Greetings, I have two tags one is temperature and one is length in power chart i want to bring the temperature in y axis and length in x axis. I tried other charts but they provide limited functionality unlike the ignition power chart. Thanks for any help provided! ---

- The Power Chart component doesn't have a historian. It accesses data from _Ignition's_ Historian module. - The Power Chart component is always datetime on the X-axis. You can't use it as an XY Chart (unless X is a datetime, of course). > [@ayushvarma9081](#): > > ... temperature in y axis and **length** in x axis. What do you mean by "length" in this case? Length as in "distance" or length as in "duration" (time)? If you show a sample of your data and a mockup (hand sketch or Excel chart) of what you want we can help you better. ---

Ignition's historian does not synchronized capture and storage of **different** variables. All storage is only correlated with **time**. Not only can you not do this with the Power Chart, you cannot do this with the native historian. Record temperature and length into a custom DB table, either with a script, or with a Transaction Group in the SQL bridge module. Use a named query and an XY Chart to display. ---

As others have said if you’re trying to do an X-Y plot of temp vs length it won’t work. But if you’re talking about length as in just adjusting the time scaling based on an external value you feed in then bind your number to PowerChart.props.config.unitOfTime and then the units to config.measureofTime ---

Please make it easy for us to help you by providing the information requested in earlier posts. > [@Transistor](#): > > What do you mean by "length" in this case? Length as in "distance" or length as in "duration" (time)? > > If you show a sample of your data and a mockup (hand sketch or Excel chart) of what you want we can help you better. You have now mentioned "a table" as well. Have you got this working?
