We've setup a new Splunk dashboard and I'm looking to improve the trend graphs/panels.
We now have three panels each telling us something about a specific type of event. These panels are shown in the screenshot below:
Top to bottom,
the first shows the number of events in the current rolling period (of 30 days).
The second shows a trend graph of the number of events every day over the past 3 months.
The third and last shows the number of events in this year to the current data (YTD).
I'd like to clean this up and combine it into one panel. Ideally it would look something like:
I've been messing with CSS files, but that is not a sustainable solution.
Also I've found the Splunk documentation on how to Generate a single value. This give me part of what I'm looking for. But this lacks the Year to Data value and I need the trend line to be more prominent.
Any suggestions to how to make this work?
You want to create a custom visualization of a numeric value. I would suggest you start by looking into existing numeric value visualizations from Splunkbase, then customize the visualization code (html/css/js) to do what you need it to.
From a quick view I just had, there is Number Display Viz which also has source code available under the GPL on github: https://github.com/ChrisYounger/number_display_viz
To show all three datapoints on a single panel, you can either tweak the html to retrieve data from three different searches, or use sub-searches to provide all data as a single result.
Consider putting all three visualizations in a single panel. You'll need to edit the dashboard's source to do that, but it's very simple. Just remove the </panel></row><row><panel> tags between the visualizations.
A simpler option would be to move the three panels onto the same row so they're next to each other.

I have created a dual axis chart where I'm graphing the arrival time and the departure time in the same graph, and showing the sum of the number of records as the rows.
By default Tableau adds the "Measure Names" into each of my columns Marks and I get an automated Legend showing the "Number of Records" in one colour.
However, this is not useful at all...
I want each time variable (eg. arrival time) to show up in a different colour. The only way I have been able to do this is by removing the "Measure Names" pill from the Marks card and then setting each axis to have its own colour. But as soon as I do this, the Legend disappears and now I finally get a nice graph with a line in each colour, but no legend to show what line is assigned to what colour.
Also the Legend option gets disabled when I use this layout.
How can I add the Legend to this?
Please note that the solution in this post doesn't help to answer this question.
You should be able to create 2 calculated fields that basically mimic Number of Records like
SUM([Number of Records])
Once you have 2 calculated fields, you can name them each what you desire. Then you should be able to use measure names and those separate calculated fields on each card of your dual axis.
Many, but not necessarily all, views people want to make with job start/arrival and end/departure records are easier if you reshape the data to have one data record recording each state-change event, tied by a common key.
So if your data has columns for Date, ID, Event, User -- where Event can be either Arrive or Depart -- then most visualizations will be much easier. In this view, each user that has arrived and departed will get 2 records instead of just 1. And customers that have arrived but not yet departed will get 1 record.
You can leave your original data in its original form and create this reshaped view in a Tableau Data Source using either Tableau Prep or the DataSource page in Tableau Desktop. You'll need to use the Union operator. That way you can have another data source that points to the original format if that is useful also.
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:

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
Would you please help me (total beginner) to prepare a VBA macro that would open a sheet on the background and import specific selection as shown below:
Let's say we have downloaded wordcount analysis (xlsx) like this downloaded from a CAT tool for testing.
Now I would need to add a macro to my main sheet that would read lines starting (Column A) with "All". If "All" then I'd need to record columns of that line (specficilly Columns A - O) in array / hashtable?.
Please take a look at this image that summs it all (better than explaining it for me :-)
Let me know in case you need to know more details.
All tips / suggestions are greatly appreciated.
Many thanks!
My suggestion (I'm a beginner too) would be to use the Macro Recorder. Great tool to learn (example).
start recording
filter for 'ALL'
copy/past the Cells
stop Recording
Then have a look at the recorded code and adjust it :)
Looking at your data and the final layout you are looking for, using a Pivot Table would provide you with all of the flexibility you need.
You can:
filter which data to display
generate calculated values based on data in other columns
choose what order your columns are displayed
dynamically change the layout if you decide you want a different view
From your data, I was able to generate the following Pivot Table in about 15 minutes.
There are several good, simple tutorials on building Pivot Tables. A Google search will turn up plenty.
Things you will need to learn about for your particular problem:
Classic display (I used the classic display to get this particular layout)
Calculated Fields (many of the columns in the pivot table are calculated based on your spec). There is a maximum string length of 255 characters for a field calculation, so you may need to rename some of the columns in the original data set.
Of course, basics of Pivot Tables
Loading new data and updating your pivot table
Good Luck!
Noob here, I have a table with different entries (rows) per different (repeating) regions.
I'd like to be able to display the data rows filtered - matching that particular region thanks - so I get those particular fields related to each region as a tooltip on a map. (I know how to build the map)
Thank you
Just dragging the fields you want to Details or Tooltip is not doing the trick?
Putting a measure on a shelf (other than filter shelf) includes that field in the visualization query results -- i.e. applies the chosen aggregation function to yield an aggregate result value for each partition of the data (as specified by the unique combination of dimensions)
Putting a dimension on a shelf (other than the filter shelf) also includes that field in the query results, but since the dimensions define how data rows are partitioned, it can affect the level of detail of the query. You'll notice this often as suddenly getting many more marks in your visualization after you add a dimension to a shelf. If you are familiar with SQL, dimensions define the fields that follow the GROUP BY keyword.
EDIT
Thanks for the addition, #AlexBlakemore. I've never said dragging a dimension would not work, only that it wouldn't work as the OP wanted it to (basically the same as you're saying).
And though everything you said (above) is true, it's particularly not exact when it comes to maps. Yes, dragging a dimension will further partition the data, but it will not create additional marks on a map (unless it has also geographical properties). Rather, the tooltip will get the first occurrence of that dimension, and display data for that only. For instance, if you drag "Product" to details, and the possible values are "Bread", "Coffee" and "Milk", it will probably just show "Product: Bread", and the measures for "Bread" only. So yes, it will partition, but no, it won't create additional marks.
Back to OP problem. What I believe you want is a tool tip with all values of the dimension (in my poor example you'd like to see "Bread, Coffee, Milk"). Tableau does not have functions to aggregate strings yet, so it's hard to do so.
What I would suggest is to create a separate sheet, and just drag the dimensions and measures you want to rows. Then put it side by side with the map on a dashboard, and use the map as a filter. Then, when you click on a country/region/city, you'll see the data of that region on the other chart.

I have sales data that I'd like to plot on my chart. However, at a specific point in time, we had a change taking place I'd like to ensure is clearly visible in the chart, preferably by dividing the sales data (which is stored in a single SQL Server column) into two different chunks, which would allow me to then treat them as different data series.
I used to solve this in Excel by storing the post-event data in a different column (by simply dragging them to a different column), and thus I was able to treat them as a different series (the blue and green line in the chart below. The red and orange line are pre-event and post-event averages):
I'd like to reproduce this effect in SSRS, but am not sure how to tackle it. I've tried using an approach where I added two category groups, both pointing to the date-time column, and applying filters to them (one <= the cutoff date, the other >=).
I then added my sales data twice, with the idea I could somehow connect them to the individual category groups, but that does not seem possible.
Has anyone tried anything like this before, or would have a different approach to achieve what I'm trying to get?
Thanks!
I managed to get this to work, and figured I'd share how to do it.
My dataset contains a field called DATEKEY, which stores the date in the format YYYYMMDD. It's possible to use this in an expression and evaluate the date for a specific row. In case the expression evaluates to true, we display the value. If not, we display a blank string.
In case we want to show the values prior to the date, the expression would be:
=IIF(Fields!DATEKEY.Value <= 20130601, Avg(Fields!My_NUMBER.Value), "")
The second series can then be made by reversing the symbol:
=IIF(Fields!DATEKEY.Value >= 20130601, Avg(Fields!My_NUMBER.Value), "")
The graph then looks like this:
