Differentiate trendlines in log and arithmetic scales

[Djobydjoba]

Hi Mark,

For long term trends it is advised to use the log scale. So with long term trendlines.
A trendline drawn in a log scale is irrelevant in an arithmetic scale and vice-versa. So the trendlines should be displayed only for the type of scale they have been drawn.

And, just for the fun, a nice trendline in log scale on the Apple chart.

The same trendline cannot be drawn in the arithmetic scale

Hi Djobydjoba,

Okay, thanks for the feedback. FM currently just keeps track of the endpoints, and will plot those same endpoints on the graph, no matter the scale.

Yes, and this leads to incorrect trendlines when displayed in the other scale:

As with currencies, that would be nice to hide the trendlines drawn with the other scale.
