Log scale is distorted

[NinjaTrader_Brett]

Hello,

Thank you for your patience on this.

I looked into this and the scale is actually correct and logarithmic.

Your test however is invalid.

The reason for this is that with drawing objects when drawn they are a set pixels in width on the canvas and thus a set size. The drawing object does not adjust for logarithmic scale. Because of this it is expected that you see this with a drawing object.

Hello Kinderlich,

Thank you for your post.

I will report this to my development team who is back in the office tomorrow. You should receive a reply back tomorrow as well.

Thank you!

the log scale is not correct.

if you put up say AMD (from free kinetic dataserver)

if you measure a distance from 2.5 to 5 with a box which is a double, like so http://screencast.com/t/KLHVX3gle

then if you move the box so that the bottom is level with 5 , the top should be a double as well, so, it should be 10, but... it actually is (under 9.5)

this testing procedure works correctly on other charting platforms like freestockcharts.com so there is a scaling bug in your code.
