Re: Xaxis Labels as Dates

Chris,

just an idea: did you specify "sdl_sdlbase" in the "uses" statement?

Re: Xaxis Labels as Dates

Hi Chris, I suspect that the identifier "ftDateDime" is declared in another unit as well.

Re: Create Custom plot series

Hi Talal,
sorry for the late reply....

Re: ReportListview with cyrilic alphabet

Hm, I've to admit that I never tried this. But I suspect that you have to set the Font property accordingly.

Re: Multi-layer 2D Contour Plot

Hi Paul, you cannot put two contour plots on top of each other (in the sense of stacked transparent films). However, if you want to draw your own custom lines on top of a contour plot you can use the event "OnDataRendered". See http://www.lohninger.com/helpcsuite/ondatarendered_contourplot.htm for t...

Re: RChart zoom moves lines

Hi Kevin,
this effect most probably results from rounding effects when you zoom in too far.

Re: CurveFit demo not fully working

Hi Bruce, there seems to be a bug in the program which disables the input of new data points after clearing the data and setting the first point. As a quick workaround you can click the "pencil" button once again after setting the first point. Afterwards you can enter additional points. Let me know ...
