thank you for answering. Unfortunately we do not have this extension in our company. Any other idea or can I just download Vizlib for myself and use it? Or is there maybe a Qlik update coming with those features.
You will get a zipped file that you will need to unpack in the folder above. Close Qlik Sense and restart and you will see underneath Custom Objects (in front-end) a tab called Vizlib with the extension you just downloaded.
If you use Qlik Sense Enterprise, they also need to be installed, you can use them up to 5 people for free, for more user you need a subscription. You will get a lot of other extensions besides the bar chart that are worth working with. If you're interested in this, just send me a PM.
