  Charts not showing after trying to delete files in tmp_chart_cache folder

Hi... I have installed Chart Director on my linux server and it has been working fine. Then I tried to delete the thousands of xml files in the  temp_chart_folder without success and now the charts do not show anymore.

Can you please advise how I fix this? Thank-you. Andre.

Hi Andre,

Would you mind to clarify what is the relationship between tmp_chart_cache, the XML files and ChartDirector?

ChartDirector will not use or create XML files, and it will not automatically use the tmp_chart_cache directory. However, it is possible that your charting code has instructed ChartDirector to store chart images in that directory. Would you mind to clarify if this is the case?

A possible explanation of the issue is that some other code in your system is using the XML files. For example, your database code or data acquisition code may be using the XML files. When some or all of the XML files are deleted, the database code or data acquisition code may not work, and so downstream features (such as creating charts, which requires data) may not work.

To identify the cause of the problem, the error message would be very useful. Would you mind to inform me what is the error message? Also, you would mind to clarify what the XML files are used for? Which code in your system create or use those files?

Regards
