Timeseries Chart


Description

The Timeseries Chart, while similar to the XY Chart, uses a datetime value for the Domain Axis instead of a numerical value. This chart is ideal when trying to display Tag Historian data in a Report.


Properties
Chart Options TabProperty/SymbolDescription


Data KeyUnique identifier or placeholder to the data source that will populate the chart.
Domain KeyThe data key that should represent the X axis on the chart. The Timeseries Chart expects a timestamp, while the XY chart can use any numeric value as the domain key.
Pens

Pens represent a series of data. There are several properties for each pen exposed on the Chart Options tab:

Range Key: The key the pen should retrieve data from.

Pen Name: The name of the pen that should appear on the chart.

Preview: Visual representation of how the pen will be rendered. The trend is simply a preview, and does not take the data from the range key into account.

Add Pen

Adds a pen.

Edit Pen 

Opens Pen Configuration area for editing.

Remove Pen

Deletes a pen.
Axes

There are several properties for each axis exposed on the Chart Options tab:

Name: The name of the axis.

Label: Text next to the axis. Commonly used to describe what the values of each pen represent.

Auto?: Determines if the axis should automatically adjust the upper and lower bound of the axis to include all data from each pen. When enabled, the High and Low properties are ignored. When disabled, High and Low will be used.

Low: The low range value the axis will use when 'Auto?' is disabled.

High: The high range value the axis will use when 'Auto?' is disabled.

Add Axis

Add an axis.

Edit Axis 

Opens Axis Configuration area for editing.

Remove Axis

Deletes an axis.
Scripting EnabledEnables the script for this component to run.
Edit ScriptAllows the chart to be modified via Python scripting before the report is rendered.

Example



Example

Dynamically set the range on your chart in the report. This script includes a minimum and maximum boundary so you can set operating ranges. It will throw out values that don't land in the correct range. IE: You don't want to display oven temperatures below 500 degrees, or values of 0 represent bad data.

This code should be placed in the configureChart function definition of your chart. You can access it by clicking the Edit Script button at the bottom of the Property Inspector.

configureChart
# set boundries to throw out 'bad' values that land outside this range
minBoundary = 50
maxBoundary = 100

from org.jfree.data.general import DatasetUtilities
# get the chart, axis, data
plot = chart.getPlot()
rangeAxis = plot.getRangeAxis()
rangeAxis.setAutoRange(False)
ds = plot.dataset

# Find the initial range of the dataset
rangeBounds = DatasetUtilities.findRangeBounds(ds)
rangeMin = rangeBounds.getLowerBound()
rangeMax = rangeBounds.getUpperBound()
# working minimum and maximum values for dataset. these are swapped with the initial values on purpose
currentMin = rangeMax
currentMax = rangeMin

# loop through the dataset to find desired min and max
series = 0 # which pen to search
numItems = ds.getItemCount(series)
for i in range(numItems):
	val = ds.getYValue(series,i)
	# find lowest value that is above the minBoundary
	if val > minBoundary and val < currentMin:
		currentMin = val
	# find highest value that is below the maxBoundary
	if val < maxBoundary and val > currentMax:
		currentMax = val

# calculate 10% padding
padding = (currentMax - currentMin) * 0.1

# set bounds in chart
rangeAxis.setLowerBound(currentMin - padding)
rangeAxis.setUpperBound(currentMax + padding)

# for troubleshooting: look in the console after going to the preview pane to see real values
# comment these lines when done with testing
print "Min: ", currentMin
print "Max: ", currentMax
print "Padded Min: ", currentMin - padding
print "Padded Max: ", currentMax + padding
