Inquiry about results display in the dashboard

[imedkh93]

Hello;
I have a question related with the demand outputs in CEA.
after entering the inputs and running the scripts, i tried to get the outputs from the dashboard , but it didn't succeed, i had this message in the place of the different charts and graphs.
Thanks in advance, i will be so grateful for your answers.

@imedkh93 Can you confirm you have generated demand results for this specific buildings and the issue is only in visualization?
To that you can check: project/scenario/outputs/data/demand and open the B1004.csv and the total_demand.csv files.
If you have outputs but are still not able to see this results and this error persists accross different scenarios, it might be a bug.
In this case, it is better to open an issue at:
https://github.com/architecture-building-systems/CityEnergyAnalyst/issues

First, thank you sir for responding
I found this problem with CEA Version 3.26.0
After sending this help request, I tried to install CEA Version 3.31.0, and all worked in a good way, I didn't face the same problem.
My greetings.
