In this view all measured points and the regression curve are plotted. The x axis is the time [sec], the y axis is the temperature difference [°C] on the measuring points. The curves are fitted on the cool end. The default setting is logarithmic x axis, but linear x can be also useful for analyzing short intervals. The number and distance of measured points is characteristic for the noise figure of the measurement, 2-3 points along a vertical line mean most measured values are the same, i.e. the noise is low.
