No feedback on this so far :(

Does that mean:
  • That You can not reproduce the error?
    That the bug has been fixed in some later version ?
    That You have not received the files yet, or can not read them ?

Great!
Found the demo with an older 6 or 7.-something version.

I now have a fairly good log scale spaning several decades, if I want to.

As my scale may change at run time, I will have to come up with an algorithm to put in reasonable ticks, but this was the break needed! :cool:

Hi walker1, As Alexander suggests, to have labels and grid lines to appear per your request you should use custom axis labels. You can find an example at TeeChart's features demo. The example can be found at All Features\Welcome!\Axes\Labels\Custom Labels . Sounds like it might be an idea, but wher...

Sorry, but not too good :( With those parameters I get many more labels, but they keep on going in increments of 10. I.e. 80, 90, 100, 110, 120, 130 and so on. It is a slow death going all the way up to 1000 :roll: I am using the right axis, but I guess left and right will do the same given the same...

Logarithmic axis again

When I select logarithmic Y axis on a standard XY chart I seem only to get labels for the upper most decade. (all numbers 1 to 10) I then get minor ticks for the next (no grid lines) and then ... nothing. Which of the two zillion parameters could change this ? I don't need a label for every tick, bu...

I have uploaded a zip file (PolarDemo.zip) containing a demo (exe and all source) of the problem. The application places different values in the four quadrants. 316, 10, 31.6 and 100. The chart has just been brutally copied from my actual application with only little adjustment for this demo. The up...

Strange logarithmic scaling problem on polar plot

I have a polar plot, which can show either square meter or dB over 1 sqr m. The later uses log10 scale! When I change the scale in dB mode (plot is, of course, using linear scales) everything works fine. If I have set the boundaries to 0 and 5 (dB) my curve says 3.9 dB. Changing the lower boundary s...

I think I have solved it now! I recompiled the whole thing using Delphi (with all its updates), and then remembered :oops: :oops: to copy the newly compiled components, DCUs etc. into the directories made by the installer. Partly a so called Error 40. :oops: Where the error is located 40 cm from the...

Fully updated but still wrong RTLversion in TeeChart V. 7

In order to be able to take over the work of my colleague, I need to use version 7. Unfortunately I now get a compile error saying that this or that TeeChart mudule was compiled with the wrong RTLversion. I have uninstalled TeeChart version 6.01, installed Delphi RTL update 1, 2, and 3. (standard up...

Thanks for your reply, but i think my application with my polar plot problem would be too complicated to share with you. It is depending on other apps too.
But the fact is when i clear a series i seem to clear the rings too !!

Best Regards

Polar plot updates

How far are you in having Polar Plots support logarithmic grid and zoom functions etc. ? Will there be and update to implement these functions ? If so, when ? I have a "live" polar plot wich i clear and update a few times every secon. Applying drawring makes the ring flicker ! any advise ? Have a ni...

Polar Trouble

Hi

1. Which tools work on polar charts.
2. Trying to use an series function seems to result in a straight curve and not a"circular" one.
3. Is it possible to have a logarithmic grid. At least when you choose logarithmic axis.

Best Regards

Ole
