I am trying to create an animation layer using a CSV file, but the layer appears blank with small "time frame size".
Attached images have sample data I am plotting with 'hour4' as the time field.
The layer appears blank until I select 'Time Frame Size' as 1 year. Ideally it should work with 'Time Frame Size' = '1 day' as my data is at date level with date ranging from 2016-08-08 till 2016-08-23.

For the time series chart, on the initial load, we are displaying data aggregated for every 1 hour. when the user zoom in( for example for 4 hours) we see only 4 samples, instead, can we pull more data from the server which is aggregated for lower interval like 30 or 15 and display it in the chart when the user zoom in, display higher interval data on the zoom out.
On zoom in display lower intervals new data like more samples.
On zoom out restore the data which was already available.
Checking if this feature is available or not.
My problem is: I'm strugling with Power bi trying to correct a default behaviour of the line chart. In this case when I try to filter my data for periods of 2 to 5 days the hours of the day appear in the X axis. Like I show in the image below. In my date hierarchy I have specified my date column with the format (dd/mm/yyyy) and the column is of the type "date", but he hours of the day still appear.
How can I get rid of the hours of the day when I select only 2 to 5 days in the slicer of time??
What I've tried: I've tried to change the date column in my line chart visual so that only the month and the day appear but when a monthly period of days is selected the visual isn't able to show all the data at once and the user needs to scroll in the element, so it is not a solution. I've also tried to change the format of my date column but without sucess.
The desired result must show only the days without the hours of the day like the image bellow:
Links I've followed but sadly didn't help:
Power Bi Axis X and Y
Core plot x-axis labels are not shown
In Power BI X-axis label, how to show only week starting day instead of all date series?
Can Power BI add range selection to a Line Chart?
I'm graphing weekly total page loads per 1000 students, which is easy enough when the pill for the page load variable is set to 'sum', and the date pill is set to 'week number.'
BUT, I also have a table that lists individual dates on which important policy changes occurred, and I want to draw those as vertical lines.
Using a dual axis, I have been able to plot the specific dates as lines, but because the resolution of the date axis is set to "week", it lumps all dates in the policy change table that occur within a single week into one, or possibly omits dates that don't land on the right date for that week, and therefore I don't get individual lines for every policy change.
weekly resolution, dates omitted
I have been able to approximate what I'm looking for by setting the date pill to 'day,' and then doing a rolling average of the page load values--but this doesn't represent the page loads in the way I need it to.
rolling sum, not the same calculation, but includes dates
I need either a way to layer two charts on top of each other, with different x-axis resolutions, or possibly the correct calculated field that gives me the straight up weekly sum of the daily total page loads for successive weeks, so I can use the 'day' setting on the date-time access but still get the weekly values I want, and then plot all dates in the policy change table.
Currently, I'm having trouble to force the highstock chart to display a blank space up to the current date. It focuses the data I give it.
What I have is:
What I want is something like this
As you can see I want the data to stop at the date of the latest data point and then the graph should show a blank space and stop at the current date. Obv there is not data points for those times
You can control how empty points, and missing points are shown by looking at:
xAxis.ordinal
In an ordinal axis, the points are equally spaced in the chart regardless of the actual time or x distance between them. This means that missing data periods (e.g. nights or weekends for a stock chart) will not take up space in the chart. Having ordinal: false will show any gaps created by the gapSize setting proportionate to their duration.
xAxis.max
The maximum value of the axis. If null, the max value is automatically calculated.
plotOptions.series.connectNulls
Whether to connect a graph line across null points, or render a gap between the two points on either side of the null.
Which means that for your graph, you will want to set:
xAxis: {
ordinal: false,
max: (new Date()).getTime() //to set the current date and time as a maximum
}
Given the data arrangement in the image below (from google sheet) I tried to draw a chart showing time consumed by each activity, each activity has a start time, the end time of an activity is the start time of the next activity, I couldn't find a way to visualize such arrangement, is it possible ?
Update: Solution
This is what I reached now
Also I don't have to write end time, here is how I did it
End
=INDIRECT(ADDRESS(ROW()+1,COLUMN()-1))
Duration
=C:C-B:B
Minutes
= D:D * 24 * 60
Note: To draw the chart I had to move the "Minutes" column to the right, i.e labels column has to be on the left for the chart to draw properly.
After that you can hide helping columns C and D as they are just created for intermediate steps.
Yes, you may build a Pie chart based on time entries, but you need to convert time format into number format.
select column with time
go to menu Format → Number → Number
Or, for more visual, convert time formatted numbers into number of minutes:
= Time * 24 * 60
And then draw chart:
