Velocity Chart in Rally [closed]
(1 answer)
Closed 9 years ago.
I was working on a project to pull out data from rally and create a vellocity chart.
I understand the REST Web Service APIs to use are Defects, Iteration,Hierarchical requirement and Iterationcumilativeflow data.
But can you please tell me how the actual calcualtions are done to calculate the velocity per iteration for a particular project.
What all data are required and how it can be achieved. Right now im able to pull planestimate of all accepted user stories and total plan estimate.
Seems to be a duplicate of Velocity Chart in Rally.
In that post I answered: "I wrote an app recently to calculate velocity. I used the story points of all accepted stories/defects in a time period (iteration/release). My numbers ended up matching what Rally had for my velocity, so I believe that is all it takes."

I am working on a mobile application using Bluetooth sensor. My goal is to visualize Bluetooth data on graph. I have 3 different pages on my mobile application:
First page having 3 channels (you can imagine it as as 1 graph and 3 signals, thus 3 curves)
Second page having 8 channels
Third page having 3 channels
The moment I have many channels (like at the second page, 8 channels) the display is slowing down. It is so slow that I cannot even switch between pages. Like if I am clicking but nothing is happening, totally freezed.
I am guessing it is because of the display library that I am using. For those who already have experienced the same issue, any suggestions about real-time charts in Flutter? I have already tested Syncfusion and it is indeed freezing.
Thank you very much.
We tried to replicate the reported scenario by creating the chart based on the shared information i.e., in first page and third page, we have a chart with 3 series, in the second page we have a chart with 8 series. And updated the charts for every 300ms, and we ran the application more than an hour, unfortunately the app didn’t get freeze. We have tried by adding the data to the chart and not removed any data in the above case.
For better performance we suggest using the fast line series and for updating the data source use the updateDataSource and not use set state. The set state will render the re-render the chart, the updateDataSource method will skip old data points processing, unnecessary bounds calculation, etc. For more information on these, find the user guide below.

We have also attached the sample below which we have used for testing,

Also, if you are using large data set, we suggest using the on-demand loading feature. For more information this, find the user guide and sample below. If this suits to your requirement, you can make use of this.

Answering my own question because having discovered many libraries, I kind of found the answer: I have tested Flutter Charts library. It works perfectly fine and looks good. Even though I am displaying +3 channel per page, it is not lagging and I can easily switch between pages.

Looking for some advice... just finished a ETL pipeline where all data ends up in Amazon Athena. The data is produced via the click stream of high volume mobile apps (so essentially it’s lots and lots of raw events). I want to build a number of dashboards for the business that show different metrics/KPIs depending on the requirements. However, since we’re talking about huge volumes of data I’m not sure the best way to do this? Here’s an example:
I want a dashboard that shows all the MAUs (monthly active users), along with certain pages that perform particularly well and the most popular navigation routes through the app. My thinking is that I’d want a custom query per graph I.e. one query that is counting the distinct IDs each day (and then refreshing every 24hr)... another query for a graph that produces a breakdown of counts per page and truncates... etc
The main reason for thinking this is otherwise I’d be pulling in huge amounts of raw data just to calculate a simple metric like MAUs (not even sure extract would work - certainly wouldn’t be efficient).
Is this completely the wrong approach? Any suggestions/feedback?
Thanks in advance!
It sounds like you have multiple unrelated SQL queries that you want to run once per day, and update in Tableau once per day.
There's always a pull-push between the processing at the source and in the visualization engine.
Set up a Tableau server extract for each Athena SQL query. Build your dashboards, and schedule your extracts to refresh daily. Like an OLAP cube, this will process all the aggregates your dashboards need with the refresh, for better dashboard performance.
Alternatively, if you feel you don't need all the detail in Tableau, then build your aggregates in SQL, so that your Tableau data sources are smaller.
I am looking for a way to increase the queries per day quota for the YouTube Analytics API. I was able to find this question asking the same thing nearly two years ago now - can anyone confirm if the answer is still the same (that there is no way anymore)?

Is there any way to get a list of users for a custom audience?
(2 answers)
Closed 8 years ago.
I finished uploading users into audiences and everything went smoothly, no error received. I checked the audiences and approximate_count shows only a small fraction of the number of uploaded users.
How is it possible? How is this number calculated?
Thanks for the help!
From what I know and from the documentation isn't really possible at the moment.
Which logic stands behind is obscure to me and, frankly, uncomprehensible that one can only obtain an "aproximate" number of users in an audience.
You should apply you own logic and data keeping beyond that.

I am working on an iPhone project related "Create call log with Signal Strength". So we must get required RXQual, RXlevel, FER, C/I values. This app will support for jailbreak.
But I am unable to get any information to access these exact values. I can't go ahead without these values & unable to deliver the project to Clients.
Please suggest & guide me, How can I access these values. Its very urgent.
Can you suggest me the private API's for getting access the signal strength values?
I see you've included the tag "jailbreak", so I imagine that the use of only public apis is a non-issue for you. But for future people coming to this question, there is no way at all to get these values through public (i.e. app-store-legal) methods.
