Somehow the stacked bar function is not working as expected.
I am using Ignition V8.1.26
- create a new xychart with default values.
- change the both value display to column.
- both column selected "Stacked"
- the display is like this, only the bar height is increased, not stacked.
Both series need to be on the same y-axis. If you change
output temp, it will stack as expected
It resolved the issue.
I am looking for the other kind of stacked bar.
The current stacked bar is one above the other, I am looking for the one behind the other, so I can see the difference.
Is it possible?
That's not a stacked bar then. I don't know what you would call it and I'm not sure what use it would be if it looks like a stack and when the front bar obscures the rear bar. Where have you seen these used?
If you introduce a third, empty series or series of zero values you should be able to introduce a gap between each pair of side by side values. That should make it clearer for value comparison.
It will be used to check:
- what's the setpoint
- what's the feedback
- what's the error
I used a PI tool which can achieve this function.
If it is not possible to create it in Ignition, I can set the two values side by side, similar deal.
Thanks for the comments.
That is called a Layered Column Chart in Amcharts.
You can acheive that by adding the clustered key and setting it to false on both series - series.clustered
You can also set series.column.appearance.width and series.zIndex to 1 to bring it to the front
Just did it.
Thank you for the advise.
one more question:
you can see from the above picture that the x axis lists even number only.
What's the setting that can allows me to specify the x axis marker? I want to display all numbers (from 0 to 45).
Try lowering the value of
BTW, where can I find these kind of information?
Is there any user manual listing the details of all of the properties?
So far I am just wild guessing and trying every setting to see how it works.
I've been able to find most info I need by digging through the docs here https://www.amcharts.com/docs/v4
