Vertical graphlines obstruct measurement result.

[h.batema]

While performing emission measurments with Radimation 5.8.16, the vertical lines of the graph obstruct the measurement values.
The representation of horizontal lines is correct, behind the measurement graph.
The vertical lines should fall behind the measurement graph not in front.
CAn this be solved by changing parameters or is this a bug in RadiMation 5.8.16?

It is indeed correct that the vertical graphlines are positioned on top of the measurement results. This was already known to us, but it was never pointed out to be a serious problem.
Your attachment however shows that this can result in incorrect results when a narrow emission is precisely on a 'nice' frequency (like the 200 MHz signal in your plots).

We are using a powerful third-party graphing module, but this module cannot show the vertical grid lines in the way we want. The vertical grid lines are therefor internally 'simulated' by drawing additional annotations that look like vertical gridlines. These annotations are however positioned on top of the measurement graphs, and therefor they could hide the measurement results.

We find this problem serious enough to investigate if we can find a solution. We will contact the manufacturer of the third-party graphing module to determine if we can find a solution.

There is a possibility to have a solution where the vertical grid lines are drawn below the measurement results.
But the disadvantage of that solution is that the markers of the detected peaks are also drawn below the measurement results. The markers (the little red circles and red numbers) will then be partly covered by the measurement results.
Would that be acceptable?

We have created an item in our database that contains all the wishes/remarks/etc...

This specific item is registered as:
#4080: Vertical grid lines of the graph are drawn on top of the measurements, which could hide measurement results

I continued to investigate this problem.
I checked our source code and that proved that we already implemented the drawing of the vertical graphlines, accoording to the suggestions that are written in the documentation of the 3rd party graph module.
At this moment it seems that this is a limitation of the used graph module.

I have also contacted the manufacturer of the graph module to discuss with them if this can be improved or fixed. We are waiting on their response.

Currently we experience an issue with a customer complaining that the measurment results were not shown accross the entire graph.
First of all it is of major importance that the tool will measure correctly, which means all values should be interpreted and remeasured if necessary.
The measurement results including peaks should be visible accross the entire plot, no matter where in the graph.
The proposed solution could be a decent work around.

Bottom line : the plot should not leave any room for discussion.

We totally agree with that. It is of high importance that the respresentation of the graph is correct.
That is also why we have given a high priority to this problem, and we are investigating the issue to find a correct solution.

We received a response from the manufacturer of the graph module that we are using.
He notified us that the problem is solved in a newer version of the graph module. In that version it is possible to place the vertical graphlines behind the data lines.

We will continue to upgrade the graph module to the latest version, and we will check if the problem is really solved. After that we will perform some additional verification of the correctness of the graph. We will create a new software version of RadiMation, which will include graphs where the vertical graphlines are correctly drawn.

Thanks for the update,
It looks promising to hear that the problem can be solved completely.

While performing emission measurments with Radimation 5.8.38, the vertical lines of the graph still obstruct the measurement values.
See attachment.
In my opinion this should be solved in the newer versions of RadiMation.
Could you please provide information regarding the RadiMation version when you expect this should be solved?

The problem where the graphlines of a graph are drawn behind the grid lines of the graph has been fixed in version 2012.1.6 of RadiMation.
Due to other issues, that RadiMation version hasn't been released in the past.

Today we released version 2013.1.6 of our RadiMation software, which fixes your problem. This new version can be downloaded from our webshop. (see: viewtopic.php?f=3&t=53 )
