<br>
This is the first time that I post something, so please be patient with me :-)<br>
<br>
I have been using Plotpanel now for a while to plot Bode diagrams within Lazarus GUIs.<br>
Now I would like to switch to TAChart which seems very powerfull too.<br>
I tried it out with linear graphs and it works very well.<br>
<br>
But If I try to plot a bode diagram with a logarithmic x Axis then it crashes.<br>
I followed the tutorial about logarithmic transform:<br>
<a href="http://wiki.freepascal.org/TAChart_Tutorial:_ListChartSource,_Logarithmic_Axis,_Fitting" target="_blank">http://wiki.freepascal.org/<u></u>TAChart_Tutorial:_<u></u>ListChartSource,_Logarithmic_<u></u>Axis,_Fitting</a><br>
and I did all the steps successfully.<br>
<br>
BUT If I try to apply a logarithmic transform to the bottom axis (x-axis) then it crashes.<br>
It displays the graph but the grid lines are gone.<br>
Has anybody tried already to apply log transform to bottom axis? It works for left axis.<br>
<br>
Thanks<br>
