How to plot two variables in a XxY chart

Hello, I would like to know what is the best way to plot two variables in a XxY chart instead of stacking them. For example: I have “variable A” and I want it on Y axis and “variable B” on X axis instead of timestamp. Is it possible to do it using Charts, Canvas or should I do it on Power BI?

Best practice for joining data in models

I am creating a transformation where I am joining data from two different views/containers, where table B has a node reference to table A. I have tried to find documentation for this, but I have not found any so far.  Through friends and trial and error I have found two options, and neither seems to be performing well. Example:Type A {    Name: String}Type B{   Name: String   A_ref: A}What I have found as possible solutions are to go through cdf_data_models and picking the externalId from the node-reference:from cdf_data models(<spc>, <mod>,<ver>, “A”) as A join cdf_… as B on A.external_id = B.A_ref.externalIdSame as above, but join on a as a nodereference: on B.A_ref = node_reference(<spc>, A)   Neither of these options seems to be documented anywhere, and I can’t find any other ways documented. The performance when reading when using these joins seems slow, even though I have set up a few indexes which should cover the different joins. This is also slower then

Unable to calculate on Charts

Hello, I am trying to perform a calculation on Charts but it does not work. It is a multiplication of 4 time series, all of them with a resample to granularity to 1m. One of them has real values and 3 of them are 0/1 steps. When I zoom out, I can see the calculation and it shows a pick of values, that is not accurate as it shows average data. Although when I zoon in to see the data, the trend disappears, the error says “One of the time series has less than two values”. As I resampled the data to 1 minute, I was expecting to see one values per minute, but it does not seems to happen. Is there other way to calculate the data correctly? Zoom in:

How to convert xml coordinates to fit CDF

The coordinates of a document in CDF are normalized. In a normalized document, it has (0,0) coordinates in the upper left corner and (1,1) coordinates in the right bottom corner.Convert xml coordinates to normalized coordinatesTo convert xml coordinates to normalized coordinates you need to divide X coordinates with the width of the page and the Y coordinates with the height of the page. If the xml Y coordinate is 0 at the bottom of the page and the <height> is at the top of the page, the Y coordinate should be flipped as below.Normalized Y = 1- Normalized YOnce the coordinates are flipped;NewMinY = 1 - OldMaxYNewMaxY = 1 - OldMinY Example scenarioIf a user would like to add manual annotations to a P&ID file in CDF the user should convert the xml coordinates of the file to normalized coordinates.

The number of assets shown as linked to the file is not correct. The system is wrongly showing the number of assets linked in the file.

The number of assets shown as linked to the file is not correct. The system is wrongly showing the number of assets linked in the file.And also Linked Asset to an asset count is wrong and same issue for linked files, linked time series, Linked events. These linked is different than directly linked items. (A) Linked (Files): this count means all decedent children of a given asset. (B) Directly linked (files): this count is the number of files that are connected directly to the asset. (C) The file count on top: This count may vary since there might be duplicated IDs amongst the different types - the total number is a distinct value. The linked assets are not relevant to the Asset which user try to refer and these Linked assets will not linked to the Asset.Directly linked assets are linked to the assets which user try to refer.User don't want to see linked asset tab in CDF because its doesn't have a meaningful assets linked to it, however Directly linked asset have meaningful tab and same

Incorrect handling of "del_zero_val" option in Charts function

Hi,I’m using the Charts function “Statistics/Outlier Removal” and noticed that the option “Remove zeros” (aka del_zero_val) does the exact opposite of what one would expect.  Example of a data stream filtered without “Removes zeros” Example of a data stream filtered with “Removes zeros”Is this a bug or the intended behaviour? If the latter then I think the naming/documentation is misleading.

Unable to link an engineering diagram to assets

While doing the CDF Fundamentals, I’ve found out that if you don’t select a Data Set ID while uploading your PDF file, you later won’t be able to link it to your Asset, as your Data Set won’t be found. Also I didn’t find a way to edit this later. I had to upload a new file and select my Data Set ID. Is this expected? What was confusing to me is the fact that the Data Set ID is marked as optional. If this is not the case, this should be flagged as mandatory in order to upload any file.

Canvas: Y axis "unmerges" when inserting Chart

When displaying many similar time series together in Charts, it is useful to select “Merge unit” to reduce the number of Y axes. This functionality does not follow the chart when inserted in a canvas. Have I missed something here?
