Easy chart doesnt work in Vision Client Launcher

I am new user of Ignition SCADA. For learning this scada I am using tutorials from Ignition SCADA university. I have a problem with implementing Easy chart. In ignition Designer everything is working fine but in Vision Client Launcher is not reading TAG.
Would someone have solution for my problem?

Edit: if that were the case, the client launcher wouldn't work

No. Other tags works fine, just Easy chart does not working.

In Designer, go Project->Properties, under Vision/Permissions, enable Tag History, then save


Thank you.
It is working now. I just need to figure out how this chart would work faster.
