Summary0002287: Chart doesn't scale time axis properly
DescriptionLove the program and I use it all on my machines to monitor temperatures. But the charts stopped scaling properly in the latest version.

On my laptop, there are 5 temperatures that I can chart: GPU, HD0, Temp1, Core 0, Core 1. For most of them, the chart shows the past 13 minutes only. But for HD0, the chart shows all data since I last rebooted. So once I enable "HD0" chart, then the time scale for all charts is changed and the graph becomes compressed. All charts except "HD0" show a flat horizontal line.

See screenshot. Notice the "Start time" is more than 24 hours before the "End time".
Steps To ReproduceHave Speedfan running for 15 minutes or more. Under temperature charts, check the box next to "HD0".
Additional InformationThis didn't happen with older Speedfan versions. I'm not sure which version started the problem.

This is a 2009 laptop (Dell XPS 1340)

I attached a second screenshot that shows the chart looking as expected when I uncheck "HD0".

You are right. The idea is that SpeedFan shows all the available samples for the specific reading and, since HDs sample less frequently, this causes what you see. I need to rework the charting tab.
