#### Topic: Logarithmic scale & sub-sorting mode

Dear Ivan.

Hi

I tried to draw a plot on logarithmic scale (assume 10) and I want to show grid lines base on 1 (such below link)

but I could not adjust it. In the Axes setting, when I try to change the grid unit and tick unit to 1, it not work.

It seems by changing trick units, it change base of logarithm.

It seems to add an additional option to divide axes trick to desired number of grid (for example in x-Log-Axes on

the base of 3, could divide and show grid between 3&6 (4, 5 or 3.5 4 5.5 etc.)

Another suggestion, is about manage and show type of function list in the left hand side space:

It will be easy understood if any operation set below "mother Case"

For example assume you set some point series: S1 ; S2 ; S3

After that you right click on S1 and add trend line, the result function shows below S3. (the order of the sorted function is depending on time!) I think it will be better if trend line 1 show under S1, derivative of trend line 1 under the trend 1 and etc.

(I paint it in below)

My suggestion method: http://upload7.ir/images/32949937163444181093.png

Note that by right clicking and choosing insert tangent line/normal, it will be placed under "Mother" function. but in other operation, it is not.

Best regards
