Vision XY Chart change shape size

Ignition
1

Ignition 8.1.25

I have an XY chart and I selected lines and shapes dataset type. The size of the shapes is a bit large for my liking since I can have hundreds of points. How can I use the configureChart function to adjust the size of these shapes?

:nerd_face: Got nerd-sniped.
Should work across multiple datasets and subplots.

def configureChart(self, chart):
	
	size = 6
	
	topPlot = chart.getXYPlot()

	# Create plot list depending if subplots exist				
	if  hasattr(topPlot, 'getSubplots'):
		plotList = topPlot.getSubplots()
	else:
		plotList = [topPlot]
	
	for plot in plotList:
		datasetCount = plot.getDatasetCount()
		for dsIndex in xrange(datasetCount):
			dataset = plot.getDataset(dsIndex)
			renderer = plot.getRendererForDataset(dataset)
			
			for seriesIndex in  xrange(dataset.seriesCount):
				shape = renderer.getSeriesShape(seriesIndex)
				shape.height=size
				shape.width=size
				shape.x = -size/2.0
				shape.y = -size/2.0
				renderer.setSeriesShape(seriesIndex, shape)

Default size of 6

Jordan,

This is better than I hoped. Thanks a ton!

Hi @JordanCClark and All,

Can we disable the shape for those lines in the single dataset? I have one dataset that contains four lines of chart. I'll give an Image for reference. I have Min, Max, Target, and Actual. These are the four Values I have in the dataset. I had to change the line into Line/Shapes in the chart properties. Then, all of the line styles are changed. But I should need to change the Line style for Actual only. Could you please help me to resolve this issue?

In Chart Customizer:

The above one is my dataset. The Manz ID is an X-Axis value, then HC CH5 590mm is the Actual value and threes are max, min, and target values.

Thanks,
Muniyandi D

I'd make a filter to use the specific dataset column names.

def configureChart(self, chart):

	size = defaultSize = 6
	seriesFilter = ['HC CH5 590mm']
	
	topPlot = chart.getXYPlot()

	# Create plot list depending if subplots exist				
	if  hasattr(topPlot, 'getSubplots'):
		plotList = topPlot.getSubplots()
	else:
		plotList = [topPlot]
	
	for plot in plotList:
		datasetCount = plot.getDatasetCount()
		for dsIndex in xrange(datasetCount):
			dataset = plot.getDataset(dsIndex)
			columnNames = list(dataset.getDataSetForSeries(0).getColumnNames())[1:]
			renderer = plot.getRendererForDataset(dataset)
			for seriesIndex, seriesName in enumerate(columnNames):
				if seriesName in seriesFilter:
						size = 0
				else:
					size = defaultSize
				shape = renderer.getSeriesShape(seriesIndex)
				shape.height=size
				shape.width=size
				shape.x = -size/2.0
				shape.y = -size/2.0
				renderer.setSeriesShape(seriesIndex, shape)

Thanks, @JordanCClark for your support. But I got an error whenever this script was run.

And the mentioned column's data line's shape size is also not reduced.

Pink - 'HC CH5 590mm'
Orange - Top - 'Max', Bottom - 'Min'
Green - 'Target'

Thanks,

Can you post a export of the window? If the dataset property is bound to something, remove the binding first, to preserve the data. I should be able to take a closer look this afternoon (currently, its 4am here :wink:)

EDIT: Also, what version of Ignition? Just to be sure I'm on the same page.

Thank You @JordanCClark for your reply messages at 4 am. I'll add an example window and one client tag for that chart. Should need to assign the substrate_id column in the tag as "Manz ID" fro that charts.

Chart_dataset_tags.json (96.9 KB)
Chart_Example_Window.zip (45.4 KB)

You can use this to Check and validate which error has throwing while running the script.

Our ignition version is 8.1.33 (b2023101913)

Thanks,

Sorry for the late reply. Work requirements are building up...

Anyway, here's a quick and dirty one that will hide series shapes only. No resizing, as, in my limited time, resizing a polygon is a pain. :laughing:

def configureChart(self, chart):

	seriesFilter = ['HC CH5 590nm', 'Target']

	
	topPlot = chart.getXYPlot()

	# Create plot list depending if subplots exist				
	if  hasattr(topPlot, 'getSubplots'):
		plotList = topPlot.getSubplots()
	else:
		plotList = [topPlot]
	
	for plot in plotList:
		datasetCount = plot.getDatasetCount()
		
		for dsIndex in xrange(datasetCount):
			dataset = plot.getDataset(dsIndex)
			columnNames = list(dataset.getDataSetForSeries(0).getColumnNames())[1:]
			renderer = plot.getRendererForDataset(dataset)
			
			# Create a shape to use for hiding a series shape.
			hiddenShape = renderer.getSeriesShape(0)			
			hiddenShape.height = 0
			hiddenShape.width = 0
			hiddenShape.x = 0
			hiddenShape.y = 0
			
			for seriesIndex, seriesName in enumerate(columnNames):	
				if seriesName in seriesFilter:
					renderer.setSeriesShape(seriesIndex, hiddenShape)
