Time series graphs deserve to be used to visualize fads in counts or numerical values over time. Since day and also time indevelopment is consistent categorical data (expressed as a range of values), points are plotted along the x-axis and linked by a continuous line. Missing information is presented through a damelted line.

Time series graphs ca response concerns around your information, such as How does the trend change over time?
A crime analyst is researching crime fads in his city to recognize if campaigns to reduce crime have been effective. The analyst provides a time series graph and also compares the variety of incidents over time to the timing of the crime reduction programs.
The graph over reflects peaks in incidents in the period from May 2014 to October 2014 and also aget from May 2015 to September 2015. Tbelow is a decrease in occurrences in February 2014 and also 2015. If the crime reduction programs arisen in those months, that would certainly imply that the programs were reliable, yet just for a limited time.
The analyst realizes that looking at a complete number of occurrences over the two years only tells component of the story. Subgrouping the moment series graph by one more field, such as the crime type, can give more understanding right into the effectiveness of the programs for various forms of occurrences.
The grouped time series graph over indicates that the majority of incidents were categorized as larceny. The counts of larceny show a similar pattern to the ungrouped time series. The other incident kinds, burglary, motor automobile theft, and robbery, have actually reasonably secure counts across the two-year time duration, through the exception of a spike in burglaries in May 2015. Based on what the analyst sees in the grouped time series graph, he will recommend concentrating the programming on reducing the number of larceny crimes in the city.
The complying with cards may be useful to pair through your grouped time series graph:A connected map styled via the same area you used to team your time series graph, such as Day Of Week. When you communicate through the time series graph or the map, you"ll have the ability to watch simultaneous tempdental, categorical, and also spatial fads.A associated bar chart making use of the area you provided to team your time series graph to check out greatest and lowest worths by your chart subteam.
Create a time seriesgraph
To create a time series graph, finish the complying with steps:
Select among the complying with data options:One or even more date/time fields One date/time area plus one or more number or rate/ratio fields One or even more date/time fields plus one number or rate/ratio field One date/time area plus a string field
Drag the schosen areas to a brand-new card.Drop the schosen areas onto the Time Series drop zone.
You can additionally produce charts utilizing the Chart menu above the data pane or the Visualization type switch
You have the right to likewise create time series graphs making use of Time Series, which is accessed from the Action switch
When you drag a date/time field onto your page, the Chart drop zone is replaced via the Time Series drop zone because a time series graph is the only chart kind that deserve to be created utilizing a date/time field.
The Layer alternatives switch opens the Layer choices pane. The Layer alternatives pane includes the complying with functions:The Legend tab is used to view the icons on the chart. The pop out legend button
The fads for the moment series graph deserve to be symbolized as a count of functions over time or as a number or rate/proportion area. The values in the trend line can be calculated as the sum, minimum, maximum, average, percentile, or median of values for the chart.
Average and also percentile are not available for specific remote function layers. If your remote feature layer does not support median or percentile, you can copy the layer to your workbook.
The x-axis mirrors the date/time areas visualized on the chart. The arrowhead beside the area names have the right to be used to choose or unselect date/time fields to screen on the chart. If multiple date/time fields are schosen, the y-axis can only screen one number area or the count.
The y-axis mirrors the count or number areas and statistics visualized on the chart. The arrowhead beside y-axis can be provided to pick or unchoose number or rate/proportion fields to display on the chart. If multiple number or rate/proportion fields are schosen, the x-axis can only screen one date/time area.
You have the right to optionally select a Group by field on the x-axis. The Group by field must be a string area and is supplied to divide the trend line right into subcategories. A Group by area is only accessible on time series graphs containing a solitary date/time field and also a solitary number field or count.
Use the Chart statistics switch
Use the upper and reduced time slider handles or drag your tip on the chart to zoom in. Zooming in updays the time intervals for the plotted information, if applicable. When you"re zoomed in, you deserve to drag the slider to pan the time series to the left or appropriate. Use the Default degree switch
Zooming to a time interval will certainly not pick or filter your data.
Click the y-axis to switch the range between Linear and Log.
How time series graphs work
Time series graphs are produced by plotting an aggregated value (either a count or a statistic, such as amount or average) on a time line. The worths are aggregated making use of time intervals based on the time range in the information being plotted.
The complying with time intervals are provided on time series graphs:One decadeThree yearsOne yearSix monthsThree monthsOne monthTwo weeksOne weekThree daysOne daySix hoursOne hourFive minutesOne minuteOne second
The time slider can be offered to zoom in or out on the moment series graph. If the zoom level passes a compelled threshost, the time interval updates to the correct interval. The largest available time interval for an individual time series graph is the default interval. The smallest interval is the interval that corresponds to the raw information or one second, whichever is larger.

For example, a dataset has information accumulated on a day-to-day basis. When a time series is produced, the default interval is one week. Zooming in on the time series will update the time interval to 3 days or someday, relying on the zoom level. The time series cannot be zoomed in to a smaller sized interval than sooner or later or zoomed out to a larger interval than one week.
