The histogram i created with my data is shown as a thick block. There are valid hits numbers and dates on the y and x axis respectively, which indicates the data is proper. What can be done to scale it down to an understandable one?
The problem with your histogram is that the data you have indexed would be having a good frequency against the date and/or the data might be months old. So the default interval option for Kibana is set to one year.
You can change it by changing the default time period from "year" to any other smaller values under the section "view" (marked as 1 in the below figure) in the "Interval" dropdown (marked as 2).

I have created the attached dashboard in powerBI. It is a monthly report. That shows the count of item each month. The dates are in this format 1/1/18, 1/2/18, 1/3/18 that the first day of every month
When I created the report powerBI are skiping one month at interval. See Pix attached.
how can i show all months?
Desired
I believe you'll need to change the "X-Axis" type to "Categorical". It looks like it's defaulting to Scalar, which makes a continuous axis and picks tick marks based on available space.
You could try decreasing the font size of the month labels since Power BI might be avoiding overlap. You could also try shortening the length of the label from MMM-YYYY to MMM-YY.
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 want to plot time on x axis and a numeric field 'f' occurring at that time on y axis in kibana 4.
I have changed the data type of 'f' to integer and I can confirm that it has changed from kibana index settings.
However, the only aggregation options available for Y axis are count/min/max/sum etc. This post has an answer for plotting sum but I'm interested in plotting actual values.
Is there a way to do this?
You probably want to check this.
tl;dr
The data you want to plot, are not numbers.
Update your grok filter to something like this %{NUMBER:time:float} instead of whatever you have.
Re-index/re-hash your elasticsearch (i just deleted my data and restarted the whole thing)
Goto Kibana4 -> Visualize -> New line graph
In Y axis select max and in the field, select your number field.
Kibana is plotting a bucket, e.g. every minute.
As such, aggregations are in order. I frequently plot average and max on the same chart to give me a good overview.
If you reduce the time period, the buckets get smaller, but I don't think you can ever make them "just 1 document".
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.
I have a long list of Linux timestamps, representing the second that events occurred over a one-hour period (3600 seconds). Most events are separated by 3-4 seconds but some are separated by one second and some happen at the same second:
1371995100
1371995103
1371995106
1371995106
1371995107
1371995109
1371995111
1371995113
1371995114
1371995118
1371995121
I would like to plot this data as a series of lines representing "event happened", as such (notice that 1371995106 occurs twice):
Actually, since one-second resolution is finer than necessary, but density is important, events that happen at the same time can 'carry over' to the next free second (so it would appear as if the second event that happened at 1371995106 were plotted against the next free second, which is 1371995108):
Can this be plotted using CLI tools in common Linux distros? I have tried plot (gnuplot) but been unable to find examples of creating graphs from one-dimensional data.
You are trying to do a frequency plot. Assuming your data is in a file called data then
set format x "%.0f"
set boxwidth .9
set style fill solid
plot 'data' using ($1):(1) smooth frequency title 'Frequency' with boxes
format stops the label being output with exponents
boxwidth sets the width of the box so there's a gap.
The style is set to filled boxes
smooth frequency sums the y values which are set to 1 by the :(1) the x being the first field in the file ($1).
