table calc partitions and addressing, including “At the Level” to have the info needed to define the panels
To make a colored line chart,
You need one field on columns that you set to display as continuous, making it green. If it is a date field, right click on the field and choose from the second set of groups, like month or quarter.
You need a continuous field on the Rows shelf, use Measure Values in your case
Use a discrete field on color to determine the number of lines, say Shortname
Set the Mark Type to either Automatic or line
I am trying to create a report for my stakeholders where we want to check the distribution by values of column1, column2 and likewise. While I could make different tabs for each column, I apparently have 55 columns (all numeric and I will be making bins for them) that the user want to toggle between for comparison on distributions - and coming up with an insight like column 43 is more skewed than column19.
Pet example:
1. Suppose I have data in below format:
2. And I want to create a tableau filter enabling the user to toggle between continents and countries, and get their individual distributions in the same view. I want to keep the measure consistent (population in this example). Something like below:
3. and generating distribution by continent when continent is selected and by country when country is selected
I know if I had wanted to toggle between different measures for the same dimension, then I needed to create parameters, but this is opposite to it (same measure but different dimensions) and I am not able to figure out.
Any comment/help will be much appreciated.
I'm afraid you'd still need to use parameters. There is no equivalent of Measure Names for dimensions so you'll have to create a parameter (I called it Dimension Switch) with Continent, Country, etc. as options and a calculated field that will look something like this:
CASE Dimension Switch
WHEN "Continent" THEN [Continent]
WHEN "Country" THEN [Country]
END
This calculated field will take on the values of whichever column you have selected in the Dimension Switch parameter.
I want to create a calculated column that is equal to the percent of the total of the previous column, but only for the rows that are selected.
For example, the two columns below show rows where I've filtered for only the rows of interest. The sum is accurate, but I want the percent of the total to be only out of sum of the currently selected rows rather than the absolute total (which is how it's currently being calculated). I want the percent of the total to dynamically change depending on what is filtered in the data table. Is this possible?
Image of my 2 columns:
I know spotfire somehow calculates this becuase when I insert a bar graph using % of Total(SumofComponents) the ratio is only out of the current total.
Image of my bar chart:
much like in programming, Spotfire has a rough concept of scope. and unfortunately, calculated columns are above filters in terms of scope; they have no concept of what is and is not filtered.
visualizations themselves, however, do*!
what you can do in this case is to put your expression on the Y axis (it looks like you've done this), and it will respect your selected filters*.
*caveats: there are a few ways that filtering can be negated on a given visualization:
Properties>>Appearance>>Show shadows indicating the unfiltered data. this option shows a grey bar that represents the data hidden by whatever filter selection was made
Properties>>Data>>Limit data using filterings. these options allow the viz to use separate filtering sets ("Filter Schemes" as they're called in Spotfire) or none at all (to ignore filters completely)
Properties>>Subsets. by default there are three subsets: "All Data" which ignores filters, "Not in current filtering" which inverts the filter selection (e.g., if you filter a boolean column to show only TRUE, this chart would show only FALSE), and "Current filtering" which is the default behavior. you can check the online help for additional subsets that you can add.
Does anyone know if it is possible to create a graph(s) at run time based on the dataset?
To clarify, I have a count of patients suffering from a health condition, split by week. I need to make a graph per condition with weeks on the X axis and patient count on the Y. Nice and easy so far.
The problem is that the number of conditions displayed in the dataset will be different depending on the values entered for the start and end dates for the reporting date range.
With this in mind can I create a single graph then tell it to replicate once for each condition returned and only look at the data for that specific condition?
The graphs can't appear in rows as they must aggregate data from multiple rows (where the condition is the same) and plot the various count values over week numbers (the dataset returns a count, a week number and a condition with a group by on the week number and condition)
As an added challenge none of this can be hard coded as the single report has to work across multiple sites.
Thanks

Yes this is possible by first dropping a "Matrix" control into the report surface. With the Matrix control, you're able to display groups of data. In this case, your group will be the condition returned in your DataSet. Each group will have an embedded chart which will display data the same way, but only the data within the grouping you choose.
Step 1: Add a Matrix control to your report surface. Create a Row Group based on Condition (In my example, Year)
Step 2: Right Click the empty column on the right side of the Matrix control, and choose the option for Insert Column > Outside Group - Right. Then Delete the middle column.
Step 3: Right click the Right columns "Data" cell (which should be outside the grouping) and choose Insert > Chart. Select the desired chart type.
Step 4: Resize the column and row to view the chart in more detail. Edit the Chart Data to aggregate what you're wanting to show as the line, and pick your category groups.
Step 5: Test, and revist whichever step above needs adjusting.
I have a matrix table created with Rows as Days ,Columns as Months and quantity of rainfall as the data field(got all this information from same table 'Rainfall'). I have taken this data from a dataset containing multiple tables in SQL. All of this information displays properly.
Now I have many tables with date field in my dataset in tables other than 'Rainfall'.
In the data field of the matix I need to be able to add my own colors using a Switch case.
The Condition I need is "if a certain date from one table matches the date in my report then i want xxx colour."
eg: there is a table called fertilization which has 3 dates. Now if these 3 dates also exists in my matrix then that block should be colored blue.
Can anyone help me. Thanks!
You can also manage it from sql side while retrieving data from Rainfall table.
You can do this using by right clicking the field that you want the dynamic color on and selecting properties. Select Border and then where it says color hit, click the Fx button. Here you can write a custom expression that will change the background color based upon your code.
