Post From: Log-Scale is reset to linear scale mostly, if a consant-range is being applied and 0-valu.

Moin Moin. After having read "Interactive Scale Range not working with Logarithmic Chart Scale I made sure to read "https://www.sierrachart.com/index.php?page=doc/Scaling.html". It says.: "When any of the data in the visible chart bars has a negative or 0 value, then logarithmic scaling is automatically disabled. This also applies to studies as well which are set to use a logarithmic scale." This has the effect, that I can set a log-scale, whenever no 0-volume-bar is being displayed for the "Volume (ID:6)"study, but not, if 0-value bars are present. Hence, I wanted to suggest to not disable the log-scaling, if the user explicitly does provide a specific range to plot. The reasoning behind this, is that a radicand of 0 does correspond to its log-value of (-∞). But, as the user is providing values to display, as within the attached screenshot from 100 to 10000, there is aconscious decision to exclude the negative/imaginary value-range of the log-function. So, this one is a backwards-compatible change. If You want to make sure, that any customer, using this is aware of the change, then my suggestion is, to add a checkbox within the scaling menu, right below "Bottom Of Range" saying something like "even u se this range, if 0 or negative values are to be used within the logarithm". _Tschüß, __Michael.
