I need an easy to use line graph software that allows two Y axis, one on the left and one on the right. Can anyone help me with this?
There is an application called Graph. The software allows you to create graphs based on your input by choosing axes, orientation and coordination. You can download the application through the application's page at Software Informer. If you require help using the software, after installation go to Help > Contents > Get Started. The application is open source which means you can use it for all the needs you have as specified in the Terms of Service.
