Chart Scripting - August 2022 - why is this feature so hidden?

rva — Mon, 29 Aug 2022 11:10:57 GMT

Hi!

Chart Scripting is a very well hidden new feature in Qlik Sense August 2022. I only found it mentioned in the release notes.

- It is not mentioned in the "What's new App": https://showcase3.qlik.com/sense/app/bcca6893-a1b3-4763-8c5d-55ca7679878b/overview

- I don't get the example working from help.qlik.com https://help.qlik.com/en-US/sense/August2022/Subsystems/Hub/Content/Sense_Hub/ChartLevelScripting/chart-level-scripting.htm

@Patric_Nordstrom : any advanced demos on this feature?

I played a little bit around, and this example is working for me.

Let P = HCNoRows();
For J = 1 to P
Put #hc1.measure.2(J) = HCValue(#hc1.measure.1, P-J+1) ;
Next

Still I'm not quite sure how helpful this new feature is in real world. So I would be glad about every example that shows some good use cases on this topic.

Thx,

Roland

I have found interesting video on this topic. Steven Pressland explains Chart Scripting in details. See attached file.

thx!

Best video on this topic I have seen so far.

@Steven_Pressland : can you provide the .qvf you used in the video somewhere!

Thx,

Now the feature made it to the Qlik Design Blog with some examples for download: https://community.qlik.com/t5/Qlik-Design-Blog/Chart-Level-Scripting-Use-Cases-Samples-and-Examples/ba-p/1981049

I guess the feature was somehow forgotten with all the AutoML hype. But I think we now have some good examples to work with this feature!

I tried to do the Sunflower spiral that Steven Pressland shows in the video but I get an error. Have any other tried it.

I use this script

ADD LOAD
RowNo()+1 as #hc1.dimension.1,
1 as #hc1.measure.1,
1 as #hc1.measure.2
Autogenerate(999);

let Theta = 0;
Let GoldenRatio = 1.61803398874989484;
Let GoldenAngel = 360-(360/GoldenRatio);

For i = 1 to 1000

Let Distance = Sqrt(i);
Let Theta = Theta + GoldenAngel;

Put #hc1.measure.1(i) = Distance * cos(Theta * pi() /180);
Put #hc1.measure.2(i) = Distance * sin(Theta * pi() /180);
Put #hc1.measure.1.attribute.1(i) = Mod(i, $(vColors));

next i;

And get this error
