This is now the third exercise where the GUI no longer matches the course material. 

I have created a new chart and there is no “search” box to type into.

If I click on “+ Add data” and then select “Add a Time Series” a search box appears but I cannot find any time series starting with my Name Birthyear, i.e. if I search for:

Eric63:VAL_23-TT-92539:X.Value

It comes up with a whole list of Named Time Series but none start with “Eric63:”

So I just selected the first one even though it doesn't come up with “Exact match with external id”

Then I had to manually set my date range from 02/01/2023-02/29/2024

I czan’t be the only one experiencing frustration because  your training material doesnt reflect the actual GUI and there needs to be a new step to add whatever is missing so that the correct time series is created.

Hi ​@EricKimminau and thank you for contacting us. 

When you search for your time series you need to add the external id in your search so you can find your specific time series. The name will not be visible. I added a note in our courses so it`s clear. What you did is correct.  

I personally went through all the hands-on courses in the CDF fundamentals learning path and did some small updates. The courses were clear enough and updated except some small UI updates that we were not aware of. 
 

Please let us know if you have any issues moving forward with your learning material.

Why can I search for my created time series in all of the other parts of the course but I cant in Charts? Seems to be a significant bug. I just used someone elses uploaded time series data and I was able to complete the course.

This also doesn’t address that the course never mentions having to add the source nodes to be able to use them for the calculation.

I believe it also never mentions that you need to change the temperature for the results of the calculation also to Celsius. I'm going from memory on this one.

During the Assessment there are multiple actions requested to complete the assessment that you never actually covered in the course. This is considered bad form for any courseware. If you are going to test on it, you better cover exactly how to find the answer in the course. Failing to do so will cause frustration and it is unfair to the students.

I was able to struggle through this course and successfully completed it. I was able to pass the Assessment on my second pass. This course really needs to improve before we would roll it out to an enterprise. It is not ready for prime time.

I would also like to add that the Charts GUI does not properly update, refresh, resize or repaint. It is never discussed in the courseware how to properly resize the lower pane as the source and formula elements are added, how to organize and other than “connect the lines” how to actually select the endpoint circles to accomplish the task. I kept having to resize the lower pane so I could see all 3 elements and I had to completely reload the browser window to get updated visualization of the selected elements to display properly. I went through a bootcamp for Seeq and PIAF last week and their GUI has none of these shortcomings. Their training properly defined every required step to perform every required action and they had none of the sloppy GUI issues that CDF charts is exhibiting. Charts appears to be a beta application and needs a lot of work to improve its robustness.
