I'd like to display a moving average as a number not as a graph.
Is it possible to display a number in graphite?
You can get all graph data by adding param format=json to the url. It is not a single value, but it is the only way. Example
This will render png graph
http://graphite.loc/render?from=-1minutes&until=now&width=400&height=250&target=movingAverage%28carbon.relays.local.connections%2C10%29&title=movingAverage%28carbon.relays.local.connections%2C2%29
but with format=json
http://graphite.loc/render?from=-1minutes&until=now&width=400&height=250&target=movingAverage%28carbon.relays.local.connections%2C10%29&title=movingAverage%28carbon.relays.local.connections%2C2%29&format=json`
it will output json with target name, datapoints (values with timestamp)
[{"target": "movingAverage(carbon.relays.localhost.connections,10)", "datapoints": [[154069.8, 1452992400]]}]

I have an excel sheet which I am plotting two values over time. But when I plot it in Power BI it shows the sum of those values in y-axis rather than the actual value. The plot looks like the following.
If you see the y-axis they are in billions. But if you see the actual data below its in hundred thousands range.
If I use date hierarchy instead this is how it looks like.
Since your data is on specific days, you should use dates on your axis rather than weekends. When you have weekends on the axis, it groups all the days within that week together, which is not what you want.
Edit:
After looking at your file, it has nothing to do with dates after all. It looks like the data is recorded at a weekly level. The reason its adding up like that though is that for each date there are a bunch of different rows that correspond to different geography (your geo column has state name abbreviations).
If you add a slicer for geo and look at the chart for a single state at a time, then I think you'll get more what you're expecting.
I read every possible forum and I couldn't find a specific answer. I'm new to Tableau and I need to perform what I thought would be a very simple task but I can't figure it out.
I need to create a chart with multiple lines plotted in the same graph. On one column, I have a timestamps in seconds (decimal). For each timestamp value, I have 4 columns associated (Temperature, Pressure, Humidity, Voltage) and I need to visualize how they trend over time. The data in Excel looks something like this (I simplified it for visualization purpose):
In Excel, it takes me less than seconds to obtain a chart that looks like this:
How can I replicate the same exact chart in Tableau? I would like someone to tell me exactly how each column should be formatted, if the data has to be a dimension or a measure and data type for each (string, number etc) and what steps to take in the chart. I would do this in Excel but the file is almost 1M rows and Excel keeps crashing.
drag & drop measure values & timestamp.
EDIT - first make Timestamp a dimension instead of a measure, and make sure it remains continuous instead of discrete. So you should not see the word SUM in front of Timestamp
remove no. of row & timestamp from the measure values.
uncheck aggregate measure.
EDIT this step is not usually needed or desirable. If you do have multiple recordings per Timestamp, you will want to select the best aggregation function for each measure, perhaps AVG or MEDIAN instead of SUM
select line from mark and drag measurement to color
If your X-axis is a Date Column, (i.e. You have a list of dates on your X-axis)
Drag your 'date column' to Columns and choose Month/Year/Week etc. and make it continuous
Drag 'Measure Names' to Filters and choose your Measures
Drag 'Measure Values' to Rows
Drag 'Measure Names' to the Colors section of the Marks card
I have data with lat/lon attributes that I'm plotting onto a map. I then use the "line" mark to link the data points. It seems to automatically order them by the latitude attribute, which happens to bring two of my data points out of order:
How can I manually change the order of the linking?
Thanks!
There is a path shelf in Tableau, details of the usage can be found here:
http://kb.tableau.com/articles/knowledgebase/using-path-shelf-pattern-analysis
You just need to create a dimension and give each coordinate of your path a running number. Once you drop that dimension on the path shelf, Tableau will use it to determine the order of the coordinates.
I want to plot stacked column graph through Shinobi.
Please referer attached screen shot for desired graph.
Can anyone please suggest how to pass data point for the same.
Disclaimer: I am a developer at Shinobi Controls.
To get columns to stack you need to create a series for each column you wish to stack.
To get the series to stack, you must set each series' "stackIndex" property to the same value.
For example, in your image you will need 5 SChartColumnSeries with their "stackIndex" value set to the same value, lets say 1.
Now you can add one datapoint for each series with the same X value but with different Y values.
In my tableau visualization I need to show the change in a metric over every minute for a day.
I have a "minutes" table in my db. Each row has columns: "minute_id", type int
"minute", type string: carries the value of the time eg: "05:33, 12.30, etc"
"min_date_time", type datetime: carries the value of the time datetime equivalent of the above string value eg: "2013-11-01 2:30:00 AM, 2013-11-01 2:31:00 AM, etc"
A second table called "demos" has all the metrics that are shown for that specific minute.It has relevant columns as follows:
"minute_id", type int: foreign key for the minutes table
"ind2plus", type float: value to be displayed on the y axis for each "minute_id"
This is what I have so far:
The problem Im trying to solve is:
On the X axis currently the displayed unit is "minute_id".
I would like to keep minute_id as the values on the X axis,
but I would like to change the values "displayed" as labels on the X axis from
the int value in the "minute_id" column to the string value in the "minute" for every "minute_id".
How do I do that? Please advise.
UPDATED GRAPH:
If you have a true datetime field in your data, you get more flexibility by using that field for most situations.
So I suggest putting your min_date_time field on the columns shelf to replace minute_id.
Tableau allows you to use dates and time fields in many different ways for different effects -- so many options that it can be confusing. You have to choose whether to treat the field as a dimension or measure, whether to treat it as discrete or continuous, and what level of granularity to use (hour, minute, month, exact date ...) It will take experimentation and experience to get comfortable with implications of the different choices.
For your graph, I would start by choosing a continuous dimension at the minute level. You can adjust the settings by clicking the little triangle on the right of the pill on the columns shelf. The truncated date settings are the second batch of date menu options and result in a green pill. Once set, you can drill up/down granularity with the + on the left of the pill.
Finally, once you are happy with your chart, you can change the formatting instructions to affect how dates are displayed on the axis. Right click on a number on the axis, choose format, and then in the format pane, under scale you should see a pull down labelled Dates. You can choose one of the existing date formats or enter a custom one. The format strings are pretty much what you expect.
