I have a list of objects that are sorted by a percentage value in ascending order. Then when I right-click on the bars and under the series data value field, I enter the following expression:
=FormatNumber(Avg(Fields!Percentage.Value),2)
Attached is an image of the chart. I would like to sort the bars in ascending order for each Milestone Phase. How can I do this? It appeared to be working before but I'm not quite sure what happened that caused it to not work anymore. Perhaps before I only had one value per contact and the average was the percentage since there was only one percentage to average out. Not quite sure but I can't seem to find out how to fix this.
I've selected the Series Group Properties, set the Group Expression to Group on ContactName and then changed the Sorting expression to =Avg(Fields!Percentage.Value) but this does not sort the bars in any order whatsoever so I'm not quite sure what to do next.

I build a chart with 2 layers in Workshop, the only difference is the date bucket. As far as segmentation is the same, I would like each layer being displayed with the same color.
In the chart above, you'll see 2 series: one to display the monthly evolution of a property, the second one to display the yearly average. Each series is segmented by the same object (listed in the table above, coming from an hidden filter). This is achieves by defining 2 layers, with exactly the same definition, except the X-axis: the date is bucked either monthly or yearly. The property is calculated on a monthly basis, so the monthly average bucket displays the input value, and the second chart dynamically calculates the yearly average.
The main issue is that the 2 blue lines are not related to the same object.
I also would like, as far as possible, to have only one legend, instead of one per layer. Currently, my workaround is to display in one case the code, in the second one the description.
Maybe I missed something, but I did not find any way to define precisely the chart colors: am I wrong?
Thus, I was wondering if there was any way to sort input data. The filter is based on the object's primary key, is is possible to sort the queryset accordingly ? Maybe the segmentation would be displayed in the same order and the colors match this order.
Or is there any other way to proceed?
The answer to the title's question is quite easy: actually, the segmentation is not exactly the same. In the first layer, the segmentation is based on a code, the second one on the object's name. Thus, the order is slightly different.
Then solution is: use exactly the same segmentation.
I still wonder how to manage the display: view the legend for only one layer, choose lines' colors... But it looks like it's another subject and I'll probably open a new topic.
I'm trying to figure out the difference between the in-application modifier as_rate() and the rollup function per_second().
I want a table with two columns: the left column shows the total number of events submitted to a Distribution (in query-speak: count:METRIC{*} by {tag}), and the right column shows the average rate of events per second. The table visualization applies a sum rollup on left column, and an average rollup on the right column, so that the left column should equal the right column multiplied by the total number of seconds in the selected time period.
From reading the docs I expected either of these queries to work for the right column:
count:DISTRIBUTION_METRIC{*} by {tag}.as_rate()
per_second(count:DISTRIBUTION_METRIC{*} by {tag})
But, it turns out that these two queries are not the same. as_rate() is the only one that finds the expected average rate where left = right * num_seconds. In fact, the per_second() rollup does this extra weird thing where metrics with lower total events have higher average rates.
Is someone able to clarify why these two functions are not synonymous and what per_second() does differently?
I am working on a vizualisation in Tableau that has dimension hierarchy (Product category, product sub-category, product type etc.) sorted descending by number of orders. I want my viz to show by default only first product level (product category) sorted the same way, but give an option to drill down (using "+" on the dimension) to detailed product levels and using nested sorting (again, descending by number of orders).
superstore data sample
I tried using nested sorting option for each product level, but when I drill up and down again, the sorting is wrong again, as if it clears out. I cannot find an option to keep them fixed unless I keep all product levels visible in the viz (without drill-down option).
Does anyone know how can I do it? I tried also different ways of indexing and ranking calculations, but nothing seem to work. I know there is one option to combine hierarchy dimensions and using sorting option on them, but it keeps the viz really untidy.
Thanks in advance!
Tableau will always sort based on the left most column. With the newer nested sorting you can more easily do a secondary sorting. However, when you expand up/down hierarchies like you are noting the formatting might not be retained.
The "classic" way to do this is to create a Rank by number of orders (sounds like you were close on this one). rank(COUNT([Order ID]),'desc'). Make this a discrete measure and put it to the left of all the other dimensions.
To clean it up, you can uncheck "Show Header" on the rank pill.
And if you expand/collapse the hierarchy, it keeps the sorting... Final product:
EDIT: Here is another way to try to accomplish this. It seems to work for 3 levels but starts to break down after that. (It also didn't seem to work well on grouped dimensions.)
Expand the hierarchy to all three levels.
On each dimension, enforce a sort order of Count of Order ID Descending.
I have an SSRS tablix that has three levels of grouping. In the innermost group, I need to sort the rows by how many detail rows they contain. I've researched and tried many custom sort orders on the innermost grouping. I'm working with PHI so I cannot show you my data but here is an idea:
Person A
Monday
Meal 1
Orange
Apple
Meal 2
Carrot
Meal 3
Waffle
Bacon
Milkshake
I need them to sort in order "Meal 3, Meal 1, Meal 2" beneath "Monday"
The underlying datasource is a sql query with a row for each food item. It is complicated, repeatedly unioned, and repeatedly aggregated. I didn't write it, I'm just being asked to sort the resulting report in new ways. I don't want to touch the query because it works and validating a new query is not feasible in the time alotted.
I need a sorting solution in SSRS that will also accommodate doing further odd sorts on the same set (meaning something I can nest other unorthodox sorts into that would fall lower down the sorted list).
I'm using Visual Studio 2010 to build the SSRS report, which I think rules out a number of possibilities, but that's something I didn't choose and can't change.
Look for row groups in the bottom panel (go to view and check on grouping if it's not there). Right click the group for Meal and go to group properties. Go to sorting and click add. For your expression =COUNT(Fields!Food.Value)
Due to the grouping, the count will return the count of all foods in that group for each meal. It should sort it by this count. I believe the correct order in this case would be Z to A (which SSRS will sort numerically high to low).
I'm facing a following problem. In Kibana 4 I've created a line chart based on my input from elasticeasrch but I can only display average, min, max instead of an actual value of the field per time, e.g. sent bytes.
Most answears to that question on stackoverflow are about Kibana 3 (How to create value over time chart with Kibana 3?) and seem to include a Histogram on a X axis, yet I can't seem to find one which will enable me to apply them to Kibana 4. I was unable to find the histogram panel and once I click on the discover tab there is the constant Searching loading.
If I have the following fields in my _source:
{"timestamp":"2015-06-02T10:16:44.0855","time":587,"threadName":"Thread Group 1-957","byte":1372,"status":"false","latence":306,"registerCall":"404"}
and I would like to have the number of bytes on the Y-axis and on the X-axis my timestamp.
Any help in the right direction will be appreciated :)
To create a value over time line chart in Kibana, follow these steps:
Go to visualize tab and select line chart
In the X-axis, select X-axis, Aggregation as Date Histogram and then select your timestamp field as the date field.
Next for the Y-Axis, select Sum as the aggregation and then bytes as the field.
For the X axis, what Alcanzar said is good, but as you notice, the Y axis is problematic.
Sum (suggested by "Limit") works, but since it's aggregated, it shows the total used in each aggregated bucket, but that may be meaningless depending on what you are trying to show. Your question isn't clear on what you want, so I'm just guessing here. One hour of requests, each of which ran for one minute and sent 1 megabyte is indeed 60 megabytes-minutes, if you are trying to show total capacity used over than hour (maybe you are paying a bill based on usage per time). On the other hand, if you are trying to show peak usage in each time, it would be wrong.
You said you already looked and Max and Min and they don't meet your needs. I don't suppose Standard Deviation would be any better?
I have the same concern. The best I've been able to do so far is
display Min and Max simultaneously in the Y axis. When they diverge, I know I'm zoomed out too far, so I zoom in until they align.
This is how I know I'm seeing individual events.
In any case, I share your frustration. I too would like to be able to show time series as easily as I can in, say, Excel.
