Also at the end thinking about the implications of logarithmic and arithm. (linear) scale, it has more sense to use the arithm. for drawing lines at the end it is a linear relation. With the logarithmic at the end it is converting a line to a parable. In fact if you plot a chart with a long trend going from 1$ to 1000$ in arithm. scale you will see that at the end the trend is parabolic not a line (for example TSLA).
So summarizing for mid/short term I use linear, for assessing a long term trend I use log.
What is your opinion about this?
